Question

我正在尝试在Windows计算机上安装Chromium。我正在密切关注来自Chromium项目站点的instructions链接。我尝试运行命令'This doesn't effect anything that stored a reference to it. Set TestClass = Nothing 'Make a call on the default to force it to reinstantiate. Debug.Print TestClass.IsDefaultInstance 'This will now be false. Debug.Print foo(5).IsDefaultInstance，但收到以下错误消息（某些路径已匿名）：

gn gen out/Default

看一下setup_toolchain.py的来源（错误发生的地方），我认为问题出在以下几行：

Traceback (most recent call last):

添加一些打印语句后，似乎循环正在检查以下路径是否存在：

for path in env['LIB'].split(';'):
  if os.path.exists(os.path.join(path, 'User32.Lib')):
    vc_lib_um_path = os.path.realpath(path)
    break

这些路径都不存在。我对Windows，Visual Studio或C的了解并不十分了解，无法知道User32.Lib的含义。 Visual Studio应该在某处添加了它吗？或者，当我安装Windows 10 SDK时，是否应该在某处生成文件？有什么我可以解决的问题吗？

我正在努力找出可能出问题并导致此问题的原因，我们将不胜感激。

看起来像GN找不到所需的运行时要求。脚本对此有些脆弱。就我而言，我安装了Visual 2017和2019，就会发生此问题。因此，我卸载了Visual 2019并运行良好。重新验证运行时规范（SDK，VS版本，路径等）。 https://bitbucket.org/chromiumembedded/cef/wiki/MasterBuildQuickStart.md#markdown-header-windows-setup
