Can this tool be installed during the build?

yes

1. use this action somewhere in the build process https://github.com/marketplace/actions/setup-pnpm
2. its added to the path, so you can use it as if you did a npm global install (can run pnpm install for example)

Tool installation time in runtime

~3-5 seconds

Are you willing to submit a PR?

not completely sure how the runner works so I'll have to take a look around in the repo, but I'm willing to PR

Hi @autumnblazey,
given the small installation time in runtime and the existence of action with a wider functionality where you can select which version you want to use, we'd prefer not to pre-install this tool on images.
Usage of action is more safe and reliable way to install and use any tool that will guarantee that your workflow won't be broken with unexpected tool upgrade.

I am closing this issue. Please, feel free to create a new one in case if any other help is needed.

edit: fixed! I believe pnpm/[email protected] contains the fix so use that or later

FYI to anyone who finds this, the action hasn't had any updates since after the add-path command was deprecated and disabled, so a workaround (for now at least) is to use the setup node action (it doesnt work without using this, i've tried), then running npm i -g pnpm@version

steps:
- name: Setup Node.js environment
  uses: actions/[email protected]
  with:
    node-version: "15"

- name: install pnpm
  run: npm i -g pnpm

Once actions/setup-node#482 is merged, you can use corepack instead

that would be nice, thanks for the heads up!
