django中app模块找不到

django中app模块找不到

环境介绍

django verison=3.13, python version=3.9.0

因为要使用多个app，遂在项目目录下创建了apps这个文件夹放置其他app，在settings.py中也添加了系统路径，但问题就在这里，如下：

Pathlib方式
sys.path.append(Path(BASE_DIR).joinpath('apps'))

然后启动的时候就报错了。

Exception in thread django-main-thread:

ModuleNotFoundError: No module named 'user'
os.path方式
sys.path.append(os.path.join(BASE_DIR, 'apps'))

就很正常的启动了。

疑问?️

有没有人遇到这个问题的？Pathlib在被django解析的时候出问题了？

回答：

print看下结果啊，或者debug启动打断点看看这两者的输出差异
