TypeError: argument of type ‘PosixPath’ is not iterable解决办法
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
