使用Heroku在Flask中导入模块错误和NameError

Question

I do have this issue when deploying a small app to heroku, the requirements.txt is very minimal, the app crash with Cannot import module 'NewsApiClient' when using

from newsapi import NewsApiClient

and the app actually start with a 500 Internal Error when using from newsapi import *

NameError: name 'NewsApiClient' is not defined

newsapi = NewsApiClient(api_key='xxxxxxxxxx')

What I've done so far is create an empty init file on the root folder

Answer 1

It appears you are importing the incorrect package in your requirements.txt file. You have imported the newsapi package which is different then the python-newsapi package.

Changing the newsapi==0.1.1 to newsapi-python==0.2.3 should fix your problem with the importing error as long as you reinstall the package dependencies.
