Python 3.7，为MySql构建轮子失败-Python

Question

我是python的新手，我正在尝试涉及一些MySql的django框架，在尝试做pip install mysqlclient和cmd消息时遇到了这个错误，我得到了这个。

有人知道怎么解决这个问题吗？

Answer 1

我在Ubuntu上安装了下面的库，之后这个问题就解决了。

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

在系统中安装mysqlclient for python 3.7之前，您需要安装以下依赖项。

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

我希望这能对你有所帮助。

Answer 3

目前，mysql-connector for python3.7在官方的wesite中不可用，但是你可以通过安装带有特定窗口和python版本的轮子来修复这个问题。此解决方案适用于win 64-bi和Python3.7的pip install (ex/dir)/mysqlclient-1.3.13-cp37-cp37m-win_amd64.whl

检查下面的链接并下载适用于您的系统的特定轮子。download and install the wheel for specific version by using "pip install (full path with file name in my case ex:-"pip install C:\Users\%user%\Downloads\mysqlclient-1.3.13-cp37-cp37m-win_amd64.whl")
