ImportError：python3.3 中没有名为“_sqlite3”的模块

Question

sqlite3 错误

import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.3/sqlite3/__init__.py", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/usr/local/lib/python3.3/sqlite3/dbapi2.py", line 26, in <module>
    from _sqlite3 import *
ImportError: No module named '_sqlite3'

我使用 sqlite3 安装命令

pip install pysqlite
Downloading/unpacking pysqlite
  Downloading pysqlite-2.6.3.tar.gz (76kB): 76kB downloaded
  Running setup.py egg_info for package pysqlite

        (result, consumed) = self._buffer_decode(data, self.errors, final)

Answer 1

我想一定是你没有安装sqlite3，你可以这样做

 sudo apt-get install sqlite3  
 sqlite3 -version  
 sudo apt-get install python-pysqlite2  
 sudo apt-get install python-pysqlite2-dbg  
 sudo apt-get install libsqlite3-dev   
 sudo apt-get install sqlite  
 sudo pip install pysqlite 

然后你会找到 sqlite3

Answer 2

我在使用已编译的 3.5.7 时碰到了这个问题

wget https://www.python.org/ftp/python/3.5.7/Python-3.5.7.tgz
tar xvfz Python-3.5.7.tgz
cd Python-3.5.7
./configure --enable-optimizations
sudo make altinstall

# python3.5
>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/sqlite3/__init__.py", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/usr/local/lib/python3.5/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ImportError: No module named '_sqlite3'

解决办法：

yum install sqlite-devel
re-compile python 3.5 from source

Answer 3

对于 Ubuntu 中的 Python3：

• sudo apt-get install libsqlite3-dev
• wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz（将版本号替换为你的python3版本）
• tar -xf Python-3.6.3.tar.xz
• cd Python-3.6.3/
• ./configure --enable-loadable-sqlite-extensions && make && sudo make install

Answer 4

编译包缺东西，你应该用yum 安装这5个，然后重新编译安装python3

yum install readline-devel
yum install tk-devel
yum install tcl-devel  
yum install openssl-devel   
yum install sqlite-devel 

然后重新编译python3

tar Jxvf  Python-3.5.0.tar.xz
cd Python-3.5.0
./configure --prefix=/usr/local/python3
make && make install

Answer 5

我是 Fedora 20 用户。要解决这个问题：

1. 安装 sqlite-devel 包，使用：

   yum install sqlite-devel
   

2. 安装后，从源代码重新编译python：

   ./configure
   make && make install
   

对于多个版本的 Python，请使用 altinstall 而不是 install。
