pip install Twisted error: limits.h: No such file or directory
Environment¶
- macOS mojave - 10.14.1;
- python 2.7.15/python 3.7.1.
error message¶
The following error occurred when installing the Twisted library using pip:
In file included from /usr/local/lib/gcc/x86_64-apple-darwin15.6.0/7.1.0/include-fixed/syslimits.h:7:0,
from /usr/local/lib/gcc/x86_64-apple-darwin15.6.0/7.1.0/include-fixed/limits.h:34,
from /Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h:19,
from src/twisted/test/raiser.c:4:
/usr/local/lib/gcc/x86_64-apple-darwin15.6.0/7.1.0/include-fixed/limits.h:194:15: fatal error: limits.h: No such file or directory
#include_next <limits.h> /* recurse down to the real one */
^~~~~~~~~~
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1
solution¶
After searching the Internet for a long time, I only found a solution for linux. No one mentioned macOS.
After some research, it was found that the update of macOS mojave deliberately deleted /user/include. So I wondered whether pip can't find limit.h because /usr/include doesn't exist anymore.
So I executed the following command to manually restore the /usr/include folder again.
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
You can see that the /usr/include folder has been restored.
Execute after this
pip install Twisted
The result shows successfully installed:

Successfully built twisted
Apple's macOS 10.14 update removed /usr/include, which caused pip to find the header file and prevented the installation of the Twisted library. I hope my solution can help you all.
