python-3.x - python3.6导入sqlite3报错

Question

我在ubuntu16.04上安装了Python3.6，安装了sqlite3。在 python2 中，我可以成功导入 sqlite，但是在 python3 中，我遇到了导入错误。谷歌试了很多方法，还是不行。我想知道如何解决它。

Python 3.6.0 (default, Mar 13 2017, 06:38:19) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

> import sqlite3

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/sqlite3/__init__.py", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/usr/local/lib/python3.6/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *

ModuleNotFoundError: No module named '_sqlite3'

Answer 1

sqlite3 将自带 python 本身。我也遇到了同样的问题，我刚刚卸载了 python3.6 并重新安装。

卸载现有的python:

sudo apt-get remove --purge python3.6

安装python3.6:

sudo apt install -y \
  build-essential \
  checkinstall

sudo apt install -y \
  libreadline-gplv2-dev \
  libncursesw5-dev \
  libssl-dev \
  libsqlite3-dev \
  tk-dev \
  libgdbm-dev \
  libc6-dev \
  libbz2-dev

PYTHON_VERSION=3.6.0

wget https://www.python.org/ftp/python/${PYTHON_VERSION}/Python-${PYTHON_VERSION}.tar.xz
tar xvf Python-${PYTHON_VERSION}.tar.xz
cd Python-${PYTHON_VERSION}/
./configure
sudo make altinstall

有效!
