我正在尝试在我的mac(OS X Yosemite)上为python安装Distance。
下载软件包并解压后,我运行(如页面所述):
python setup.py install --with-c
从此我收到以下错误消息:
running build_ext

ld: library not found for -lgcc_s.10.5

根据我对this one或this previously asked question等几个帖子的理解,它看起来像clang
,通过命令gcc
调用,找不到libgcc库。
我跑了find /usr/ -name libgcc*
,这就是我得到的:

现在我被困了,因为我不知道下一步该做什么。基本上问题是:如何让clang知道库的位置?
