Yarn global command not working

Update Dec 2018

Just updating the path didn't work for me. I had to also set the yarn prefix.

• Ubuntu 18.04.1 LTS (bionic)
• yarn 1.12.3
• npm v3.5.2
• node v8.10.0
• zsh 5.4.2

Steps

1. Confirm your global bin path

   yarn global bin
   

I got: /home/username/.yarn/bin

2. set yarn prefix:

   make sure your yarn prefix is the parent directory of your bin directory. You can confirm by running

   yarn config get prefix
   

   when I ran this, my prefix was empty, so I set it:

   yarn config set prefix ~/.yarn
   

3. add the following to ~/.bash_profile or ~/.bashrc

   export PATH="$PATH:`yarn global bin`"
   

   for zsh users, be sure to add this line to ~/.zshrc

4. restart your shell or start a new one

   bash -l or zsh

You should add export PATH="$PATH:$(yarn global bin)" to your ~/.bash_profile or whatever you use. It would solve the issue.

Depending on how you installed it, Yarn's global folder varies for some reason. You can follow this issue here.
