[Bug] Unable to switch from yarn 2 to yarn 1

[ghost]

I've uninstalled yarn 2 via sudo npm uninstall -g yarn. Running yarn -v returns bash: /usr/bin/yarn: No such file or directory.

So far, so good. Then I ran sudo npm install -g '[email protected]':

$ sudo npm install -g '[email protected]'
/usr/bin/yarnpkg -> /usr/lib/node_modules/yarn/bin/yarn.js
/usr/bin/yarn -> /usr/lib/node_modules/yarn/bin/yarn.js
+ [email protected]

but whenever I run yarn -v it gives me 2.4.1.

What am I doing wrong?

You need to revert the actions done by yarn set version ...

Unfortunately this didn't work.

$ yarn set version 1.22.5
➤ YN0000: Downloading https://github.com/yarnpkg/yarn/releases/download/v1.22.5/yarn-1.22.5.js
➤ YN0000: Saving the new release in .yarn/releases/yarn-1.22.5.cjs
➤ YN0000: Done in 1s 436ms

But yarn -v still returns 2.4.1, even though I've closed and reopened the terminal.

Solved. Besides running sudo npm uninstall -g yarn, I've also ran:
sudo apt remove yarn && sudo apt purge yarn
and
sudo rm -rf /usr/local/bin/yarn && sudo rm -rf /usr/local/bin/yarn.lock
Then I reinstalled it with sudo npm install -g '[email protected]' and ran yarn set version 1.22.5 in my project folder.
