解决方法

我的python版本是:

• windows10
• 3.6
• 64位

我下载的版本为:

使用pip install 安装whl文件

首先将下载文件放到当前文件夹下, 然后运行下面命令:
代码

pip install rpy2-2.9.4-cp36-cp36m-win_amd64.whl

结果

$ pip install rpy2-2.9.4-cp36-cp36m-win_amd64.whl

测试

# Example 1
import rpy2.robjects as robjects
pi = robjects.r('pi')
pi[0]

结果

>>> import rpy2.robjects as robjects
>>> pi = robjects.r('pi')
>>> pi[0]
3.141592653589793

搞定.
