Not working locally with act

[klarkc]

I am trying to simulate the workflow locally with act, but I am getting this error:

[CI/build]   💬  ::debug::finished caching tool
| Cached path /opt/hostedtoolcache/spago/0.20.9/x64, adding to PATH
| Fetching psa
| [command]/usr/bin/sudo npm install -g purescript-psa@0.8.2
| sudo: npm: command not found

I tried the default config, and even adding

      - uses: actions/setup-node@v3
        with:
          node-version: latest
          cache: 'npm'

before uses: purescript-contrib/setup-purescript@main it still happens.

I haven’t used act before so I’m not sure how to solve this. We use NPM because GitHub’s runners have node by default, and therefore npm; if act doesn’t have that, then you’ll have to install it somehow

[klarkc]

I have no idea why, but this works:

name: CI

on:
  push:
    branches: [master]
  pull_request:
    branches: [master]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - uses: actions/setup-node@v3
        with:
          node-version: latest
          cache: 'npm'

      - run: npm install -g bats
      - run: bats -v

The only difference is the missing sudo 🤔 there is a reason for the sudo?

[thomashoneyman]

I can't remember why the sudo is there, although the explicit case statement on Windows vs. non-Windows makes me suspicious that there is a reason for it. I'm happy to remove it if it is not necessary.

[klarkc]

Yeah, 32fa32c adds the code block /src/Setup/GetTool.purs, but it's interesting to see that on Windows it uses npm without sudo. I'll try to change it and see what happens in a real linux runner.

I encountered the same issue. I was trying to be a good citizen and run github action with act before opening a PR.
At the same time I'm wondering if this isn't more of an issue of act rather than this action. act is supposed to behave the same way a github runner would.

@klarkc Did you find something out regarding sudo?

Nop. I'm guessing here, but I believe the origin of the bug is npm not being installed by default. Even so, the action should not rely in this npm. Because people normally use actions/setup-node which patches the user environment, and not the embeded npm. It hides a potential bug by using unexpected npm versions.
