GitHub 操作无法安装 gem

Question

我有以下 GitHub 操作：

name: Rubocop
on: push

jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - name: Install Rubocop
        run: gem install rubocop
      - name: Rubocop
        run: rubocop

当此操作运行时，我收到以下错误：

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.5.0 directory.

我该如何解决这个问题？

Answer 1

按照official GitHub Actions docs使用以下内容：

name: Linting

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: ruby/setup-ruby@v1
      with:
        ruby-version: 2.6
    - run: bundle install
    - name: Rubocop
      run: rubocop

或者如果你没有gemfile:

name: Linting

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: ruby/setup-ruby@v1
      with:
        ruby-version: 2.6
    - run: gem install rubocop
    - name: Rubocop
      run: rubocop

sudo gem install rubocop 是You don't have write permissions for the /var/lib/gems/2.3.0 directory 中描述的另一个选项
