在Windows 10上安装rpy2时出错

Question

在我的计算机上使用pip to install rpy2时出现此错误：

C:\Python27\Scripts>pip install rpy2
Collecting rpy2
  Using cached rpy2-2.8.2.tar.gz
    Complete output from command python setup.py egg_info:
    Warning: Tried to guess R's HOME but no command (R) in the PATH.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\isaac\appdata\local\temp\pip-build-_n5cg0\rpy2\

我认为这只是我计算机上R目录的错误。如何在pip上指明正确的目录？
