Question

我尝试使用以下命令在R 3.1.1的计算机上安装rpy2：

pip install rpy2 --user

它输出成功，但是当我尝试使用

进行测试时

python -m rpy2.tests

它给我以下错误

  File "/mnt/work1/software/python/2.7/lib/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

它似乎是在环境变量中没有设置R的C包含路径的情况，因为sexp.c的编译不包括来自R文件夹的Rinternals.h，其中{ {1}}已定义

但是在R_ClassSymbol我确实设置了以下内容： export C_INCLUDE_PATH =＆＃34; /mnt/work1/software/R/3.1.1/lib64/R/include：$ {C_INCLUDE_PATH}＆＃34; export LD_LIBRARY_PATH =＆＃34; /mnt/work1/software/R/3.1.1/lib64/R/lib：$ {LD_LIBRARY_PATH}＆＃34;

所以我认为这个错误不应该发生。任何想法为什么会发生？

完整安装日志：

~/.bashrc

此外，请不要推荐我，无论如何需要sudo，如重新安装R，因为有时会被他人推荐。我没有系统的管理权限。

Answer 1

在日志顶部附近，您会看到：R未构建为库。

R 必须编译为共享库才能使rpy2正常工作。

无法正确安装rpy2
