安装python模块“rpy2"安装 Enthought Canopy 后 [英] Installing python module "rpy2" after installing Enthought Canopy

问题描述

我的一些 python 脚本使用 rpy2 作为 R 的接口，它与之前的 Enthought EPD python 完美配合.

Some of my python scripts use rpy2 as an interface to R, which worked perfectly with the previous Enthought EPD python.

我最近从 Enthought 安装了 Canopy Python.Python 现在不再找到 rpy2 模块，当我尝试重新安装它时，出现以下错误:

I recently installed Canopy Python from Enthought. Python now no longer finds the rpy2 module, and when I try to reinstall it, I get the following errors:

$ easy_install rpy2

[...]

推荐答案

您的错误意味着 R 不是使用 --enable-R-shlib 构建的，或者安装程序很难找到 R.您是否也升级/重新安装/在此过程中的某处重建 R?在终端，以下命令的输出是什么:

Your error implies that R was not built with --enable-R-shlib or that the setup is having difficulty finding R. Did you also upgrade/reinstall/rebuild R somewhere in this process? At Terminal what is the output of the following commands:

echo $R_HOME

和

ls $R_HOME/lib

大概第一个显示/Library/Frameworks/R.framework/Resources 匹配 rpy 安装的位置，但是你有 libR.dylib 在第二个中可用吗?

Presumably the first shows /Library/Frameworks/R.framework/Resources which matches where the rpy install is looking, but do you have libR.dylib available in the second?

如果没有，您是否尝试过重新安装 R?

If not, have you tried reinstalling R?
