我用Google搜索了许多相关问题，因为我是离子学的初学者而迷失了。
我的npm版本：6.1.0
我的nodejs版本：10.5.0
我克隆了一个私人仓库，我要做的第一件事是npm i安装软件包。
然后我到达这里时遇到错误：
> grpc@1.10.0 install D:\Projects\...\the-project\node_modules\grpc
> node-pre-gyp install --fallback-to-build --library=static_library
然后抛出了一堆错误：

我已经Google搜索并检查了许多github / stackoverflow帖子，但是我仍然迷失在中间，因为所有解决方案都不一样，而且我也不明白它的用途。
因此，我需要帮助您，请告知我该怎么做。
到目前为止，我所做的是：
1）npm install --msvs_version=2013 -g node-inspector：错误
2）npm config set msvs_version 2013：没有结果
3）node-pre-gyp install --fallback-to-build：错误'node-pre-gyp' is not recognized as an internal or external command,
operable program or batch file.
答案 0 :(得分：0)
错误表明未找到python。
gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable。
因此，您应该安装它（版本2.7）并将其添加到系统变量中。
