yarn global list
The command had issue in Spring 2017, that had been fixed.
2017 workaround
Currently I directly list Yarn global packages folder content:
- Windows:
%LOCALAPPDATA%/Yarn/config/global - OSX and Linux non-root:
~/.config/yarn/global - Linux if logged in as root:
/usr/local/share/.config/yarn/global
Update June 22, 2020
As of May 12, 2017 this problem has been resolved. See issue and pull request.
So you can use yarn global list to list all globally installed packages.
