在尝试解决类似问题时，我在RPy2 Bitbucket上遇到了this problem thread。显然，最新的R（3.4.0＆＃34; Single Candle＆＃34;）是使用Clang 4.0.0的-fopenmp标志构建的，现在不是由Apple提供的。如果你可以使用R 3.3.3，那么这可以作为一种解决方法。或者，您可以尝试修改setup.py以通过在第272行之后添加以下内容来删除-fopenmp标记：
if "-fopenmp" in unknown:
unknown.remove("-fopenmp")
如果两者都不起作用，您可以随时强制brew使用gcc使用以下命令安装它：
env CC=/usr/local/Cellar/gcc/7.2.0/bin/gcc-7 pip install rpy2
或者如果你尝试其中一种解决方案并得到如下错误：
ld: in '/usr/local/opt/llvm/lib/libunwind.dylib', file was built for x86_64 which is not the architecture being linked (i386): /usr/local/opt/llvm/lib/libunwind.dylib for architecture i386
clang-5.0: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/local/opt/llvm/bin/clang' failed with exit status 1
您可以尝试使用以下命令进行安装：
env ARCHFLAGS="-arch x86_64" pip install rpy2
确保架构正确。或者将它们结合起来：
env ARCHFLAGS="-arch x86_64" CC=/usr/local/Cellar/gcc/7.2.0/bin/gcc-7 pip install rpy2
