升级了mac操作系统，安装python的python-ldap,报错
Modules/LDAPObject.c:18:10: fatal error: 'sasl.h' file not found
#include <sasl.h>
^
1 error generated.
error: command 'cc' failed with exit status 1
----------------------------------------
Cleaning up...
Command /usr/bin/python -c "import setuptools, tokenize;__file__='/private/tmp/pip_build_root/python-ldap/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-kTOYeX-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/python-ldap
Storing debug log for failure in /Users/River/Library/Logs/pip.log
找了下，原来/usr/include消失了
ll /usr/include
ls: /usr/include: No such file or directory
那么按照以下两个步骤试试
xcrun --show-sdk-path#查看sdk的路径
sudo ln -s <the_path_from_above_command>/usr/include /usr/include #建立链接
