gn args out\Debug_GN_x86 用来配置编译参数，执行gn args out\Release_GN_x86时异常：

Toolchain is out of date. Run "gclient runhooks" to update the toolchain, or set DEPOT_TOOLS_WIN_TOOLCHAIN=0 to use the locally installed toolchain.

 

 

解决方案：

先执行set DEPOT_TOOLS_WIN_TOOLCHAIN=0，使用本地安装的工具链

然后再执行gn args out\Release_GN_x86
