Question

我遵循本教程：http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-iv-database 那家伙说我应该创建一个脚本来创建db：

#!flask/bin/python
from migrate.versioning import api
from config import SQLALCHEMY_DATABASE_URI
from config import SQLALCHEMY_MIGRATE_REPO
from app import db
import os.path
db.create_all()
if not os.path.exists(SQLALCHEMY_MIGRATE_REPO):
    api.create(SQLALCHEMY_MIGRATE_REPO, 'database repository')
    api.version_control(SQLALCHEMY_DATABASE_URI, SQLALCHEMY_MIGRATE_REPO)
else:
    api.version_control(SQLALCHEMY_DATABASE_URI, SQLALCHEMY_MIGRATE_REPO, api.version(SQLALCHEMY_MIGRATE_REPO))

但是当我尝试运行该脚本时，我得到：

/home/devuser/wapp/flask/lib/python2.7/site-packages/flask_sqlalchemy/__init__.py:800: UserWarning: SQLALCHEMY_TRACK_MODIFICATIONS adds significant overhead and will be disabled by default in the future.  Set it to True to suppress this warning.
  warnings.warn('SQLALCHEMY_TRACK_MODIFICATIONS adds significant overhead and will be disabled by default in the future.  Set it to True to suppress this warning.')

    raise e
ImportError: No module named pysqlite2

This Stackoverflow帖子不起作用。 this

当我尝试安装pysqlite时this帖子说（使用pip install pysqlite）我得到：

Collecting pysqlite
/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning
  Using cached pysqlite-2.8.1.tar.gz
    Complete output from command python setup.py egg_info:
    Only Python 2.7 is supported.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-JoH01e/pysqlite

你能帮我吗？

ImportError：没有名为pysqlite2的模块---带烧瓶的SQLAlchemy
