heroku拒絕django應用程序推

Question

任何人都可以建議我什麼是錯的？

Heroku總是拒絕代碼推送，因爲它無法構建我的代碼。從錯誤消息看來，當它試圖用pip安裝requirements.txt時，Pip未安裝！

請嘗試以下操作。

1.確保你已經安裝紅寶石，然後從你的終端運行以下命令：

wget -O- https://toolbelt.heroku.com/install-ubuntu.sh | sh 

2.Login到Heroku的

$ heroku login 
Enter your Heroku credentials. 
Email: adam@example.com 
Password (typing will be hidden): 
Authentication successful. 

3.創建您的應用程序，如果你有沒有創建

$ cd ~/myapp 
$ heroku create <app name> 

4.install git & git init在項目文件夾

5.login到Heroku的儀表盤讓你的應用程序的Git倉庫

6. git remote add heroku <repository url>

7.make項目的更改，並提交

8.create Procfile項目根文件夾

web:python manage.py runserver 
web: gunicorn <project-name>.wsgi --log-file - 
heroku ps:scale web=1 

9.創建項目根目錄中的requirements.txt文件呃

Django==1.9 
gunicorn==19.4.5 
psycopg2==2.6.1 
whitenoise==2.0.6 
wsgiref==0.1.2 
dj-database-url==0.4.1 

10.在你的settings.py添加以下在文件的末尾。

PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) 
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static') 

STATIC_URL = '/static/' 
STATICFILES_DIRS = [ 
    os.path.join(BASE_DIR, "static"), 
] 
import dj_database_url 

DATABASES['default'] = dj_database_url.config() 

11.Add在wsgi.py以下服務器的靜態文件

from whitenoise.django import DjangoWhiteNoise 
application = DjangoWhiteNoise(get_wsgi_application()) 

12.Commit更改和git push heroku master。 現在，打開你的瀏覽器並輸入https://your-app-name.heroku.com看魔術。

自己解決問題。解決方案出現錯誤消息「需求解析錯誤」。我發現新更新的require.txt文件中有一個語法錯誤。通過糾正這個問題，問題就消失了。

恥辱，似乎沒有辦法用戶可以直接看到什麼是完全錯誤的。希望我的共同故事能夠指導未來遇到同樣問題的編碼人員。
