请问如何在win8下面如何用命令行安装mysql-connector-python
我用课程里讲的下载安装的方法安装成功了，但是我要在python的虚拟环境中操作数据库，但是虚拟环境中无法使用环境外部的Python插件，所以要使用命令行在venv下安装，请问老师该如何安装呢？
我用了一下两种都没有成功：
第一种：我查的网上有说有python setup.py install安装，但是我把下载的MySQL-python-1.2.3.win32-py2.7.exe解压发现里面没有setup.py文件。请老师给我指点一下安装的方法谢谢。
第二种：
> pip install mysql-connector-python

You should consider upgrading via the 'python -m pip install --upgrade pip' command.
