在 windows 上安装 rpy2

Question

我正在尝试在机器上安装 rpy2 运行 Windows 10. 我已经安装了 R 3.4.4（64 位）并且它在 RGui 中运行良好。然后我尝试 pip install rpy2，但出现找不到 R 的错误，因此我将 c:\Program Files\R\R-3.4.4\bin\ 添加到我的路径环境变量中。现在我做的时候

pip install rpy2

我得到一个不同的错误：

Command '('c:\PROGRA~1\R\R-34~1.4\bin\x64\R', 'CMD', 'config', '--ldflags')' returned non-zero exit status 1

完整输出如下。知道我做错了什么吗？

pip install rpy2

输出包含错误：

'sh' is not recognized as an internal or external command

但我认为这只是一个警告（因为它后面有输出）。 sh (shell) 是 Nix 特定的并且（自然地）不存在于赢。但是，如果您为 Win 或 Lnx env 模拟器安装端口（例如 Cygwin)，它可能会起作用。

这是 [ReadTheDocs.rpy2]: Installation 的内容（其中包含“在 Linux 上编译”和“在 OS 上编译 X”部分，但与 Win 无关，尽管它提到它应该编译成功）指出：

There is currently no binaries or support for Microsoft Windows (more for lack of resources than anything else).
Microsoft’s Windows - unofficial and unsupported binaries are provided by Christoph Gohlke (http://www.lfd.uci.edu/~gohlke/pythonlibs); there is otherwise currently close to no support for this platform

添加@pyguy 采取的步骤（来自评论），以便成功安装 rpy2:

从 [=17= 下载 rpy2‑2.9.3‑cp35‑cp35m‑win_amd64.whl（或可能同时添加的任何更新版本） ]（对于32位，下载*win32.whl）
在.whl[=63=中打开一个cmdwindow（作为管理员） ]的下载目录

将R_USERenv var设置为当前用户名：set R_USER=%USERNAME%

python -m pip install rpy2‑2.9.3‑cp35‑cp35m‑win_amd64.whl（Python的（二进制）dir必须在 %PATH%，或指定完整路径)
