【参考方案1】：

你需要安装：

pip install mysqlclient

【讨论】：

当我这样做时，它会引发另一个错误 - 错误：需要 Microsoft Visual C++ 10.0。使用“Microsoft Windows SDK 7.1”获取它：www.microsoft.com/download/details.aspx?id=8279。目前我正在使用aws microsoft local server 2012。我不是用户，它有足够的空间来安装microsoft c++ 10.0。谢谢。请帮我解决这个问题。

【参考方案2】：

在进行任何迁移之前运行 pip install mysql-python。
