tmuxinator won't run untill another tmux session exists #536

Kayne · 2017-06-06T09:31:28Z

Tmuxinator can't connect to tmux server (create new sessions) unless at least one session exists already.

When I have no sessions live and try to run tmuxinator project:

~  tmux list-sessions
no server running on /private/tmp/tmux-501/default
~  tmuxinator project_name
no server running on /private/tmp/tmux-501/default
lost server
no server running on /private/tmp/tmux-501/default

no server running on /private/tmp/tmux-501/default
no server running on /private/tmp/tmux-501/default
no server running on /private/tmp/tmux-501/default
no sessions

(the /private/tmp/tmux-501/default exists and is empty)

But when I create new tmux sessions (and at least one still exists):

~  tmux list-sessions
0: 1 windows (created Tue Jun  6 11:22:21 2017) [134x32] (attached)

all works fine, tmuxinator run tmux session and all commands are executed correctly.

I'm using tmux 2.5 (OS X 10.12) installed via homebrew.

The text was updated successfully, but these errors were encountered:

firedev · 2017-06-08T02:14:06Z

Same here, something changed recently. Thanks @Kayne for a workaround so I can at least launch it.

vanife · 2017-06-08T06:43:30Z

This must be the change in the tmux 2.5. Reverting back to tmux 2.4 works fine (brew switch tmux 2.4).

Kayne · 2017-06-08T08:08:38Z

@firedev happy to help :)

@vanife Yes, reverting back to 2.4 fixes the problem. So it is definetely related to tmux version 2.5. I have to remember to not run brew cleanup everytime after updating formulas, because installing obsoleted packages is tricky :)

Skulli · 2017-06-12T06:13:46Z

Just had the same problem on my mac, workaround is working

adamstrickland · 2017-06-12T18:54:02Z

This has been tracked down to a change in behavior with respect to tmux has-session, which tmuxinator uses to detect if it should set up a new project or attach to an existing one. I have filed an issue; will update when we have a plan. Until then, tmuxinator does not support tmux version 2.5 or greater.

JBlackCat · 2017-06-13T16:54:11Z

👍 I should have checked here sooner. 😄

staycreativedesign · 2017-06-15T16:25:18Z

pretty easy question how would I install tmuxi2.4 on a mac?

Kayne · 2017-06-15T17:36:44Z

Install formula from specific revision (I belive it's how it's called in git):

brew install https://raw.githubusercontent.com/Homebrew/brew/2d2034afc6e4dfab0a1c48f5edd2c5478576293b/Formula/tmux.rb

staycreativedesign · 2017-06-15T18:48:09Z

Yay!!

UPDATE: the bug in tmux that was causing this issue has been fixed in master and will become part of that tool's 2.6 release. Unfortunately, the fix won't be back-ported to 2.5. If you really must have tmux 2.5 and use it with tmuxinator, you can pull the 2.5 branch from Github, apply the patch in the linked issue (also here) and be on your merry way. However, I would recommend simply sticking with 2.4 and jumping to 2.6 when it is released.

staycreativedesign · 2017-06-16T01:59:42Z

Thank ye sir!

danshumaker · 2017-09-18T14:37:39Z

Upgraded to sierra last night and started getting this error. But, just tried compiling 2.6-rc on tmux and checked the contents of cmd-find.c to be sure the patch was included, and it is. Linked my compiled version to the /usr/local/bin dir and re-ran tmuxinator without a previously running tmux and I still get the error.... bummer. I must be doing something wrong. rc3 For now I'll just start dummy tmux session to use tmuxinator so it has something to start with. Anyone else try tmux 2.6? (tried with tmuxinator 0.9.0)

JBlackCat · 2017-10-16T17:43:46Z

@danshumaker I was having the same issue.

Take a look at your tmux config. I am using the same config as my co-worker who is a bit more savvy than I with tmux and 2.4 broke a number of things in his config.

Once I updated my config the problem went away. I don't know which specific issues were causing the problem; my co-worker had made numerous changes since I first copied it over.

jenrzzz · 2017-11-03T02:33:46Z

For me the line set-option -g status-utf8 on was causing the issue (the status-utf8 option is obsolete). I really would have expected a more visible error message and it was very strange that starting tmux directly worked, but everything was peachy after I removed that line.

henvo · 2017-11-08T08:37:46Z

It seems that tmux changed some of its behavior that has to do with the .tmux.conf. For me it was the line:

bind r source-file ~/.tmux.conf ; display-message "Config reloaded.."

that caused the trouble. It always worked until I upgraded to the latest version of tmux. After removing this line from my .tmux.conf I was able to run mux start [project] again without any problems.

adamstrickland · 2017-11-08T13:50:33Z

@henvo can you double-check your syntax? pretty sure the ; needs to be preceeded by a \, e.g. (from my ~/.tmux.conf)

bind-key e copy-mode \; send-keys "?Error" C-m

Also, what versions of tmux and tmuxinator are being run?

adamstrickland · 2017-11-08T13:52:24Z

@danshumaker were you able to get things working? I'm a bit surprised by tmux 2.6 having issues... I personally have noticed that if I have multiple versions of tmux on my system I have to be careful about my $PATH, as tmuxinator will only find the first...

wanyaoqi · 2018-02-02T02:51:34Z

`~ » tmux -V

same problem in tmux 2.4

adamstrickland · 2018-02-02T14:49:35Z

@wanyaoqi I'm not sure this is the same problem... The line of code that introduce the problem this issue refers to was introduced after tmux 2.4 was released. As others have noted in the comments above, there are some tmux configuration settings that can cause something similar.

That said, if you think this is still tmuxinator-related, we'd be happy to help. Feel free to start a new issue and include your tmuxinator debug output and we can take it from there.

dkrieger · 2018-03-28T12:43:14Z

I still run into this issue in 2.6 . Adding the following to my ~/.zshrc did the trick. Of course, this could be bundled up in a script or alias, but I wanted it to be run any time my shell starts and no tmux sessions are found.

DUMMY='dummy'
PROJECT='monit'
tmux list-sessions || ( tmux new -d -s $DUMMY && tmuxinator start $PROJECT )

danshumaker · 2018-03-28T13:26:09Z

@adamstrickland Sorry for the late response, I do not have this issue anymore. Woot woot!

adamstrickland · 2018-03-28T13:36:43Z

@dkrieger Interesting... Thanks for the snippet; I'd be interested to know if others use something similar (if you do, maybe just +1 the comment?) over time. If so, maybe we incorporate the same into tmuxinator in a future release.

nickhoffman · 2018-04-22T16:13:07Z

I have tmux 2.7 and tmuxinator 0.11.1 installed and this problem affected me. The problem disappeared when I removed all of my tmux config files, which enabled me to identify the cause: the option status-utf8 was removed from tmux, but I still had this line in my config:

set -g status-utf8 on

Removing this line, as described in this comment above, fixed the problem. For more info, see tmux/tmux#230.

Set UTF-8 in status bar is no longer necessary. More info: tmux/tmux#230 tmuxinator/tmuxinator#536

eric-wieser · 2018-05-08T19:48:34Z

I'm running into trouble here with tmux/tmux#182 - running tmuxinator debug my-project shows that it's running tmux start-server, but that command no longer does anything

gnapse · 2018-08-20T14:48:36Z

I didn't use to have this problem, but I get it now that I switched to fish as my shell. In zsh it works fine, but in fish it does not. In both cases I have the same tmux configuration.

This is the output that I get when I run tmuxinator my-project:

lost server
no server running on /private/tmp/tmux-501/default
no server running on /private/tmp/tmux-501/default
no server running on /private/tmp/tmux-501/default

no server running on /private/tmp/tmux-501/default
no server running on /private/tmp/tmux-501/default

Again, the above only happens under the fish shell, not under zsh.

@gnapse if you are still having a problem do you mind starting a new issue for it? If it turns out to be related we’ll link the two so people can find them

adamstrickland · 2018-12-31T14:42:18Z

@episage I’m not seeing where tmuxinator fits in here. Assuming you are using tmuxinator, we should start a new issue for this as yours involves tmux-cssh, which may or may not affect what’s going on. If you do decide to create an issue, please include the tmuxinator debug output. Just FYI, tho, this is the first time I personally have heard of tmux-cssh, so there’s no guarantee we’ll be able to get it working, but we’ll see what we can figure out.

drewfish · 2019-01-20T22:42:12Z

I had the same problem with tmux/bionic-updates,now 2.6-3ubuntu0.1 amd64 installed on Ubuntu. When I switched to 2.8 installed via linuxbrew it seems to work again.

yam-liu · 2019-06-02T03:03:42Z

It seems there are some wrong configs in my .tmux.conf, use tmux to start tmux session will show the errors/warings. When fixed, mux [project] works again.

turboladen · 2019-06-06T18:35:26Z

FWIW, I landed on this issue after running into the same, initially described issue. Turned out my tmux.conf was a few years old and tmux had changed how it wants you to specify style; updating these style-related settings got me up and running. For example:

# I used to have this
set -g status-fg white
set -g status-bg black

# But I changed to this
set -g status-style fg=white,bg=black

You can see more about what I ran into over here: tmux/tmux#1689

kleinjm · 2020-01-06T15:40:11Z

My issue was that I updated tmux to version 3.0a and that broke on the backslashes in my conf file. I needed to change

bind \ split-window -h -c '#{pane_current_path}'
bind -n C-\ if-shell "$is_vim" "send-keys C-\\" "select-pane -l"

to

bind \\ split-window -h -c '#{pane_current_path}'
bind -n C-\\ if-shell "$is_vim" "send-keys C-\\" "select-pane -l"
