| 1 | pip install mysql |
报错：
| 1 | cryptography requires setuptools 18.5 or newer, please upgrade to a new version |
| 1 | sudo pip install --upgrade pip |
其实需要更新的是setuptools:
| 1 | sudo pip install -t /usr/local/lib/python3.6/site-packages/ setuptools |
针对多python版本的情况：
安装到python2.7:
| 1 | sudo pip install pymysql |
安装到python3.4:
| 1 | sudo pip install -t /usr/local/lib/python3.4/site-packages/ pymysql |
安装到python3.6:
| 1 | sudo pip install -t /usr/local/lib/python3.6/site-packages/ pymysql |
安装到虚拟环境中：
| 1 | sudo pip install -t ~/Pycharm/py36env/lib/python3.6/site-packages pymysql |
报错：
| 1 | Could not fetch URL https://pypi.python.org/simple/requests/: There was a problem /confirm/iing the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping |
解决方式：
| 1 | sudo pip --trusted-host pypi.python.org install -t ~/PycharmProjects/py36env/lib/python3.6/site-packages/ mysql |
问题解决。
