安装flask-mysql python模块时出错答案

【问题描述】：

我正在尝试安装 flask-mysql 模块并遇到错误。它看起来像是 vcvarsall.bat 的问题，但我不太确定这暗示了什么。

比我更有经验的人有什么想法吗？

C:\eb-virt\bucketlist>pip install flask-mysql

【问题讨论】：

它需要一些原生代码编译。您需要一个 Visual c++ 2008 (aka VS 9.0) 版本，它与编译 python 2.7 本身的版本相同。有一个专门用于 python 2.7 模块的微软编译器here。不过我从来没有尝试过。
还要确保你安装了正确的mysql（x86 vs x64）

【解决方案1】：

您可以尝试将这些binaries 用于windows 分发。尝试在 Windows 上安装时，Flask-mysql 使用具有 issues 的 mysql-python。见this。

【讨论】：

谢谢！您答案中的最后一个链接解决了我的问题:)

【解决方案2】：

当你安装了 python 32bit 和 mysql 64bit 时，通常会发生这种类型的错误，反之亦然。尝试相同的安装。我在这个命令 pip install psycopg2 上使用 postgresSql 和 python 遇到了这个错误也许这会解决你的问题。
