啟動Django項目時出現Pysqlite2錯誤

Question

我試圖從頭開始一個django項目，但是我遇到一個錯誤，提示“ ImportError：No Module Named'pysqlite2'”

我正在使用Python 3.6.0。 我將編寫以下步驟

---

Creating project 

> django-admin startproject testproject

Trying to start an app

> python manage.py startapp demo

Immediately after enters that command, it returns me a long text which includes error's path etc.

Traceback (most recent call last):

我嘗試了什么？ -我使用sudo apt get安裝了sqlite3-dev ...-我嘗試安裝pip install pysqlite2-我試圖更改位於虛擬env文件夾中的source.py，但沒有用。

但是我發現當我不使用虛擬環境時，我的意思是不輸入源代碼/ bin / activate，“ python manage.py startapp demo”命令已經起作用。 當我激活env時，它返回一個我上面提到的錯誤。

根據這個答案https://stackoverflow.com/a/23414147/2174832

沒有適用於Python 3.x的pysqlite的公共版本。 對於Python 3.x，標准庫中的sqlite3模塊是pysqlite的最新版本。

在激活的virtualenv中運行命令pip install sqlite3 ，並使用此模塊代替pysqlite2。 要激活您的virtualenv，請轉到/folderofvirtualenv/bin並運行命令source activate
