python - 导入 rpy 给出错误

Question

我尝试使用下载安装 rpyhttp://sourceforge.net/projects/rpy/files/latest/download?source=directory

我收到此错误：

from rpy import *
Unable to determine R version from the registry. Trying another method.

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    from rpy import *
  File "C:\Python27\lib\site-packages\rpy.py", line 53, in <module>
    RHOME = rpy_tools.get_R_HOME()
  File "C:\Python27\lib\site-packages\rpy_tools.py", line 57, in get_R_HOME
    raise RuntimeError("Couldn't execute the R interpreter.\n"
RuntimeError: Couldn't execute the R interpreter.
Check whether R is in the execution path.

为什么会发生这种情况，我该如何阻止它？

Answer 1

在安装 R 期间，会显示一个复选框，让您可以选择将 R 版本号添加到注册表。

也许你没有检查它？重新安装 R 可能会有所帮助。
