我正在尝试在运行Windows 10的计算机上安装rpy2。我已经安装了R 3.4.4(64位),它在RGui中工作正常。然后我尝试pip安装rpy2,但是收到了一个无法找到R的错误,所以我将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
我得到了一个不同的错误:
命令'('c:\ PROGRA~1 \ R \ R-34~1.4 \ bin \ x64 \ R','CMD','config',' - oldflags')'返回非零退出状态1
完整输出如下。知道我做错了吗?
pip install rpy2

答案 0 :(得分:2)
是的,您的输出包含错误:
'sh'未被识别为内部或外部命令
但我认为这只是一个警告(因为它后面有输出)。 sh 是 Ux 特定的( shell )并且(自然地) Win 上不存在。但是,如果为 Win 或 Lnx env模拟器(如Cygwin)安装端口,则可能会有效。
以下是[ReadTheDocs.rpy2]: Installation(其中“在Linux上编译”和“在OS X上编译”部分,但没有关于 Win ,虽然它提到它应该成功编译)状态:
目前没有Microsoft Windows的二进制文件或支持(更多是因为缺少资源而不是其他任何内容)。
微软的Windows - 非官方和不受支持的二进制文件由Christoph Gohlke(http://www.lfd.uci.edu/~gohlke/pythonlibs)提供;否则目前几乎不支持这个平台

添加@pyguy采取的步骤(来自评论),以便成功安装 rpy2 :
set R_USER=%USERNAME%
pip install rpy2‑2.9.3‑cp35‑cp35m‑win_amd64.whl
( pip 的目录必须在%PATH%中)
