未找到 ALSA - github 动作单元测试，正确设置 env/envvars

Question

我的 .github/workflows 文件夹中有以下 yaml。

name: Run Python Tests
on:
  push:
    branches:
      - main

  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["2.7", "3.6", "3.7", "3.8", "3.9"]
    steps:
      - uses: actions/checkout@v3
      - name: Install Python ${{ matrix.python-version }}
        uses: actions/setup-python@v3
        with:
          python-version: ${{ matrix.python-version }}
      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          pip install -r requirements.txt
      - name: Run tests with unittest 
        run: python -m unittest test.py

当我创建 PR 时，它运行测试...但是它们在 github 而不是在我的本地机器上失败。

错误如下：

仔细阅读 - 看起来罪魁祸首是当我们

时实际上并不存在的音频驱动程序

    runs-on: ubuntu-latest

不包括音频驱动程序？

我已经尝试将以下内容添加到 yaml 文件中（直接在运行时下方）


    env:
      SDL_AUDIODRIVER: 'ALSA'

这也不起作用 - 并产生相同的错误。

那么如何让 GitHub 中的容器拥有正确的音频驱动程序？

Answer 1

A github actions 计算机没有任何扬声器可以输出音频，也没有显示器可以输出视频。这是一个无头系统。

解决方法是设置

    env:
      SDL_VIDEODRIVER: "dummy"
      SDL_AUDIODRIVER: "disk"
