Django - No module named _sqlite3

Question

I have django 1.4 installed on my rhel 5. By default rhel 5 has python 2.4 in it but to use django 1.4 I manually installed python 2.7.3 The development server is running fine but when I create a new project and after changing the settings.py file as :

'ENGINE': 'django.db.backends.sqlite3', 'NAME': '/home/oracle/Desktop/test1/my.db'

Now when I give python2.7 manage.py syncdb command, I get the error as:

Traceback (most recent call last):

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

Please suggest the way out?

Solution 1

At the django.db.backends.sqlite3, it tries to

try:
    try:
        from pysqlite2 import dbapi2 as Database
    except ImportError:
        from sqlite3 import dbapi2 as Database
except ImportError as exc:
    from django.core.exceptions import ImproperlyConfigured
    raise ImproperlyConfigured("Error loading either pysqlite2 or sqlite3 modules (tried in that order): %s" % exc)

So one of the modules named sqlite3 or pysqlite2 is not installed. Try to install them

$ pip install sqlite3 # or pysqlite2

Update

sqlite3 and pysqlite2 are part of Python, therefore these two packages are not in PyPi anymore.

Solution 2

You may also have compiled python by hand with no sqlite development library installed

So, do

sudo apt-get install libsqlite3-dev libsqlite3

Then, re-install python

test by entering

python
>>> import sqlite3

Solution 3

I got very similar error message when I tried to run the Django development server:

ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): dlopen(/Users/Rubinous/Projects/Jiiri2/jiiri_venv/lib/python2.7/lib-dynload/_sqlite3.so, 2): Library not loaded: /usr/local/opt/sqlite/lib/libsqlite3.0.8.6.dylib
Referenced from: /Users/Rubinous/Projects/Jiiri2/jiiri_venv/lib/python2.7/lib-dynload/_sqlite3.so
Reason: image not found

I solved this by installing pysqlite Python module with pip install pysqlite.

Solution 4

On MacOSX 10.9 (Mavericks), I had to run this command:

CPPFLAGS=-I/usr/local/opt/sqlite/include; LDFLAGS=-L/usr/local/opt/sqlite/lib; pip install pysqlite

I used homebrew to install sqlite3.

brew update; brew install sqlite

Solution 5

This is what I did to get it to work.

I am using pythonbrew(which is using pip) with python 2.7.5 installed.

I first did what Zubair(above) said and ran this command:

sudo apt-get install libsqlite3-dev

Then I ran this command:

pip install pysqlite

This fixed the database problem and I got confirmation of this when I ran:

python manager.py syncdb

in case of python 2.6 and earlier version need to install pysqlite as a separate lib.

[Dereckson]

This is now a part of Python (if compiled with this option), so there isn't any sqlite3 package anymore in pip repository: pypi.python.org/pypi/sqlite3 and pypi.python.org/pypi/pysqlite2

@Dereckson I've updated the answer regarding to your comment. Thanks

[Kimmo Hintikka]

Thanks this fixed it for me

[TauPan]

Note that pyenv install <version> will (as of today) warn about missing libzip-devel and readline, but not about missing sqlite3-devel.

@AlirezaSavand I am using django 1.10.3 with python 3.5.2 but am still facing this error. Any solution?

[Sarkhan]

@AlirezaSavand Same here

[MikeyE]

If you plan to do any debugging, you might also want to install the debug libraries using apt-get install libsqlite3-0-dbg.

Faced a missing sqlite3 for common django commands on a fresh centos7 installation. We had python2.7 altinstall to have the latest python on-bpard. Installing sqlite3 via yum and recompiling python from source saved us!
