Question

有谁能告诉我出了什么问题？

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，当它尝试使用pip安装requirement.txt时，似乎没有安装Pip！

Answer 1

尝试以下方法。

1.确保已安装Ruby，然后从终端运行：

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

2.登录heroku

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

3.如果您尚未创建

，请创建您的应用

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

4.install git＆amp;项目文件夹中的git init

5.登录到heroku仪表板获取你的应用程序git存储库

6。git remote add heroku <repository url>

7.在项目中进行更改并提交

8.在项目根文件夹中创建Procfile

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

9.在项目根文件夹中创建requirements.txt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settings.py中，在文件末尾添加以下内容。

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中添加以下内容到服务器静态文件

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

12.提交您的更改并git push heroku master。现在，打开浏览器并输入https://your-app-name.heroku.com，看看魔术。

Answer 2

我自己解决了问题。解决方案是在错误消息＆＃34;需求解析错误＆＃34;之后。我发现新更新的requirements.txt文件中存在语法错误。通过纠正，问题就消失了。

遗憾的是，用户似乎无法直接看到错误的原因。希望我的共同故事可以导航将来陷入同样麻烦的编码人员。

heroku拒绝了django app push
