rpy2找不到inlcude目录

在安装rpy2软件包时使用以下命令：python setup.py build install，安装过程会引发以下错误。rpy2找不到inlcude目录

我配置了两个环境变量，指向缺少的文件。

export R_HOME=/data/myprojects/R/R-devel 
export R_INCLUDE_DIR=/data/myprojects/R/R-devel/include

问题：如何修复setup.py进程的配置以查找包含头文件。

输出的关键提示是：

R was not built as a library

[R必须按顺序作为共享库rpy2能够使用共享库（见这里的音符：http://rpy2.readthedocs.io/en/version_2.7.x/overview.html#using-rpy2-with-other-versions-of-r-or-python）。

我做了这样的工作：

cd rpy2-2.8.2 
ln -s /usr/local/lib/R/include/* rpy/rinterface/

替代，当然你rpy2版本。您可以使用“R RHOME”命令找到包含的位置。所以更一般的是：

ln -s RHOME/include/* rpy2-X.X.X/rpy/rinterface/

在哪里填写RHOME路径和rpy2版本号。
