问题描述

我正在尝试在运行 Windows 10 的机器上安装 rpy2.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，但收到找不到 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.现在当我这样做

pip install rpy2

我收到一个不同的错误:

Command '('c:\PROGRA~1\R\R-34~1.4\bin\x64\R', 'CMD', 'config', '--ldflags')' 返回非零退出状态1

完整的输出如下.知道我做错了什么吗?

解决方案

输出包含错误:

'sh' 不被识别为内部或外部命令

但我认为这只是一个警告(因为后面有输出).sh (shell) 是 Nix 特定的，并且(自然地)在 Win 上不存在.但是，如果您为 Win 安装了端口，或者 Lnx env 模拟器(例如 Cygwin)，它可能会工作.

以下是[ReadTheDocs.rpy2]:安装(其中包含在 Linux 上编译"和在 OS X 上编译"部分，但没有关于 Win，尽管它提到它应该编译成功)状态:

目前没有对 Microsoft Windows 的二进制文件或支持(更多是因为缺乏资源而不是其他任何东西).
Microsoft 的 Windows - 非官方和不受支持的二进制文件由 Christoph Gohlke 提供 (http://www.lfd.uci.edu/~gohlke/pythonlibs);否则目前几乎不支持此平台

添加@pyguy 采取的步骤(来自评论)，以便成功安装 rpy2:

从 (32 位，下载*win32.whl)
在.whl的下载目录cmd窗口(作为管理员)>
将 R_USER env 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%中，或者指定完整路径)

I am trying to install rpy2 on a machine running Windows 10. I have already installed R 3.4.4 (64bit) and it works fine in RGui. I then tried to pip install rpy2, but was getting an error that it couldn't find R, so I added c:\Program Files\R\R-3.4.4\bin\ to my path environment variable. Now when I do

pip install rpy2

I get a different error:

The full output is given below. Any idea what I am doing wrong?

解决方案

The output contains the error:

but I thought it was only a warning (as there was output coming after it).sh (shell) is Nix specific and (naturally) doesn't exist on Win. However, if you install a port for Win, or an Lnx env emulator (like Cygwin), it might work.

Here's what [ReadTheDocs.rpy2]: Installation (which has "Compiling on Linux" and "Compiling on OS X" sections, but nothing about Win, although it mentions that it should compile successfully) states:

Update #0

Adding steps that @pyguy took (from comment), in order to successfully install rpy2:

Download rpy2‑2.9.3‑cp35‑cp35m‑win_amd64.whl (or any newer version that might have been added in the meantime) from [UCI.LFD]: Unofficial Windows Binaries for Python Extension Packages (for 32bit, download the *win32.whl)
Open a cmd window (as Administrator) in the .whl's download dir
Set R_USER env var to current username: set R_USER=%USERNAME%
python -m pip install rpy2‑2.9.3‑cp35‑cp35m‑win_amd64.whl (Python's (binary) dir must be in %PATH%, or specify the full path)
