Python 3.7，MySql-Python的构建轮子失败

Question

我是python的新手，我正在尝试涉及一些MySql的django框架，并在尝试执行pip install mysqlclientcmd消息时遇到了此错误。

   Failed building wheel for mysqlclient

有谁知道如何解决这个问题？

Answer 1

我在Ubuntu上安装了以下库，之后问题就解决了。

sudo apt-get install libssl-dev

然后我可以使用以下命令安装 mysqlclient

pip install mysqlclient

Answer 2

在您的系统中为python 3.7安装 mysqlclient 之前，您需要安装以下依赖项。

sudo apt-get install python3.7-dev default-libmysqlclient-dev

我希望这能帮到您。

Answer 3

目前，官方网站上没有适用于 python 3.7 的 mysql-connector，但您可以通过安装具有特定 Windows 和 python 版本的 Wheel 来解决此问题。此解决方案pip install (ex/dir)/mysqlclient-1.3.13-cp37-cp37m-win_amd64.whl适用于 win 64-bi 和 python 3.7

检查下面的链接并下载适合您系统的特定轮子。 使用“pip install（在我的例子中带有文件名的完整路径，例如：-”pip install C:\Users\%user%\Downloads\mysqlclient-1.3.13-cp37-cp37m-win_amd64）下载并安装特定版本的轮子.whl")

Answer 4

这应该有效。

首先执行此操作

sudo apt-get install python3.7-dev

进而

pip install mysqlclient
