Visual Studio，Python，命令“python setup.py egg_info”失败，错误代码1在C：\ Users \ ... \ AppData \ Local \ Temp \ pip-install-953alcay \ rpy2 \

Question

我试图在Python 3.6中的Visual Studio Professional 2017版本15.8.2中安装rpy2，我得到下面看到的egg_info错误。

我已经搜索了类似的问题并且没有运气地遵循他们的建议

• 我以管理员身份运行Visual Studio
• 我确保pip（版本18.0）和setuptools（版本40.2.0）是最新的

我正在运行Windows 10并且没有想法

Answer 1

Windows没有sh命令，你只需要安装类似Cygwin的东西来解决这个问题
