Thank you for confirming that using pnpm install libs --save are fine. I wasn’t clear about it earlier
I did try that and it still didn’t work. I think writing in package.json will ensure I don’t need to do pnpm install again and again.
I saw the following description from https://www.npmjs.com/package/fs:
This package name is not currently in use, but was formerly occupied by another package. To avoid malicious use, npm is hanging on to the package name, but loosely, and we'll probably give it to you if you want it.
I believe glitch staff needs to know about this?
