我在 Windows 7 上运行 Python 2.7。首先，我安装了 R 和 RTools，并更改了以下环境变量：

RHOME: C:\Program Files\R\R-2.15.2
R_HOME: C:\Program Files\R\R-2.15.2
R_USER: C:\Users\username\Documents

并将以下目录附加到 PATH：

C:\Program Files\R\R-2.15.\bin\i386; C:\Rtools\bin

接下来，我在这里通过二进制可执行文件安装了 RPy2。

通过 Python 运行 RPY2 时，出现以下错误：

Traceback (most recent call last):
  File "<string>", line 254, in run_nodebug
  File "C:\Python27\blaise automation.py", line 14, in <module>
    import rpy2.robjects as robjects
  File "C:\Python27\lib\site-packages\rpy2\robjects\__init__.py", line 14, in <module>
    import rpy2.rinterface as rinterface
  File "C:\Python27\lib\site-packages\rpy2\rinterface\__init__.py", line 28, in <module>
    "or install the win32 package.")
RuntimeError: No environment variable R_HOME could be found, calling the command 'R RHOME' does not return anything, and unable to import win32api or win32con, both of which being needed to retrieve where is R from the registry. You should either specify R_HOME or install the win32 package.

我已经为此工作了几个小时。有谁知道如何解决它？

我的代码：

import rpy2.robjects as robjects
import pywin

def main():
     robjects.r("require(foreign)")
