The team has found a solution for the issue in the short term. It's discussed here: https://github.com/netlify/cli/issues/3788#issuecomment-990914667.

In the long term, the team will continue to work on a solution without this workaround.

The team is working on a fix for the issue.

We're continuing to investigate this issue.

We've identified an issue where netlify-cli is not being installed when using yarn. This appears to be an issue with yarn at the moment. While we investigate further, the workaround is to use npm.
