问题描述
我尝试使用命令有R 3.1.1我的电脑上安装rpy2：
I try to install rpy2 on my computer with R 3.1.1 using the command:
pip install rpy2 --user
它输出的成功，但是当我尝试使用测试它
It output success, but when I try to test it using
python -m rpy2.tests
这给我下面的错误
It give me the following error
File "/mnt/work1/software/python/2.7/lib/python2.7/runpy.py", line 162, in _run_module_as_main

这SEMES象是，在C包含R的路径没有在环境变量设置casuing的 sexp.c 不包括<$编译的情况下C $ C> Rinternals.h 从R文件夹，其中 R_ClassSymbol 定义
It semes like to be the case that the C include path of R is not set in the environment variable casuing the compilation of sexp.c does not include the Rinternals.h from the R folders, where the R_ClassSymbol is defined
然而，在〜/ .bashrc中我没设置如下：
出口C_INCLUDE_PATH =到/ mnt / WORK1 /软件/ R / 3.1.1 / lib64目录/ R /包括：$ {} C_INCLUDE_PATH
出口LD_LIBRARY_PATH =到/ mnt / WORK1 /软件/ R / 3.1.1 / lib64目录/ R / lib目录下：$ {LD_LIBRARY_PATH}
However in ~/.bashrc I did set the following: export C_INCLUDE_PATH="/mnt/work1/software/R/3.1.1/lib64/R/include:${C_INCLUDE_PATH}" export LD_LIBRARY_PATH="/mnt/work1/software/R/3.1.1/lib64/R/lib:${LD_LIBRARY_PATH}"
所以我觉得不应该发生这种错误。任何想法，为什么会发生？
So I think this error should not happen. Any Idea why it happens?

Cleaning up...
另外，请不要推荐我反正需要sudo的，如因为有时重新安装R的其他reommended。我没有在系统上的管理previlages。
Besides, Please do not recommend me anyway requires sudo such as reinstall R as sometimes reommended by others. I don't have the administrative previlages on the system.
推荐答案
附近，您将看到日志的顶部，R不是建立一个库
Near the top of the logs you will see: R was not built as a library.
研究的必须的为了rpy2工作被编译为一个共享库。
R must be compiled as a shared library in order for rpy2 to work.
