Python Flask导入错误：没有名为xx的模块

Question

我在mac上的Python3.7上运行代码。你知道吗

因为某种原因，当我试着运行运行.py“文件它打印出这个错误：

Traceback (most recent call last):
File "/Users/sxxx/Desktop/python-project/aimupapp/routes.py", line 2, in <module>
from aimupapp import app
ModuleNotFoundError: No module named 'aimupapp'
[Finished in 0.7s with exit code 1]
[shell_cmd: python -u "/Users/sxxx/Desktop/python-project/aimupapp/routes.py"]
[dir: /Users/sxxx/Desktop/python-project/aimupapp]
[path: /Library/Frameworks/Python.framework/Versions/3.7/bin:/anaconda3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin]

这是我的文件夹结构：

│   ├── __init__.py
│   ├── __pycache__
│   ├── forms.py
│   ├── models.py
│   ├── routes.py
│   ├── site.db

│       ├── tutor.html
│       ├── ..
└── run.py

from aimupapp import app
if __name__ == '__main__':
app.run(debug=True)

__init__.py

app = Flask(__name__)
app.config['SECRET_KEY'] = 'xxxx'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///site.db'
db = SQLAlchemy(app)
bcrypt = Bcrypt(app)
