sqlite和pyvenv和django

Question

我是python和django的新手。我試圖讓Python 3.4和django 1.6.4在Linux Mint Mate 13的pyvenv-3.4環境中工作。我按照Using a virtual environment with Python 3.4的步驟「從源代碼構建Python 3.4」和「使用pyvenv-3.4」。然後按照Writing your first Django app的Django教程，我可以用startproject創建「mysite」。但是，命令「python manage.py runserver」失敗，因爲django.core.exceptions中有 。 ImproperlyConfigured：錯誤加載要麼pysqlite2或sqlite3的模塊 （嘗試按照這個順序）： 無模塊名爲「_sqlite3」

對不起，我不記得爲什麼我使出從源代碼編譯，但它可能是我無法使用apt-get在標準Ubuntu下載中找到pyvenv。在任何情況下，源代碼發行版的Makefile都沒有「卸載」目標，所以看起來我被安裝的任何東西卡住了，並且沒有計劃實際獲得pyvenv-python-django的工作。

我附上完整的錯誤更新這個帖子：

Answer 1

這聽起來像你沒有安裝在從源碼構建CPython的時間SQLite的開發庫。構建過程有條件地包含一些基於底層開發庫可用性的功能。

在Debian GNU/Linux及其衍生產品上安裝libsqlite3-dev。然後重新運行./configure,make和make install。
