1.问题如下

ImportError while loading conftest '/Users/xxxxxxx/conftest.py'.
py._path.local.LocalPath.ImportMismatchError: ('src.conftest', '/app/src/conftest.py', local('/xxxx/conftest.py'))

2.解决方法

删除pyc，pycache文件夹即可

find . \( -name '__pycache__' -or -name '*.pyc' \) -delete

对于docker环境：
.dockerignore file, excludes pycache folders and *.pyc files from all sub/folders:

**/__pycache__
**/*.pyc
