我正在尝试为我的MacOS Sierra（Python3）安装mysqlclient。
嗯，我试着按照官方页面上的指示https://github.com/PyMySQL/mysqlclient-python.
所以，一切都很好，直到：
pip install mysqlclient
pip3 install mysqlclient
它抛给我下一件事：
Collecting mysqlclient
Using cached mysqlclient-1.3.10.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/private/var/folders/q4/j199zrpj015c7dyj7qfl22qm0000gn/T/pip-build-9v6DOo/mysqlclient/setup.py", line 17, in <module>
metadata, options = get_config()
File "setup_posix.py", line 54, in get_config libraries = [dequote(i[2:]) for i in libs if i.startswith('-l')]
File "setup_posix.py", line 12, in dequote if s[0] in "\"'" and s[0] == s[-1]:

如果有人有一些想法来解决它，请帮助我。（库是通过brew下载的）。我怀疑我的苹果电脑上有Python2.7和Python3.6。但是，实际上我不知道：）
编辑：花了几个小时搜索，仍然找不到答案
https://stackoverflow.com/a/43645248/7136153这对我有帮助。我做以下事情：
brew uninstall mysql-connector-c
brew install mysql
pip3 install mysqlclient
你的pip旧了，先升级再试。
pip3 install -U pip
sudo pip3 install mysqlclient
