Tango与Django:没有名为_sqlite3的模块

我知道已经有很多人遇到过这个问题,但是我花了最后三个小时来查看我能找到的每个链接,但我找不到适合我的解决方案。我不好意思制作这个帖子,但我别无选择。

我一直在用Tango做Django,一切都运行得很顺利,直到我到达这个部分:http://www.tangowithdjango.com/book/chapters/models.html#creating-and-synchronising-the-database

执行syncdb命令时,Python无法识别sqlite3。所以我决定用一个简单的导入测试验证这个:

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
>>> 

很多人在网上遇到同样的问题。这家伙

给出一些建议来找到_sqlite3.so,并将目录放在PYTHONPATH中。我再次运行了syncdb命令,得到了这个:

Traceback (most recent call last):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

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

现在我被卡住了。我用谷歌搜索了最后一个错误,找不到多少。关于我的Python是如何用不同的Unicode编译的。这并没有告诉我如何解决这个问题。

感谢阅读和帮助。

固定。我看到了这个回应:

然而,当我跑pip install pysqlite时,我收到了这个:

[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]

事实证明我没有安装Python开发文件。我在这篇文章中想到了这一点:http://www.linuxquestions.org/questions/linux-software-2/apparent-gcc-error-when-building-pysqlite-697318/#post3408711

所以我跑了:sudo apt-get install python-dev

然后我可以成功运行:pip install pysqlite

最后,现在我从Django教程运行命令:./manage.py syncdb

我得到了正确的输出。我希望这有助于其他人,因为这个解决方案很复杂,很难在网上找到。
