heroku拒绝django应用程序推

Question

任何人都可以建议我什么是错的？

Heroku总是拒绝代码推送，因为它无法构建我的代码。从错误消息看来，当它试图用pip安装requirements.txt时，Pip未安装！

请尝试以下操作。

1.确保你已经安装红宝石，然后从你的终端运行以下命令：

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.创建您的应用程序，如果你有没有创建

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

4.install git & git init在项目文件夹

5.login到Heroku的仪表盘让你的应用程序的Git仓库

6. git remote add heroku <repository url>

7.make项目的更改，并提交

8.create Procfile项目根文件夹

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

9.创建项目根目录中的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以下服务器的静态文件

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

12.Commit更改和git push heroku master。 现在，打开你的浏览器并输入https://your-app-name.heroku.com看魔术。

自己解决问题。解决方案出现错误消息“需求解析错误”。我发现新更新的require.txt文件中有一个语法错误。通过纠正这个问题，问题就消失了。

耻辱，似乎没有办法用户可以直接看到什么是完全错误的。希望我的共同故事能够指导未来遇到同样问题的编码人员。
