Using elm-test in a git hub action

I want to use the an git hub action to test and build my elm package whenever a commit is pushed to the master branch for this my action .yml file looks like this

name: CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup Elm environment
      uses: JorelAli/setup-elm@v1
      with:
        # Version of Elm to use. E.g. 0.19.1
        elm-version: 0.19.1
    - run: |
        sudo npm install -g elm-test # this fails
        elm-test
        elm make

for testing I want to use elm-test which can be installed via npm but the command sudo npm install -g elm-test fails with

/usr/local/bin/elm-test -> /usr/local/lib/node_modules/elm-test/bin/elm-test

> [email protected] install /usr/local/lib/node_modules/elm-test/node_modules/elmi-to-json
> binwrap-install

Any advice on how to install elm-test inside a git hub action?

Edit: Without the sudo the error becomes

Solution

  • Thanks to @toastal comment I found another solution. That is to set up a package.json file using npm and then adding elm-test as a dependency with the command

    npm install -D elm-test

    also you might want to add node_modules to your .gitignore to ignore npms installation folder.

    Then in the yml file you can just run the command npm install and elm-test gets installed. Then you can call it with

    ./node_modules/elm-test/bin/elm-test

    My yml file now looks like this

    name: Tests

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup Elm environment
      uses: JorelAli/setup-elm@v1
      with:
        # Version of Elm to use. E.g. 0.19.1
        elm-version: 0.19.1
    - name: install npm dependencies
      run: npm install
    - name: Test
      run: ./node_modules/elm-test/bin/elm-test
    - name: check documentation
      run: |
        elm make --docs=docs.json
        rm docs.json
