Django执行python manage.py migrate时报如下错误：
File “/root/.python_env/.virtualenvs/venv/lib/python3.9/site-packages/django/db/backends/sqlite3/creation.py”, line 12, in is_in_memory_db
return database_name == ‘:memory:’ or ‘mode=memory’ in database_name
TypeError: argument of type ‘PosixPath’ is not iterable
这个问题应该是django2.0版本和python新版本不兼容导致的（我安装的是Django 2.2.13， Python 3.9.0）
django2.0中，django/db/backends/sqlite3/creation.py的代码如下
而最新的django3.1此处的代码为：
如果不想升级django的话可以参照新版django修改即可。
不过要在文件前面导入Path，即：
from pathlib import Path
所以改动如下：vim /root/.python_env/.virtualenvs/venv/lib/python3.9/site-packages/django/db/backends/sqlite3/creation.py
