在Windows 7，Python 3.3上安装RPy2-2.3.8时出错

Question

人。 我正在尝试在 Windows 7 （64位）， Python 3.3 上安装 RPy2-2.3.8 ，但是 RPy2 < / strong>似乎有很多安装问题...... :(

我尝试通过在＆＃34; cmd＆＃34;上键入＆＃34; python.exe setup.py install＆＃34; 来安装RPy2在Windows环境中。

R版3.0.2已成功安装，其路径已添加到环境变量中。

但是，发生以下错误。任何人都能说出这个错误是什么意思吗？

**D:\>cd rpy2-2.3.8**

D:\rpy2-2.3.8>c:\Python33\python.exe setup.py install

对我而言，它特别奇怪，因为错误是＆＃34; TypeError。＆＃34; 另外，所有警告意味着什么？

各种讨论将不胜感激。

非常感谢。

RPy不支持Python 3.x.你必须使用2.5＆lt; = Python＆lt; 3.0。有关详细信息，请参阅official documentation。
