我如何在Ubuntu 16.04上的Python 3.7中使用带sqlite3 python模块的FTS5扩展？

Question

[要测试带有sqlite3 Python模块的FTS5扩展是否有效，我使用code中的Vorsprung durch Technik：

import sqlite3     
conn = sqlite3.connect(':memory:')
conn.execute("""create virtual table fts5test using fts5 (data);""") 
conn.execute("""insert into fts5test (data) 
                values ('this is a test of full-text search');""")
conn.execute("""select * from fts5test where data match 'full';""").fetchall() 

该代码在Ubuntu 18.04和Ubuntu 19.04上运行良好。例如，可以使用以下python3.7解释器通过Docker运行它：

docker pull ubuntu:18.04 # This line is optional.
docker run --interactive --tty ubuntu:18.04 bash
apt update
apt install -y software-properties-common
add-apt-repository -y ppa:deadsnakes/ppa
apt update 
apt install -y python3.7
python3.7
# use here the python code given above 

但是，如果我将Ubuntu版本从18.04更改为16.04，则FTS5扩展不起作用：

docker pull ubuntu:16.04 # This line is optional.
docker run --interactive --tty ubuntu:16.04 bash
apt update
apt install -y software-properties-common
add-apt-repository -y ppa:deadsnakes/ppa
apt update 
apt install -y python3.7
python3.7
# use here the python code given above 

Python代码将崩溃：

[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> conn = sqlite3.connect(':memory:')
>>> conn.execute("""create virtual table fts5test using fts5 (data);""")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
sqlite3.OperationalError: no such module: fts5

如何在Ubuntu 16.04上将带有FTS5扩展的sqlite3 Python模块和Python 3.7一起使用？

这两篇文章（Force Python to forego native sqlite3 and use the (installed) latest sqlite3 version和http://charlesleifer.com/blog/using-the-sqlite-json1-and-fts5-extensions-with-python/）可以解决此问题。
