I am using cygwin and had the same problem. This worked for me:

 }

 # prefix + I - downloads TPM plugins and reloads TMUX environment

[jbnicolai]

@vascoosx can you explain why?

[vascoosx]

@jbnicolai I do not know.
It used to work without that patch and I checked the existence of /dev/null and it was there. I also tried to see if an error occurred with ls > /dev/null but there was no issue.

[TimDeve]

I get the same error, It doesn't seem to download the plugins at all. Weirdly it seems to work normally on babun, don't know what they are doing differently...

Edit: The only difference I can see is that cygwin's tmux is 64bit while babun's is 32bit.
Edit 2: Installed cygwin in 32bit and it works now, so there's that.

[wd]

For everyone get 127 error, make tmux command available for all users may be fix this problem.

I'm using a mac, and install tmux use homebrew, it will be installed at /usr/local/bin/tmux, after I make a symbol link to /usr/bin/tmux, everything will be working.

$ sudo ln -s /usr/local/bin/tmux /usr/bin/tmux

[dpremy]

I too was having this issue on OpenBSD 5.9 and 6.0 on 64bit.

For me this was as simple as installing bash as only sh is installed by default.

[luisdavim]

In newer versions of macOS you can't write to /usr/bin, not even with sudo.
So you can't run:

sudo ln -s /usr/local/bin/tmux /usr/bin/tmux

For anyone else having this problem you need to reboot your mac and press ⌘+R when booting up. Then go into Utilities > Terminal and type the following commands:

csrutil disable
reboot

This is a result of System Integrity Protection. And it is not recommended to disable it.

[smurex]

@luisdavim did you find any other workaround or is disabling the System Integrity Protection the only solution?

[shouya]

@smurex I've got this fixed. This problem is because tmux's run-shell command runs a shell which doesn't read from user configs, thus tmux installed in /usr/local/bin will not be found.

A better solution is shown the next comment, please ignore this one.

```
cd "$(dirname "$0")"

export PATH="/usr/local/bin:$PATH"

# plugins you need
plugins/tmux-yank/yank.tmux
plugins/tmux-recurrect/resurrect.tmux
plugins/tmux-prefix-highlight/prefix_highlight.tmux
```

~~~Then comment out all `run-shell/run` lines in your `~/.tmux.conf`, and add `run ~/.tmux/run.tmux` at the bottom. If you have extra configurations to the plugins, leave them as is.~~~

[shouya]

A better way to get around with this is to insert the following line:

set-environment -g PATH "/usr/local/bin:/bin:/usr/bin"

before the first run-shell/run command in your ~/.tmux.conf file, and leave everything else untouched.

[akashagarwal7]

@shouya is this solution supposed to work if we add the line at the top of .tmux.conf? I tried both on top of the file and before the first run command. It isn't working. Perhaps this requires a restart of tmux server?

[shouya]

@akashagarwal7 You might need to restart tmux server for the changed config to apply.

[llinfeng]

I too have got a 127 error, but that is solely due to my mistake: I did not fetch the tpm at all. The following line fixed my 127 error:

git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

[noboruma]

@akashagarwal7 make sure you do not have set -g update-enviroment that contains PATH. Otherwise, the set-env will be ignored.

[kelp]

I'm getting this on OpenBSD 6.5 with the OpenBSD stock tmux.

The reason is because this runs $HOME/.tmux/plugins/tpm which runs $HOME/.tmux/plugins/scripts/check_tmux_version.sh. That script contains at call to tmux -V on line 52.

The OpenBSD version of tmux does not have the -V flag. Not sure of the right solution though, still too new to tmux to know if the OpenBSD version has the features you require.

[AdamReece-WebBox]

Cygwin users:

You can get further insight by executing the installation script directly with ~/.tmux/plugins/tpm/scripts/install_plugins.sh. I found this was showing "download fail" for all plug-ins. On further inspection it was the git command specifically causing it.

Looks like there was a possible conflict between "Git for Windows" and Git through Cygwin's package manager. I resolved this problem by adding the git package via Cygwin installer, then remove it, then restart tmux so that Git for Windows is used.

Finally, I still get code 127 by pressing prefix + I, though calling the script it invokes directly with .tmux/plugins/tpm/bindings/install_plugins works fine:

TMUX environment reloaded.

Done, press ESCAPE to continue.

Possibly related is the space in my user profile path? '/cygdrive/c/Users/Adam Reece/.tmux/plugins/tpm/bindings/install_plugins'

[zyfyy]

I got the error simply because of wrong path ~/.tmux/plugins/tpm/tpm

[phaalonso]

I too have got a 127 error, but that is solely due to my mistake: I did not fetch the tpm at all. The following line fixed my 127 error:

git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

I have the same problem, verify if the ~/.tmux/plugins/tpm exist or clone it.

[ical10]

I too have got a 127 error, but that is solely due to my mistake: I did not fetch the tpm at all. The following line fixed my 127 error:

git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

this problem still exists (at least in my machine), tmux 3.1c, zsh 5.3, macOS Mojave, and cloning the non-existing tpm plugin fixed it!

[AdamReece-WebBox]

Thanks for the suggestion. Unfortunately that doesn't resolve the issue on Cygwin.

[carlosonunez]

If you are using Homebrew >3.0.0, you'll need to add this to your PATH in tmux.conf:

set-environment -g PATH "/opt/homebrew/bin:/usr/local/bin:/bin:/usr/bin"

Notice /opt/homebrew/bin.

Does the path to your home directory have any spaces?

[bennypowers]

Does the path to your home directory have any spaces?

I should have mentioned earlier, this is in hyper terminal as well as macOS terminal

[EdmundsEcho]

As a testament to how good this plugin manager is, I rarely have to deal with it. As a result, I seem to have forgotten a few things when getting my MI MacPro up and running. The mistake was evident when I got the 127 message described in this issue.

Just to share what I should have remembered to perhaps benefit the next:

1. make sure to install tpm; unless your config checks for it each time...

2. for whatever reason, I now need to include the following just before the run "$HOME/.tmux/plugins/tpm/tpm" command (I suspect that my previous .profiles and the like, set the path in addition to what I was doing with fish; not so in the fresh new system):

     set-environment -g PATH "/opt/homebrew/bin:/usr/local/bin:/bin:/usr/bin"
   

3. Once you restart your tmux server (or try to trigger the install with tmux source ~/.tmux.conf), you can test/confirm the plugin manager is working as expected by updating your plugins:

     `Prefix U`
   

The command generates a message with a list of all of the installed plugins, and an option to update any one of them by name or "all". You may need to run this twice in order to get the full list.

pdating all plugins!                                                                                     [0/0]
  "tmux-yank" update success
  "tmux-resurrect" update success
  "tmux-sensible" update success
  "tmux-battery" update success
  "tpm" update success
TMUX environment reloaded.
Done, press ENTER to continue.

I hope this helps.

Moved to WSL2 with Ubuntu-20.04

This is my environment:

> tmux -V
tmux 3.0a

This is my TPM config in .tmux.conf

# TPM
# list of plugins
set -g @plugin '.tmux-plugins/tpm'
set -g @plugin '.tmux-plugins/tmux-sensible'
set -g @plugin '.tmux-plugins/tmux-yank'
set -g @plugin '.tmux-plugins/tmux-open'
set -g @plugin '.tmux-plugins/tmux-resurrect'
set -g @plugin '.tmux-plugins/tmux-continuum'

set -g @continuum-restore 'on'

set-environment -g PATH "/usr/local/bin:/bin:/usr/bin"
run '~/.tmux/plugins/tpm/tpm'

This is what I get when running the install script:

> ./.tmux/plugins/tpm/scripts/install_plugins.sh
Already installed "tpm"
Installing "tmux-sensible"
  "tmux-sensible" download fail

This plugin manager never worked for me.

Hi,

I recently had a similar issue in WSL2 with Ubuntu-20.04.

Reloading the tmux config was giving me the original error from this issue:

'~/.tmux/plugins/tpm/tpm' returned 127

TMUX environment reloaded.

Done, press ENTER to continue.

In my case, it turned out that the problem was not with tpm itself, but with my git configuration.
I was loading these plugins:

set -g @plugin 'tmux-plugins/tmux-battery'
set -g @plugin 'MunifTanjim/tmux-mode-indicator'
set -g @plugin 'schasse/tmux-jump'

I tried to execute any of them manually, and I realized they were all failing for the same reason: they had CRLF endings.

I have "autocrlf = true" in my .gitconfig. Changing the value isn't an option for me, so I changed my git attributes file instead:

~/.gitconfig

[core]
     attributesFile = ~/.config/git/gitattributes

~/.config/git/gitattributes

*.sh text eol=lf

After deleting all my plugins and using tpm to download them again, everything worked perfectly. I didn't even need to keep the line "set-environment -g PATH "/usr/local/bin:/bin:/usr/bin"" in my tmux.conf.

I hope this helps.

[paulcobbaut]

I got the same error on Debian.
Solution: After "apt install tmux-plugin-manager", the correct path is "/usr/share/tmux-plugin-manager/tpm".

[back2childhood]

I too have got a 127 error, but that is solely due to my mistake: I did not fetch the tpm at all. The following line fixed my 127 error:

git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

this operation solved my 127 error, but then I have a 1 error

'~/.tmux/plugins/tpm/tpm' returned 1

[sgessa]

Just tried installing TPM from a fresh FreeBSD 13 installation, using zsh as default shell.
It works but it requires bash which wasn't installed by default (and git of course).

[kamalkech]

@devnoot i get the same issue, can u share any solution ??

[devnoot]

@kamalkech see @sarahlagh 's comment and check your git settings. I fixed my issue by removing the autocrlf = true line.

[zh1C]

@devnoot i get the same issue, add code set-environment -g PATH "/opt/homebrew/bin:/usr/local/bin:/bin:/usr/bin" not working, why?

[syntaxler]

I ran into this issue on OpenWRT. Turns out tpm needs bash to function since it is a bash script, just install bash even if you don't use it yourself.

Same issue, whether I have plugins referenced or not, always getting error 127. Recently upgraded to Ubuntu 22.04.2 LTS for WSL2 I'm almost certain that's the issue but no solutions referenced here fix the issue.

Edit of shame: although I thought my ansible script had cloned the tpm repo, it hadn't, I simply didn't have tpm cloned...

[rickypang0219]

Hi, I encountered the same problem when I install tpm via home-brew in my MacBook (macOS 13.5) last night. I solved my problem by including

set-environment -g PATH "/opt/homebrew/bin:/usr/local/bin:/bin:/usr/bin:/usr/sbin:/sbin"

run '/opt/homebrew/opt/tpm/share/tpm/tpm'

inside my tmux.conf file based on above suggestions.

However, there were some unusual things happened when I was configuring my tmux. The first thing was that if I did not include /usr/sbin:/sbin in PATH, tmux cpu/gpu stat could not be displayed properly. Besides, tpm home-brew page says that I should include run '$HOMEBREW_PREFIX/opt/tpm/share/tpm/tpm' in my tmux config file but return 127 happens. Once I change back to run '/opt/homebrew/opt/tpm/share/tpm/tpm' , I can run tpm without any issue, though they should be the same,

[adam-coates]

Hi I encounted the problem using WSL windows running Ubuntu. I am not exactly sure how I solved the issue but it was a combination of running the following:

bash -x ~/.tmux/plugins/tpm/scripts/install_plugins.sh

Then if the some plugins appear installed then, I tried to create a symbolic link as per @wd first comment

$ sudo ln -s /usr/local/bin/tmux /usr/bin/tmux

Then I noticed that I get an "tmux tpm returned 1"

Next I checked since running WSL that git is installed on the Ubunutu instance and then installed git using homebrew.

I then removed the symbolic link and checked again if the plugins could be installed or not

bash -x ~/.tmux/plugins/tpm/scripts/install_plugins.sh

After this I then changed the run command at the bottom of the .tmux.conf
from run '$HOME/.tmux/plugins/tpm/tpm' to run '~/.tmux/plugins/tpm/tpm'

After doing all these steps tom stopped returning 127 and stopped returning 1.

[babzcraig]

Had this issue recently. I tried a number of solutions listed here but none worked. I had to kill all running tmux sessions with tmux kill-server. After that, I started a new session, ran the install commands again and it worked

[ArykLAnderson]

I had this issue on M3 MacOS 14.3.1
I had installed tmux with homebrew. Trying to source the tmux configuration file would not work at all with the cloned git repository, with any of the suggested path updates prior to running that command. I was able to get it work by installing tpm via homebrew as well and including
run '/opt/homebrew/opt/tpm/share/tpm/tpm' as rickypang0219 mentioned above, and this works without including any path updates

[daaanny90]

I'm kind of stuck in this. I'm using MacOS 14.3.1 with iTerm2 and tmux 3.3a.

I've tried all the solutions above, including the last one that should perfectly fit my case, without success (although the last one from @ArykLAnderson is the one that produced some improvement).

I'm at the point where my configuration correctly reloads and installs the plugins (but I'm not sure if this really worked, as I have a theme installed but it doesn't show up), but then, if I try to reload it again or I open a new session, I get:

'/opt/homebrew/opt/tpm/share/tpm/tpm' returned 1
'~/.tmux/plugins/tpm/tmp' returned 12

I would like to avoid uninstalling and reinstalling iTerm2, and I think this should be fixable even without uninstall/reinstall stuff.

Clearly there's something in my setup that doesn't work or I did something wrong at some point. Does anyone have any advice for me?

Here is my .tmux.conf
