我正在尝试安装该软件包rpy2将 R 与 Python 结合使用。但是使用 pip install 安装失败。
我在 Windows 10 上将 R 和 Python 与 Microsoft Visual Studio 2017 结合使用。安装了适用于 Visual Studio 的 R 和 Python 工具。我尝试安装rpy2使用 python 环境从 Visual Studio 中。但它失败了。
我也下载了rpy2-2.9.5-cp37-cp37m-win_amd64.whl from lfd.uci.edu https://www.lfd.uci.edu/~gohlke/pythonlibs/并尝试使用 cmd 安装它pip install它也失败了。
我也设置了R-Home指向我的 R 安装的 R 二进制文件的变量。
我尝试过的命令：pip install rpy2（在视觉工作室中）
pip install rpy2-2.9.5-cp37-cp37m-win_amd64.whl（使用cmd）
安装时出现如下错误信息rpy2在 Visual Studio 2017 中：

使用 cmd 安装 whl 文件时也会出现此消息。
为什么会出现此消息以及如何安装rpy2Windows 10 上没有任何错误吗？
感谢您的帮助。
