使用easy_install在Python中安装rpy2模块时出错

我一直在尝试安装rpy 2模块，这样我就可以在Python脚本中使用R函数，但在遵循这些页面的建议后，我收到了一个错误：

1）Tried to guess R's HOME but no R command in the PATH. OsX 10.6
2）http://rpy.sourceforge.net/rpy2/doc-dev/html/overview.html

到目前为止我所做的：

**1）**修改了我的路径环境变量，将“C：\Program Files\R\R-3.1.0\bin\x64;”
**2）**创建一个新的环境变量“R_HOME”，并将其值设置为“C：\Program Files\R\R-3.1.0”
**3）**创建了一个名为“R_USER”的新环境变量，并将其值设置为“Hefin”（我的Windows用户名）

然后在命令提示符下键入：

easy_install rpy2

据我所知，easy_install是正确安装的。
我得到的输出是：

对不起，这太冗长了！如果我调用python并尝试导入rpy模块，我会得到：

>>> import python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'python'
>>>

恐怕我是Python的新手，我不知道我做错了什么。我已经搜索了以前的论坛帖子，但似乎没有一个有这个问题。我使用的是64位机器，Windows 7，Python3.4和R3.1.0。
任何帮助或想法将不胜感激，因为我相信这只是一些简单的我做错了。
谢谢大家！

有一种更简单的方法可以做到这一点-从Christoph Gohlke的Python Extension Packages for Windows存储库中安装rpy2。

pip install rpy2‑2.5.5‑cp34‑none‑win_amd64.whl

pip已经包含在Python 3.4中，在安装新模块时应该使用它来代替easy_install，因为easy_install已被弃用。

在windows上安装rpy2是直接使用conda

conda install rpy2
