t2: command not found

[TAMHAN]

Hello Folks,
sitting here on Ubuntu 14.04, with Node.JS 6.10, and cannot install Tessel CLI. The NPM installation process runs, but does not create the t2 binary:

tamhan@TAMHAN14:~$ sudo npm -g install t2-cli

I'm getting this too.

t2/t2 list commands say t2: command not found

My npm install -g t2-cli is slightly different with
sh: t2: command not found
sh: t2: command not found
+ t2-cli@0.1.22

[HipsterBrown]

@TAMHAN @newcasio after looking at a similar issue (#1085), can you try running sudo /home/tamhan/.npm-global/bin/t2 install drivers or sudo /home/tamhan/.npm-packages/lib/node_modules/t2-cli/bin/tessel-2.js install drivers?

[newcasio]

@HipsterBrown I have tried both commands. The first one returns
INFO No driver installation necessary.
The second returns a message Users/daniththai/.npm-packages/lib/node_modules/t2-cli/bin/tessel-2.js: command not found.
I am new to programming so I have copied your command character for character.
Thanks for trying to resolve this.

[HipsterBrown]

@newcasio Are you on Linux or another OS? What version of Node and npm are you using?

[newcasio]

@HipsterBrown Mac OS.
Node version 11.6.0.
npm version 6.5.0-next.0.

[HipsterBrown]

Ok if you uninstall t2-cli (npm uninstall -g t2-cli) and re-install it (npm install -g t2-cli), what is the output in your terminal?

[newcasio]

Sorry about the formatting but this is the output.

[HipsterBrown]

It appears to be installing correctly. What does which t2 output?

[newcasio]

No output. It just goes to the next command line.

danith-thais-imac:tessel daniththai$ which t2
danith-thais-imac:tessel daniththai$

[HipsterBrown]

Ok I think I might know the issue. I don't think your terminal PATH is set up to look under ~/.npm-global/bin for globally installed packages. You can confirm that by running echo $PATH and looking for .npm-global in the output.

If you have a ~/.bashrc or ~/.bash_profile, put the following line in there, save it, start a new terminal session, and try running which t2 again.

export PATH=~/.npm-global/bin:$PATH

[newcasio]

I did originally have the EACCES issue that is mentioned on the Tessel installation page and followed the directions on the npmjs page which includes running the export PATH=~/.npm-global/bin:$PATH command.

When running echo $PATH in the ~/.npm-global/bin folder I don't see .npm-global.
Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/mongodb/bin:/Users/daniththai/.rvm/bin

[TAMHAN]

Hello,
even though I havent used Tessel at all since this bug report, here is the content of PATH on my workstation as of today:
tamhan@TAMHAN14:~$ echo $PATH
/home/tamhan/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/sbin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin:/opt/microchip/xc8/v1.38/bin:/opt/microchip/xc8/v1.38/bin:/home/tamhan/.npm-packages/bin

Please be careful as it probably has changed since when I used tessel last.

Tam, just trying to be a good citizen

[HipsterBrown]

@newcasio ~/.npm-global/bin needs to be in your PATH to use any globally installed package from npm. You need that export PATH=~/.npm-global/bin:$PATH command to be run whenever you start a new terminal session, so it needs to be in your ~/.bash_profile file.

[newcasio]

@HipsterBrown Thankyou very much for your help. I went missing for a little bit there, but have comeback to try with your suggestion, and all is working now.
Cheers.
