ModuleNotFoundError: 没有名为“_sqlite3"的模块

在 Redhat 4.4.7-18 上，我尝试使用 sqlite 运行 python3 代码，但出现以下导入错误:

On Redhat 4.4.7-18 I am trying to run python3 code using sqlite, but I get the following import error:

Traceback (most recent call last):
  File "database.py", line 7, in <module>
    import sqlite3
  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'

我尝试安装它:

>sudo pip install sqlite3
Collecting sqlite3
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProtocolError('Connection aborted.', error(101, 'Network is unreachable'))': /simple/sqlite3/

(当网络可达时...)并使用以下命令:

(while the network is reachable...) and with the following command:

> sudo yum install sqlite-devel
Loaded plugins: post-transaction-actions, product-id, refresh-packagekit,
              : rhnplugin, search-disabled-repos, security, subscription-manager
This system is receiving updates from RHN Classic or RHN Satellite.
Setting up Install Process
Package sqlite-devel-3.6.20-1.el6_7.2.x86_64 already installed and latest version
Nothing to do

所以是安装了，没有安装?有什么建议可以解决原始问题吗?

So it is installed and not installed? Any suggestion how I can solve the original problem?
