I have same issue. What was the resolution?

I have the same issue, I couldn't uninstall yarn. I'm running Ubuntu 16.04.
I fixed it this way:
1- Run which yarn to find out the package behind the yarn command.
2- It turned out to be usr/bin/yarn.
3- I uninstalled the yarn command unistalling cmdtest, with sudo apt-get purge cmdtest as suggested here: #3189.
It seems there's also a conflict with Hadoop yarn, reported here: https://superuser.com/questions/1193406/hadoop-yarn-yarn-npm-name-conflict.
Hope this helps.

I ran which yarn which gave me the path: usr/bin/yarn. I went in and deleted yarn by: sudo rm yarn. Then reinstalled it with: sudo npm install --global yarn. Which worked for me

ah, you need to use where.exe yarn in Windows Powershell
I really despise powershell
