谷歌奥马哈构建错误

Question

当我尝试在 Windows 10 机器上构建 omaha 时，我收到了一些警告和致命错误。

我花了很多时间调试警告，似乎 scons 1.3.1 不支持 Visual Studio 2015，但是 google 的构建 instructions 暗示相反。此外，还不清楚错误是否取决于警告。请帮忙解决问题。

Answer 1

我解决了这个问题，结果发现新版本的 wix 工具集有 bin 文件夹，其中包含所有 utils 和官方文档和教程包含错误的环境变量。顺便说一句，警告对构建过程完全没有影响。 所以可能类似情况下调试任何代码都没有意义，只需要检查环境即可。
