2 个解决方案

#1

make sure your folder tests contains __init__.py

确保您的文件夹测试包含__init__.py

Below code appends the path of your project project to sys.path in test.py

下面的代码将项目项目的路径附加到test.py中的sys.path

python will go through to search the modules and files in your project

python将遍历搜索项目中的模块和文件

import sys
sys.path.append("/path/to/project")
from app.stamp import Timestamp

#2

Make sure project/ is in your PYTHONPATH, put and __init__.py file in the project/ directory and then you will be able to call from project.app.stamp import Timestamp.

确保项目/位于项目/目录中的PYTHONPATH,put和__init__.py文件中,然后您就可以从project.app.stamp导入时间戳调用。
