ModuleNotFoundError: No module named ‘_sqlite3‘

2025-03-05 补充

Python3.10的_sqlite3.xxx.so文件，拷贝到Python3.12和Python3.13（ubuntu系统）都是不行的

可以这样解决：

sudo apt install libsqlite3-dev
cd Python-3.13.1
./configure --enable-optimizations --enable-loadable-sqlite-extensions
make
sudo make altinstall

2022-11-10 腾讯云轻量服务器ubuntu22系统，安装python3.11之后，执行sqlite3相关的单元测试时，报错如下：

ImportError while loading conftest '/home/ubuntu/github/aerich/conftest.py'.
conftest.py:8: in <module>
    from tortoise.backends.sqlite.schema_generator import SqliteSchemaGenerator
../../.cache/pypoetry/virtualenvs/aerich-gJE0JmoO-py3.11/lib/python3.11/site-packages/tortoise/backends/sqlite/__init__.py:1: in <module>
    from .client import SqliteClient
../../.cache/pypoetry/virtualenvs/aerich-gJE0JmoO-py3.11/lib/python3.11/site-packages/tortoise/backends/sqlite/client.py:3: in <module>
    import sqlite3
/usr/local/lib/python3.11/sqlite3/__init__.py:57: in <module>
    from sqlite3.dbapi2 import *
/usr/local/lib/python3.11/sqlite3/dbapi2.py:27: in <module>
    from _sqlite3 import *
E   ModuleNotFoundError: No module named '_sqlite3'

原因：python3.11是通过源码手动安装的，而系统自带的是python3.10，所以sudo apt install python3-dev命令是默认把sqlite扩展安装到python3.10下的，于是就导致3.11版本的缺少对应的.so文件

解决：把3.10的_sqlite3.xxx.so文件复制到3.11的动态库里

具体命令如下：

1. 展示python3.10的sqlite3模块的so文件路径

python3.10 -c 'import _sqlite3 as m;print(m.__file__)'

我的输出为：

/usr/lib/python3.10/lib-dynload/_sqlite3.cpython-310-x86_64-linux-gnu.so

2. 找出python3.11的动态库路径

python3.11 -c 'import random as m;print(m.__file__)'

我的输出为：

/usr/local/lib/python3.11/random.py

3. 把python3.10的so文件复制到3.11的动态库里并修改版本号(把so文件名里的310改成311)

sudo cp /usr/lib/python3.10/lib-dynload/_sqlite3.cpython-310-x86_64-linux-gnu.so /usr/local/lib/python3.11/lib-dynload/_sqlite3.cpython-311-x86_64-linux-gnu.so

复制之后，验证效果：python3.11 -c 'import _sqlite3 as m;print(m.__file__)'

2016-12-08 系统red hat6.7 也即centos6.7 python3.5.2 安装 django 之后 创建project 以及 import sqlite3

都出现  No module named ‘_sqlite3′ 

>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/Python-3.5.0/python350/lib/python3.5/sqlite3/__init__.py", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/opt/Python-3.5.0/python350/lib/python3.5/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *

解决：

1、yum -y install sqlite-devel

2、cd  Python-3.5.2       （python源码安装文件解压后的文件夹）

3、./configure --enable-loadable-sqlite-extensions --prefix=/opt/Python352     (--prefix可加可不加)

4、 make && make install

如果这几步还不行，就修改 Python-3.5.2文件夹里的setup.py文件以后，重复第三和第四步：

在 sqlite_inc_paths 中添加sqlite的include 路径
如:
        sqlite_inc_paths = [ '/usr/include',
                             '/usr/include/sqlite',
                             '/usr/include/sqlite3',
                             '/usr/local/include',
                             '/usr/local/include/sqlite',
                             '/usr/local/include/sqlite3',
                             '~/share/software/python/sqlite-3.6.20/include',     (~/share/software/python/sqlite-3.6.20是sqlite的安装路径)
                             '~/share/software/python/sqlite-3.6.20/include/sqlite3',
                           ]

二、如果是python2.7出现 import sqlite3 找不到 _sqlite模块的问题，就简单多了

1、# find / -name _sqlite*.so

/usr/lib64/python2.6/lib-dynload/_sqlite3.so

2、# whereis python2.7

python2: /usr/bin/python2.7 /usr/bin/python2 /usr/bin/python2.6 /usr/lib/python2.6 /usr/lib64/python2.6 /usr/local/bin/python2.7 /usr/local/bin/python2.7-config /usr/local/bin/python2 /usr/local/lib/python2.7 /usr/include/python2.6

3、cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/lib-dynload/_sqlite3.so

ok,搞定！
