sqlite works fine with python 2.7, but when I try to import it in python 3, it will error

Removing this error I tried to reinstall sqlite3

sudo apt-get install sqlite3

but It said that the package already exists. Afterwards I tried to install it

pip3 install sqlite3

But there will be an error when installing again

But my connection is good…
What should I do now to import sqlite3 in python 3?

sqlite3 is an optional part of the standard library. It is compiled when Python 3 is compiled and installed, but only if the correct sqlite3 include file (development header File) is available.

If you have compiled and installed Python 3 yourself, install the dependencies (e.g. libsqlite3-dev or sqlite-devel or similar, depending on your Linux distribution) , Then recompile and reinstall Python 3.

Externally, the library remains as pysqlite; but that release doesn’t support Python 3. Even so, to install it, you Those sqlite development files are still needed, you need to port it to Python 3. You can also recompile Python 3.
