Heroku/python无法检测到set buildpack

Question

我是一个Django新手,我创建了一个应用程序,并希望使用Heroku部署它.但是,当我这样做时git push heroku master(我跟着Heroku开始),这就是我得到的:

Counting objects: 36, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (33/33), done.
Writing objects: 100% (36/36), 19.22 KiB | 0 bytes/s, done.
Total 36 (delta 3), reused 0 (delta 0)
remote: Compressing source files... done.

我的根目录:

??? assignment

??? templates

??? db.sqlite3

??? manage.py

如果你们能提供帮助,我将非常感激.我现在真的很沮丧......

您需要添加一个requirements.txt文件,其中包含运行应用程序所需的所有模块.

您可以pip freeze > requirements.txt将所有模块冻结到一个文件中.如果你使用的是virtualenv,我只建议这样做,否则它会添加你所有的模块.

无论如何,只需确定应用程序所需的模块,并创建一个名为的文件requirements.txt并将其放入应用程序目录中.

需求文件的语法如下:

package name == version #
package name == version #
package name == version #

注意:指定某个版本号是可选的.

这是一个示例需求文件(取自本教程):

Flask==0.11
Jinja2==2.8
gunicorn==19.6.0

不要忘记提交你的requirements.txt
