报错:
Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg

这是因为pip版本太旧了,需要升级到9.0.3版本。查了网上资料,在终端执行:

curl https://bootstrap.pypa.io/get-pip.py | python

发现又报错:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/EGG-INFO/dependency_links.txt'
Consider using the `--user` option or check the permissions.

看起来是路径权限问题,又百度一下,发现改一下目录权限就可以了:

sudo chown -R 'huangpeng' /Library/Python/2.7/

这下再执行:

curl https://bootstrap.pypa.io/get-pip.py | python

就可以升级了,我的一下子升级到了pip-10.0.1 wheel-0.31.1。
后面就可以根据自己需求安装模块了,例如:

pip install pymysql

小问题,记录一下。
