我正在尝试使用Heroku CLI将我的Django项目部署到Heroku上。我创建了一个应用程序，然后从项目目录中运行git push heroku master命令。但是，我收到了以下错误信息：
remote: -----> $ python manage.py collectstatic --noinput
remote: Traceback (most recent call last):
remote: File "manage.py", line 15, in <module>
remote: execute_from_command_line(sys.argv)

remote: from decouple import Csv, config
remote: ImportError: No module named 'decouple'
remote:
remote: ! Error while running '$ python manage.py collectstatic --noinput'.
remote: See traceback above for details.
remote:
remote: You may need to update application code to resolve this error.
remote: Or, you can disable collectstatic for this application: remote:
remote: $ heroku config:set DISABLE_COLLECTSTATIC=1
remote:
remote: https://devcenter.heroku.com/articles/django-assets
remote: ! Push rejected, failed to compile Python app.
remote:
remote: ! Push failed
所以，如前所述，我运行了
heroku config:set DISABLE_COLLECTSTATIC=1。然后将代码推送到存储库中。然后我运行了heroku run python3 manage.py migrate。但是仍然出现相同的错误，提示：
文件“/app/funderpreneur/settings.py”的第15行
from decouple import Csv, config ImportError: No module named 'decouple'
但是我已经在本地安装了python-decouple，用于python 2和3。整个项目正在运行django版本2和python版本3.5.2。但是在runtime.txt中，我设置了python-3.6.4。我的requirements.txt中已经有了decouple。
在我的settings.py文件中，我有：
import django_heroku
django_heroku.settings(locals())
但我一直在遇到错误，所以我将它们注释掉了，但仍然出现错误。
是哪里出了问题或者我做错了什么？
编辑
我的requirements.txt文件:
dj-database-url

gunicorn
psycopg2
whitenoise
dj-static
Unipath
python-decouple
Pillow
