Question

我试图在macOS 10.14.5，Python 3.7和gcc 4.7上点安装python-Levenshtein（https://pypi.org/project/python-Levenshtein/）。此操作失败：

/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

有趣的是，我的Mac上确实存在文件，即：

felix@fxa-2:~$ ls /opt/local/lib/gcc47/gcc/x86_64-apple-darwin16/4.7.4/include-fixed
README       limits.h     math.h       stdint.h     syslimits.h

Answer 1

在我的计算机上（不是Mac，但应转换结果），…include-fixed/limits.h包含以下内容

#ifdef _GCC_NEXT_LIMITS_H
#include_next <limits.h>                /* recurse down to the real one */
#endif

在我的情况下，“真实的”似乎是/usr/include/limits.h：

$ <<< '#include <limits.h>'  gcc -E -xc - |grep limits
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 1 3 4
# 34 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 3 4
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/syslimits.h" 1 3 4
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 1 3 4
# 194 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 3 4
# 1 "/usr/include/limits.h" 1 3 4
# 26 "/usr/include/limits.h" 3 4
# 27 "/usr/include/limits.h" 2 3 4
# 183 "/usr/include/limits.h" 3 4
# 1 "/usr/include/linux/limits.h" 1 3 4
# 184 "/usr/include/limits.h" 2 3 4
# 188 "/usr/include/limits.h" 2 3 4
# 195 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 2 3 4
# 8 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/syslimits.h" 2 3 4
# 35 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 2 3 4

我的包裹经理说 /usr/include/limits.h is owned by glibc 2.29-1。

您肯定有Mac的libc（不知道它叫什么）来代替Glibc。也许问题是系统上的libc比您的gcc所配置的libc要新得多（gcc 4.7现在已经很旧了），因此它期望头文件已被移动到较新版本中的另一个位置。

那是我的猜测。检查您的系统以找出答案。另外，如果可以的话，您可以尝试更新的gcc构建。

Answer 2

此问题的原因是通过macports安装的gcc（4.7）和xcode附带的另一个gcc的组合。使用第一个。通过卸载macports随附的较旧的gcc，可以再次使用xcode的gcc，进而可以安装python-Levenshtein（并编译其C代码）。

Answer 3

就我而言，默认 gcc 位于 /usr/local/bin/gcc 中，它是指向 /usr/local/bin/gcc-4.9 的软链接。

我用 gcc 重新安装了 brew install gcc，并将 /usr/local/bin/gcc 重新链接到新的 gcc，在我的情况下是 /usr/local/bin/gcc-10。

对g++也做了同样的事情，然后问题就解决了。

gcc：致命错误：limits.h：macos上没有这样的文件或目录
