python - Flask 应用程序中导入错误

Question

我有一个申请。下面是树命令的 o/p -

app
|-- main
|   |-- lib
|   |   |-- constants.py
|   |   |-- helper.py
|   |   `-- __init__.py
|   `-- src
|       |-- __init__.py
|       `-- web.py

web.py

from flask import Flask, request  
app = Flask(__name__)

from lib.helper import endpoints
.....
Some code
.....
if __name__ == '__main__':
     app.run('0.0.0.0', 5433, debug=True)

我收到此错误

ImportError: No module named lib.helper.

我哪里做错了？

Answer 1

from flask import Flask, request  
app = Flask(__name__)

import sys
from os.path import abspath, dirname
sys.path.insert(0, dirname(dirname(abspath(__file__))))

from lib.helper import endpoints
.....
Some code
.....
if __name__ == '__main__':
    app.run('0.0.0.0', 5433, debug=True)
