首先，我运行下一个命令：
python tools/dev/v8gen.py x64.release.sample
所有GN文件生成成功。之后我运行以下命令：
ninja -C out.gn/x64.release.sample v8_monolith
经过几分钟的编译，我收到了很多编译错误：

是什么原因导致了这个问题？如何解决？
我遇到了同样的问题，我这样解决了：
- 下载visual studio 2019安装程序，并安装vs2019，请注意，无需检查Windows SDK项目，因为这不是重点，也无需重新安装/添加新版本的Windows SDK。而且，vs2019可能与vs2022同时存在
- 切换到vs2019编译环境：打开一个新的Windows终端选项卡，执行命令：
> set vs2019_install=[path to your Microsoft Visual Studio2019Community]
> set WINDOWSSDKDIR=[path to your Windows Kits10]
> set DEPOT_TOOLS_WIN_TOOLCHAIN=0
> gclient sync
- 好的，你现在可以用vs2019构建v8了：
> python toolsdevgm.py x64.release
希望这能有所帮助。
