在GoDaddy服务器上安装Python 3.5.2之后没有名为'_sqlite3'的模块

Question

我在godaddy托管服务器上安装了Python 3.5.2，当我尝试“import sqlite3”时出现以下错误。为什么呢？

Python 3.5.2 (default, Nov  7 2016, 09:01:17)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] 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 "/home/olgo/.local/lib/python3.5/sqlite3/__init__.py", line 23, in <module>
    from sqlite3.dbapi2 import *
  File "/home/olgo/.local/lib/python3.5/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ImportError: No module named '_sqlite3'

更多信息，在尝试升级软件包时：

python3 -m pip install --upgrade sqlite3
Collecting sqlite3
  Using cached sqlite3-99.0.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

        raise RuntimeError("Package 'sqlite3' must not be downloaded from pypi")
