原因

HTMLParseError在pythons3.5已经没有了

解决方法

将python版本回退到3.3或3.4

升级django版本

在上面一篇文章里，介绍了安装Django的方法，这里说说连接数据库吧

这篇主要介绍踩的坑和解决办法

正常连接和初始化数据库的命令是

执行这个命令的时候，出现了如下报错

经过一段排查，是我配置数据库的时候，多嵌套了一层default，修改为如下即可

然后继续执行migrate时，会报如下错误

本机环境是mac电脑，按官方教程 *** 作的时候，发现安装mysqlclient的python包会依赖本机安装mysql或者mysql-client，但在装mysql和mysql-client的时候，发现一直报错。后面发现解决办法是，在settings.py文件里，加下如下代码,即改用pymsql连接即可。

或者在settings.py同目录的__init__.py里加如上代码也可以

然后再执行python manage.py migrate命令会发现表顺利创建。新增表，不影响原有库的其他表。
