我试图在macOS 10.14.5，python 3.7和gcc 4.7上安装python-levenshtein(https://pypi.org/progect/prog/project/python-levenshtein/(。这将失败：
/opt/local/lib/gcc47/gcc/x86_64-apple-darwin16/4.7.4/include-fixed/limits.h:169:61: fatal error: limits.h: No such file or directory
完整日志是：

有趣的是，该文件实际上 do 在我的Mac上，即：

README limits.h math.h stdint.h syslimits.h
此处问题的原因是通过Macports安装了GCC(4.7(的组合，而另一个则用Xcode运送的组合。第一个被使用。通过卸载Macports随附的较旧的GCC，可以再次使用Xcode的GCC，然后可以安装Python-Levenshtein(并编译其C代码(。
在我的计算机上(不是Mac，但结果应该翻译(，…include-fixed/limits.h包含以下
#ifdef _GCC_NEXT_LIMITS_H
#include_next <limits.h> /* recurse down to the real one */
#endif
在我的情况下，"真正的一个"似乎是/usr/include/limits.h：
$ <<< '#include <limits.h>' gcc -E -xc - |grep limits

和我的包裹经理说 /usr/include/limits.h is owned by glibc 2.29-1。
您肯定拥有Mac的Libc(不知道它叫什么(代替Glibc。也许问题是，您的系统上的LIBC比您的GCC配置的LIBC要新得多(GCC 4.7现在已经很老了(，因此它希望有一个标题可以在更新版本中移至另一个位置。
那是我的猜测。检查您的系统以找出答案。另外，如果这是一个选项，则可以尝试较新的海湾合作委员会构建。
对于我的情况，默认的 gcc在 /usr/local/bin/gcc中，它是 /usr/local/bin/gcc-4.9的软链接。
i用brew install gcc重新安装了gcc，然后将/usr/local/bin/gcc重新安装到新的gcc(我的情况下是/usr/local/bin/gcc-10(。
也针对g++进行了同样的事情，然后解决了问题。
