Python/Django運行開發服務器

Question

我想創建一個項目使用Django 1.8.4和Python 2.7.10，但我不能執行命令python manage.py runserver。我可以創建項目和應用程序，但無法運行服務器。 請有人幫助我，我是新的Python/Django，我無法進一步提高。 命令執行時，cmd顯示下一個錯誤。

Answer 1

它似乎很清楚，Django是無法在指定位置找到您的數據庫，原因可以，

1. 您已經使用「命令」或比你當前用戶的任何其他其他Linux用戶，這就是爲什麼你的當前用戶可能沒有權限訪問該數據庫中創建的Django項目。你可以在你的項目的根目錄下鍵入檢查文件的權限，

   LS -la

2. 你已經在你的settings.py配置數據庫文件的路徑不對

Answer 2

我相信你正在尋找的解決方案是：

sudo python manage.py runserver 

我用同樣的問題掙扎，這終於做的伎倆我。
