【昊鼎王五】pip安装pymssql模块时报错“PEP 517”怎么解决？

背景

在https://blog.csdn.net/haoding205/article/details/103242102中已经讲到了如何安装pip工具，此篇就讲一个典型的安装第三方库时报错的解决方法。

报错信息

如下图：

[root@centos tmp]# pip3 install pymssql

分析

遇到问题不要怕，也不要慌，沉着冷静，总有解决方法。
仔细看报错信息，突然有一条实际上已经告诉了答案。就是版本不匹配，
，那如何才能版本匹配呢？
需要低于3.0版本的pymssql才能安装。

解决命令

命令如下：

pip install "pymssql<3.0"
pip list

如下图：

总结

当报错信息是版本不匹配时，按照提示信息，输入正确的版本限制语法，安装就成功了。

好了，聪明如你，就讲到这里吧，有问题的话可以留言。
