ERROR Error: Command failed: npx yarn --prod

This is a placeholder issue meant to provide instructions for anyone who encounters this error during the build-tools self-update process.

When build-tools updates itself, it first does a git pull and then a yarn install. Unfortunately, with our recent migration to Yarn 4 this causes an issue, because the old code runs npx yarn --prod, which in this case causes the following error:

Running "npx yarn --prod" in C:\Users\itsananderson\.electron_build_tools

This happens because Yarn 4 does not accept a --prod parameter. After the upgrade, the new build-tools code instead runs yarn install --immutable which is supported by Yarn 4.

To fix this error, you can use the following commands to manually run the Yarn install:

cd ~/.electron_build_tools
yarn install --immutable

Quick note if anyone else runs into it. My yarn install --immutable failed with:

PS C:\Users\nikwen\.electron_build_tools> yarn install --immutable

The solution was:

pip install setuptools
