我試圖重新安裝所有庫，但沒有幫助。

任何建議，將不勝感激。

Answer 1

and where your settings.py file location？您可以編輯您manage.py和更換djangochat上有效值

if __name__ == "__main__": 
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangochat.settings") 
    #            ^^^^^^^ 

Answer 2

這個錯誤通常是因爲你有一個使用Django和Django是不導入的文件。

您的項目中可能有一個腳本導入並具有可執行功能，但不包含if __name__ == "__main__":部分。所以runserver導入這個腳本，嘗試執行並失敗，因爲django沒有被導入。所以，如果你有這樣的事情，確保運行函數在上面的if語句中，所以runserver在導入時不會嘗試運行腳本。因此，如果你想運行一個使用django的腳本（並且它不在模型，視圖，窗體中），你需要首先設置django。你需要找到有問題的文件，並添加頂部以下內容：

import django 
sys.path.append("path/to/django/settingsapp") 
os.environ["DJANGO_SETTINGS_MODULE"] = "djangochat.settings" 
django.setup()  

如果您發現有問題的文件，並添加上面，它可能會解決它。

希望這會有所幫助。

Answer 3

謝謝你所有的答案，我只是移動我的項目位置，並重新設置它，它的工作原理。仍然，我不知道是什麼問題，但移動項目目錄和環境後它正在工作。
