windows中怎么安装patch？

Question

在cmd命令行执行一个命令的时候，出现/usr/bin/bash: patch: command not found，windows中怎么安装patch这个东西？具体错误如下：

https://docs.bazel.build/vers...

官方文档提到了，预装依赖有MSYS2，这个其实就是一个posix模拟环境，类似于mingw32和Cygwin，里面带有patch命令。

https://docs.bazel.build/vers...

这个文档也提到了如果不在MSYS2 shell下运行，应该要配置环境变量。

题主的问题都是不仔细阅读官方文档所致。建议先通读官方文档再说。
