Pysqlite2錯誤，同時啓動Django項目

Question

我試着從頭開始一個Django項目，但我有，說一個錯誤「導入錯誤：沒有模塊名爲‘pysqlite2’」

我使用Python 3.6.0。我會寫步驟，這即時通訊以下

---

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.

django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3' 

我想什麼？我嘗試安裝pip install pysqlite2 - 我試圖改變虛擬env文件夾內的source.py，但它沒有工作。

但我想通了，當我不使用虛擬環境，我的意思是沒有進入源/ bin /激活，「蟒蛇manage.py startapp演示」命令已經工作。當我激活env時，它會返回上面提到的錯誤。

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

There is no public version of pysqlite for Python 3.x. For Python 3.x, the sqlite3 module in the standard library is the most up-to date version of pysqlite there is.

運行命令pip install sqlite3您激活的virtualenv內，並使用這個模塊來代替pysqlite2的。激活你的virtualenv去/folderofvirtualenv/bin 並運行命令source activate
