Django應用程序崩潰在Heroku

Question

我正在嘗試在heroku上部署我的第一個django應用程序，並一直關注Heroku網站上的指南。 我一路走到這一步，檢查Web進程是否已啟動，看起來好像應用程序正在崩潰：

(venv)Jonathans-MacBook-Air-2:myportfolio jonathanschen$ heroku ps
=== web: `python ./manage.py runserver 0.0.0.0:$PORT --noreload`
web.1: crashed for 2m

當我檢查我的日志時，有很多東西。 我已經閱讀了stackoverflow上的一些不同的帖子，我想知道我是否需要在根目錄中有一個proc文件（似乎有相互矛盾的答案）？ 這可能是導致崩潰的原因嗎？ 一如既往地感謝堆棧溢出。 這是日志：

Answer 1

有同樣的問題，當看到日志（heroku日志）時，結果發現它無法找到模塊psycopg2。

將psycopg2 == 2.4.5添加到requirements.txt文件解決了它

Answer 2

我有這個問題，問題是settings.py文件中的語法錯誤。

Answer 3

我剛剛遇到了同樣的問題並在很多問題之后弄明白了。

我注意到運行pip freeze> requirements.txt從文件中遺漏了一些必需的項目。

值得注意的是這兩個：

whitenoise == 1.0.6 wsgiref == 0.1.2

你可以在這里找到絕對需要的東西：

Heroku Django模板 - requirements.txt
