Dynamic .NPMRC not being reloaded for preinstall

[sirshurak]

Yarn: v1.22.18
Terminal: PowerShell or Git Bash

Using AWS CodeArtifact to install some private components are getting not found because npmrc dynamic generated in preinstall is not being reloaded on install.

To reproduce: just create a dynamic .npmrc file on script preinstall, then call yarn install, yarn will throw 401 not found.

I have the same issue on mac/linux. However, the next yarn install will work properly.

I added this as my preinstall script

Where the code to login is in the preinstall.js file. Could use the AWS CLI command too.

"preinstall": "node preinstall.js && yarn install --ignore-scripts && yarn postinstall && exit 0"

I faced the same issue. I printed the configuration using yarn config list during the preinstall stage, and everything appeared to be okay! It was very difficult to pinpoint the problem.
Also, yarn's generic 401 error message confused me and led me to many online discussions about token issues with the yarn.lock file.
