使用easy_install在Python中安装rpy2模块时出错

I've been trying to install the rpy2 module so I can use R functions inside my Python script, but I'm getting an error after following the advice from these pages:

我一直在尝试安装rpy2模块，这样我就可以在Python脚本中使用R函数了，但是在遵循了这些页面的建议之后，我得到了一个错误:

1) Tried to guess R's HOME but no R command in the PATH. OsX 10.6

1)尝试猜测R的家，但是路径中没有R命令。OsX 10.6

2) http://rpy.sourceforge.net/rpy2/doc-dev/html/overview.html

What I've done so far:

到目前为止我所做的:

1) Edited my path environment variable to include "C:\Program Files\R\R-3.1.0\bin\x64;"

1)编辑了我的path环境变量，其中包含“C:\程序文件\R\R-3.1.0\bin\ bin\ \bin\x64”;

2) Created a new environment variable called "R_HOME" and set its value to "C:\Program Files\R\R-3.1.0"

2)创建了一个名为“R_HOME”的新环境变量，并将其值设置为“C:\程序文件\R-3.1.0”

3) Created a new environment variable called "R_USER" and set its value to "Hefin" (my windows username)

3)创建一个名为“R_USER”的新环境变量，并将其值设置为“Hefin”(我的windows用户名)

Then in my command prompt I type:

然后在命令提示符中输入:

easy_install rpy2

As far as I'm aware, easy_install is setup and installed correctly.

据我所知，easy_install安装和安装都是正确的。

The output I get is:

Sorry it's so verbose! If I then invoke python and try to import the rpy module, I get:

对不起这么详细!如果我然后调用python并尝试导入rpy模块，我得到:

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

I'm afraid I'm new to Python and I don't know what I'm doing wrong. I've searched through previous forum posts, but none seem to have this problem. I'm using a 64bit machine with Windows 7, Python3.4 and R3.1.0.

我恐怕是Python的新手，我不知道我做错了什么。我搜索过以前的论坛帖子，但似乎没有一个人有这个问题。我使用的是一台64位的机器，有Windows 7、Python3.4和R3.1.0。

Any help or thoughts would be much appreciated as I'm sure it's just something simple I'm doing wrong.

任何帮助或想法都将非常感谢，因为我确信这只是我做错的简单事情。

Thank you!

谢谢你！

There's a much easier way to go about this - install rpy2 from Christoph Gohlke's Python Extension Packages for Windows repository here. Download the rpy2‑2.5.5‑cp34‑none‑win_amd64.whl file (the current version at the time of this writing), change to the download folder on the command line, and run

有一种更简单的方法来实现这一点——在这里为Windows存储库安装Christoph Gohlke的Python扩展包rpy2。下载rpy2 2.5.5——cp34 - - win_amd64。whl文件(撰写本文时的当前版本)，切换到命令行上的下载文件夹，然后运行。

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

pip is already included in Python 3.4, and should be used instead of easy_install when installing new modules, as easy_install is deprecated.

Python 3.4中已经包含pip，在安装新模块时应该使用pip而不是easy_install，因为easy_install是不赞成使用的。
