App Engine 모듈 가져 오기 문제

Question

App Engine에서 실행되는 Flask 기반 애플리케이션의 단위 테스트를 작성하고 있습니다.

는 documentation 당, 나는 다음과 같은 라인

import sys 

sys.path.insert(1, '/Users/vinay/tools/google_appengine') 
sys.path.insert(1, '/Users/vinay/tools/google_appengine/lib/yaml/lib') 
sys.path.insert(1, '/Users/vinay/App-Engine/zion-alpha/lib') 

여기에 전체 테스트 파일이

을 포함했다.

import sys 

sys.path.insert(1, '/Users/vinay/tools/google_appengine') 
sys.path.insert(1, '/Users/vinay/tools/google_appengine/lib/yaml/lib') 
sys.path.insert(1, '/Users/vinay/App-Engine/zion-alpha/lib') 

from pprint import pprint 
pprint(sys.path) 

from google.appengine.ext import ndb 
from webtest import TestApp 
from app import create_app 
from Tests.base_test import TestBase 

app = TestApp(create_app()) 


class AppTest(TestBase): 
    def test_index(self): 
     response = app.get('/') 
     self.assertEqual(response.content_type, 'text/plain') 
     self.assertEqual('Hello World', response.body) 

이 스크립트를 실행할 때 다음 오류가 발생합니다.

패키지는 올바른 위치에 있습니다.

bash-3.2$ ls 
google_appengine  google_appengine_1.9.40.zip 
bash-3.2$ pwd

Answer 1

당신이 생각하는 곳에 google_appengine 패키지가없는 것처럼 보입니다. 존재하지 않는 경로를 sys 경로에 추가하려고하면 오류가 표시되지 않습니다. 경로 5와 7 사이에 다음을 추가하여 경로를 확인하십시오.

from pprint import pprint 
pprint(sys.path) 

경로에 두 개 이상의 appengine pack이 있는지 확인하십시오. 각 항목을 탐색하여 실제로 있는지 확인하십시오.
