heroku拒絕了Django應用程序推送

Question

誰能建議我出了什么問題？

Heroku總是拒絕代碼推送，因為它無法構建我的代碼。 從錯誤消息看來，當嘗試使用pip安裝require.txt時，似乎未安裝Pip！

嘗試以下方法。

1.確保已安裝Ruby，然后從終端運行此程序：

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

2.登錄到Heroku

$ 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（如果尚未創建）

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

4.在您的項目文件夾中安裝git ＆ git init

5.登錄到Heroku儀表板獲取您的應用程序git存儲庫

6. git remote add heroku <repository url>

7，在項目中進行更改並提交

Procfile在項目根文件夾中創建Procfile

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

9.Create requirements.txt在項目的根文件夾中的文件

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.在您的settings.py文件的末尾添加以下內容。

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.在wsgi.py中將以下內容wsgi.py到服務器靜態文件中

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

12.提交您的更改並git push heroku master 。 現在，打開瀏覽器，然后輸入https://your-app-name.heroku.com了解魔術。

問題由我自己解決。 解決方案遵循錯誤消息“ requirement parse error”。 我發現新更新的require.txt文件中存在語法錯誤。 通過糾正這一點，問題就消失了。

令人遺憾的是，用戶似乎無法直接看到到底出了什么問題。 希望我分享的故事能幫助將來遇到同樣麻煩的編碼人員。
