[Bug] Can't switch back to Yarn v1 after trying out Yarn v2

• I’d be willing to implement a fix

Describe the bug

I wanted to try out Yarn v2, so I did yarn set version 2. This worked. But now I can’t switch back to v1:

> yarn set version 1
^[➤ YN0000: Selecting the highest release amongst 1.22.0 and 18 others
➤ YN0000: Downloading https://github.com/yarnpkg/yarn/releases/download/v1.22.0/yarn-1.22.0.js
➤ YN0000: Saving the new release in .yarn/releases/yarn-1.22.0.js
➤ YN0000: Done in 2.35s

> yarn -v
2.0.0-rc.29

To Reproduce

1. Start with a regular Yarn 1 installation on macOS, installed via brew.
2. Run yarn set version 2

• Running yarn -v now prints 2.0.0-rc.29.

1. Run yarn set version 1

• The output makes it look like this worked, but it didn’t – yarn -v still prints 2.0.0-rc.29.

Environment if relevant (please complete the following information):

• OS: macOS
• Node version: v12.13.0
• Yarn version: 2.0.0-rc.29

Additional context

Sorry if I’m missing something obvious - I don’t know much about Berry/Yarn 2, I just wanted to try it out, and now I can’t get back to Yarn 1.

I “fixed” it my going into my users root directory and executing yarn set version ^1. Now it’s globally back to v1

i had a default in my root, deleting it did the trick

cat ~/.yarnrc.yml 
> yarnPath: ".yarn/releases/yarn-berry.cjs"

rm -f ~/.yarnrc.yml

npm install -g 'yarn@1.22.1'

yarn -v
> 1.22.10
