为什么Python无法构建？

我在Heroku上运行了一个Python/Django项目，当我推动主分支使其自动构建时，我得到了以下结果：

-----> Python app detected
-----> Installing requirements with pip
 $ python manage.py collectstatic --noinput
   /app/.heroku/python/lib/python2.7/site-packages/dotenv/main.py:24: UserWarning: Not loading /tmp/build_c2832b0dda7d9e04b969788b6541eb9e/BTCMedia-distributed-7754c155736b5d0a1512d1cd22cae8af4ff8451d/genesis/settings/.env - it doesn't exist.

   !     Error while running '$ python manage.py collectstatic --noinput'.
   See traceback above for details.
   You may need to update application code to resolve this error.
   Or, you can disable collectstatic for this application:
      $ heroku config:set DISABLE_COLLECTSTATIC=1
   https://devcenter.heroku.com/articles/django-assets
  !     Push rejected, failed to compile Python app.
  !     Push failed

我注意到，在成功的建筑中，它是这样写的

-----> Node.js app detected

那就去跑步吧

  -----> Build succeeded!
  -----> Python app detected

运行更多的东西

但是，在失败的构建中，它直接“跳过”到检测到的Python应用程序

这有什么线索吗？

知道问题可能是什么吗？

答案似乎就在您提供的输出的底部：

该页面将为您提供示例设置，您可以使用这些设置使

collectstatic

工作。

使用

heroku buildpacks

检查buildpacks（如果您有多个远程应用程序用于该回购，请使用

-a[app name]

标志）。如果您没有看到Node.js buildpack，那么您需要添加它：

heroku buildpacks:add heroku/nodejs
