一个小菜鸟的第一篇技术类博客，先从我今天解决的一个pycharm的报错开始吧~

这个报错我在网上找了半天，都没找到一个满意的解决方法，然后我就在想是不是django的版本不对（我之前下载的django2.0），于是我就重新下载了一个django1.11版本

于是，问题就来了：
怎样卸载以前装的django2.0呢？

我又在网上看了一圈儿，有解决方，那些解决方法里又有写什么要看当时怎么安装，是通过“pip install django == x.xx（版本号）”安装还是用什么egg啥的
反正我也不记得了

按照大神的方法我也没有找到要找的文件夹（site-packages)，于是我就用了最简单粗暴的方法：windows文件管理器的搜索功能：

然后删除所有django的文件夹就好了（好像就只有一个），对，文件夹就好

然后就可以用pip命令来安装django1.11啦~

pip install django1.11

安装完成后就可以新建项目啦，反正新我建项目之后就没有出现这个报错了~~~
(要记得新建项目哈，我刚开始没有新建项目，依然出现那个报错，大概是那个原项目里还是用的django2.0吧，不是很懂~）

处女座，虽然做了两年网络工程的学生了，但依然和小白没啥区别·····
所以只能解决这些小白问题了~~
2018年计划每周更新一篇博客
嘿嘿嘿嘿
加油啦~~
