探戈與Django：沒有模塊名爲_sqlite3

Question

我知道已經有很多人有這個問題，但我花了最後三個小時去了每一個我能找到的鏈接，我一直沒能找到解決方案爲我工作。我很尷尬不得不做這個線程，但我沒有其他選擇。

我一直在做的探戈Django的，一切都非常順利，直到我得到了這部分運行：http://www.tangowithdjango.com/book/chapters/models.html#creating-and-synchronising-the-database

在做執行syncdb命令，巨蟒不承認sqlite3的。所以我決定用一個簡單的導入測試來驗證這一點：

rob@rob-Latitude-E5400:~/code/tango_with_django_project$ python 
Python 2.7.5 (default, Sep 21 2014, 16:23:05) 
[GCC 4.6.3] on linux2 
Type "help", "copyright", "credits" or "license" for more information. 
>>> import sqlite3 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/home/rob/.pythonbrew/pythons/Python-2.7.5/lib/python2.7/sqlite3/__init__.py", line 24, in <module> 
    from dbapi2 import * 
    File "/home/rob/.pythonbrew/pythons/Python-2.7.5/lib/python2.7/sqlite3/dbapi2.py", line 27, in <module> 
    from _sqlite3 import * 
ImportError: No module named _sqlite3 
>>> 

很多人在網上也有這個相同的問題。這傢伙

提出了一些建議，以找到_sqlite3.so，並把該目錄中的PYTHONPATH。我再次運行syncdb命令，得到這個：

Traceback (most recent call last): 
    File "./manage.py", line 10, in <module> 
    execute_from_command_line(sys.argv) 
    File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 453, in execute_from_command_line

    import _io 
ImportError: /usr/lib/python2.7/lib-dynload/_io.so: undefined symbol: PyUnicodeUCS4_EncodeUTF32 

現在我卡住了。我搜索了最後一個錯誤，找不到多少。關於我的Python如何使用不同的Unicode進行編譯。這並沒有告訴我如何解決這個問題。

感謝您的閱讀和幫助。

固定。我看到這樣的響應：

然而，當我跑pip install pysqlite我收到這樣的：

[snipped] 
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -DMODULE_NAME="pysqlite2.dbapi2" -DSQLITE_OMIT_LOAD_EXTENSION=1 -I/usr/include/python2.7 -c src/module.c -o build/temp.linux-x86_64-2.7/src/module.o 

In file included from src/module.c:24:0: 

src/connection.h:26:20: fatal error: Python.h: No such file or directory 

compilation terminated. 

error: command 'gcc' failed with exit status 1 
[snipped] 

事實證明，我沒有安裝Python開發的文件。我想通了這一點，從這個帖子：http://www.linuxquestions.org/questions/linux-software-2/apparent-gcc-error-when-building-pysqlite-697318/#post3408711

所以我跑：sudo apt-get install python-dev

然後，我可以成功運行：pip install pysqlite

最後，現在當我從Django的教程中運行以下命令：./manage.py syncdb

我得到正確的輸出。我希望這可以幫助別人，因爲這個解決方案很複雜，很難在網上找到。
