最近重装了系统之后，发现原有的python3环境下安装sqlite3（见原来博客：ubuntu环境下 python 3.0以上版本对sqlite3的支持问题）的办法已经行不通了。

   即使安装了libsqlite-dev之后，仍然会报这样的错误：

omnisky@omnisky:~/work/soft/Python-3.6.2$ python
Python 3.6.2 (default, Jan 21 2018, 10:08:49) 
[GCC 4.8.4] 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'针对

针对这个问题，只能采取最原始的办法来进行安装，具体操作如下;

（1）安装sqlite3的包

$ wget https://www.sqlite.org/2017/sqlite-autoconf-3170000.tar.gz --no-check-certificate
$ tar zxvf sqlite-autoconf-3170000.tar.gz
$ cd sqlite-autoconf-3170000
$ ./configure --prefix=/usr/local/sqlite3 --disable-static --enable-fts5 --enable-json1 CFLAGS="-g -O2 -DSQLITE_ENABLE_FTS3=1 -DSQLITE_ENABLE_FTS4=1 -DSQLITE_ENABLE_RTREE=1"

（2）对python3进行重新编译
$ cd Python-3.6.2
$ LD_RUN_PATH=/usr/local/sqlite3/lib ./configure LDFLAGS="-L/usr/local/sqlite3/lib" CPPFLAGS="-I /usr/local/sqlite3/include"
$ LD_RUN_PATH=/usr/local/sqlite3/lib make
$ LD_RUN_PATH=/usr/local/sqlite3/lib sudo make install

通过上述安装过程，终于可以顺利实现python对sqlite3的支持了。
