背景：gitee上下载的开源vue项目，本地部署。执行【npm install】时，报错Error: Can't find Python executable "python", you can set the PYTHON env variable。
解决：
网上提供的一个解决办法：管理员身份打开cmd 键入【npm install --global --production windows-build-tools】。但是这行命令执行一半不动了，再去执行【npm install】时出现另一个问题error MSB4019: 未找到导入的项目“E:Microsoft.Cpp.Default.props”，最后参考https://github.com/felixrieseberg/windows-build-tools/issues/175解决了问题！
// 这里执行npm install -g --production windows-build-tools其实没有成功的

//需要执行配置 C:Windowssystem32>npm config set msvs_version 2017 C:Windowssystem32>
注意：可能还是不能找到python，去看一下环境变量Path，有没有python27的配置，没有的话需要添加C:Usersadmin.windows-build-toolspython27
//再去执行 npm install, 成功了!
