python包初始化数据库

我使用以下说明创建包:

https://python-packaging.readthedocs.io/en/latest/command-line-scripts.html

mypackage/bin
mypackage/bin/initialize_sqlite.sh
mypackage/mypackage/__init__.py
mypackage/mypackage/a_bunch_of_python.py
mypackage/mypackage/tests/__init__.py
mypackage/mypackage/tests/test_setup.py
mypackage/mypackage/maketables.sql
mypackage/setup.py

在哪里? initialize_sqlite.sh 是

#!/usr/bin/env bash

sqlite3 my.db < ../mypackage/maketables.sql # creates a Users table

setup.py是

from setuptools import setup

setup(name='mypackage,
      packages=['mypackage'],
      scripts=['bin/initialize_sqlite.sh'],
      install_requires=[
          'pysqlite3'
      ],
      test_suite='nose.collector',
      tests_require=['nose'],      
      zip_safe=False)

from pathlib import Path
import mypackage

def get_project_root():
    """Returns project root folder.
    """
    return Path(mypackage.__file__).parent.absolute()

ROOT = get_project_root()
DBFILE = str(ROOT.joinpath('my.db'))

我的mypackage/mypackage/tests/test_setup.py是:

from unittest import TestCase

import mypackage
from mypackage import utils
from pysqlite3 import dbapi2 as sqlite3 

class TestSqlAccess(TestCase):
    def test_sql_access(self):
        conn = sqlite3.connect(utils.DBFILE)
        db = conn.cursor()
        s = db.execute("PRAGMA database_list").fetchall()
        self.assertNotEqual(s, [])
        s2 = db.execute("SELECT 1 from Users LIMIT 1").fetchall()

./bin/initialize_sqlite.sh

它很好地创造了

mypackage/my.db

如我所料。

pip install ./mypackage

当我看到:

ll /home/user/anaconda3/envs/myenv/lib/python3.6/site-packages/mypackage/my.db

它是空的,大小为0。

ERROR: test_sql_access (mypackage.tests.test_setup.TestSqlAccess)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/user/.../tests/test_setup.py", line 14, in test_sql_access
    s2 = db.execute("SELECT 1 from Users LIMIT 1").fetchall()
pysqlite3.dbapi2.OperationalError: no such table: Users

我的安装箱或路径有什么问题?是不是找不到maketables.sql而没有悄悄地告诉我(所以它有效地找到了sqlite3 my.db<空文件)?
