找不到ALSA-github操作單元測驗，正確設定env/envvars

我的 .github/workflows 檔案夾中有以下 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 

當我進行 PR 時，它會運行測驗......但是它們在 github 中失敗，而不是在我的本地機器上。

錯誤如下：

通讀一遍-看起來罪魁禍首是我們實際上并不存在的音頻驅動程式

    runs-on: ubuntu-latest

不包括音頻驅動程式？

我嘗試將以下內容添加到 yaml 檔案中（直接在該運行檔案的下方）

    env:
      SDL_AUDIODRIVER: 'ALSA'

這也不起作用 - 并產生相同的錯誤。

那么如何讓 GitHub 中的容器擁有正確的音頻驅動程式？

uj5u.com熱心網友回復：

github 操作計算機沒有任何揚聲器可以輸出音頻，也沒有顯示幕可以輸出視頻。這是一個無頭系統。

解決方案是設定

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