python安装MySQL库引出的一些问题

转自：.html
1、首先用pip来安装pymysql
pip install mysql
报错：

cryptography requires setuptools 18.5 or newer, please upgrade to a new version
2、我想到的是更新pip
sudo pip install --upgrade pip
其实需要更新的是setuptools:

sudo pip install -t /usr/local/lib/python3.6/site-packages/ setuptools
3、使用pip将pymysql安装到想要的地方
针对多python版本的情况：

安装到python2.7:

sudo pip install pymysql
安装到python3.4:

sudo pip install -t /usr/local/lib/python3.4/site-packages/ pymysql
安装到python3.6:

sudo pip install -t /usr/local/lib/python3.6/site-packages/ pymysql
安装到虚拟环境中：

sudo pip install -t ~/Pycharm/py36env/lib/python3.6/site-packages pymysql
报错：

Could not fetch URL /: There was a problem confirming the ssl certificate: Can’t connect to HTTPS URL because the SSL module is not available. - skipping
解决方式：

sudo pip --trusted-host pypi.python install -t ~/PycharmProjects/py36env/lib/python3.6/site-packages/ mysql
问题解决。
