如何在使用 GitHub Actions for macOS 进行测试之前安装 X11?

How to install X11 before testing with GitHub Actions for macOS?

我正在使用 GitHub 操作测试 R 包,它在 Windows 和 Linux 上成功。

但是,它在 Mac OS 上失败了,正如您在 logs:

上看到的
  Warning in grSoftVersion() :
    unable to load shared object '/Library/Frameworks/R.framework/Resources/modules//R_X11.so':
    dlopen(/Library/Frameworks/R.framework/Resources/modules//R_X11.so, 6): Library not loaded: /opt/X11/lib/libSM.6.dylib
    Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/modules/R_X11.so
    Reason: image not found
  Warning in cairoVersion() :

    Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/grDevices/libs/cairo.so
    Reason: image not found
  Warning in png(filename = file, width = width, height = height, units = "in",  :

    src must be a string starting with 'rId' or an image filename
  Calls: %>% ... <Anonymous> -> body_add_gg -> body_add_img -> external_img
  Execution halted

我没有 Mac 电脑,以后不打算这样做,所以我无法自己测试。

正如我在 上看到的,这可能是由于测试机器上没有安装 X11。

如何告诉 GitHub Actions 此代码依赖于 X11?

编辑:

这是我的 GitHub 操作配置文件:link。添加此代码解决了问题:

  - name: Install X11 dependencies on MacOS
    if: runner.os == 'macOS'
    run: |
      brew --cask install xquartz

Homebrew 在 GitHub Actions 默认 VM 上,

https://github.com/actions/virtual-environments/blob/main/images/macos/macos-10.15-Readme.md

因此您可以使用

通过自制软件安装 X11
brew cask install xquartz

https://formulae.brew.sh/cask/xquartz

在执行 R 测试之前。

对我有用的是将其添加到工作流文件中:

      - name: Install XQuartz on macOS
        if: runner.os == 'macOS'
        run: brew install xquartz --cask

我找到了这个信息 here, and adapted it using this 评论(因为原始代码不起作用,所以出错了)。
