運行 Django 時出錯：ModuleNotFoundError：沒有名為“pyshop.settings”的模塊

Question

我已經開始學習 Django 並且無法運行服務器。

Python and PyCharm are freshly installed I have installed Django by command pip install Django . 之后，當我運行命令python manage.py runserver它給我錯誤：

沒有這樣的文件和目錄

所以我復制了manage.py文件並粘貼在寫入的路徑下，當我再次輸入時，它向我顯示了這個奇怪的長錯誤我已經嘗試了每條路徑，但它給了我一個錯誤，即只有一個路徑上沒有這樣的文件和目錄這給了我一個奇怪的長錯誤

(venv) C:\Users\Usman Raees\PycharmProjects\pyshop>python manage.py runserver

Answer 1

因為你剛開始學習。 在 python（pycharm 專業版）中創建一個新的 Django 項目並再次啟動應用程序，不要將 manage.py 文件復制到任何地方。 還運行

$ django-admin.py startproject Yourprojectname

在你運行之前

python manage.py runserver

Answer 2

python manage.py 依賴於 settings.py 文件中的配置。 檢查您是否仍然有 settings.py，您可能已將其刪除是我的錯誤。 那對我有用
