Question

我有一个sqlite3 select语句，如下所示：

con = sql.connect("testDB.db")
            cursor = con.execute("SELECT * from account")
            for row in cursor:
              print row[0]

然而，每当我执行它时，我得到一个ValueError: View function did not return a response，其追溯如下：

Traceback (most recent call last):
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1997, in __call__
    return self.wsgi_app(environ, start_response)
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1985, in wsgi_app
    response = self.handle_exception(e)
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1540, in handle_exception
    reraise(exc_type, exc_value, tb)
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1982, in wsgi_app
    response = self.full_dispatch_request()
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1615, in full_dispatch_request
    return self.finalize_request(rv)
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1630, in finalize_request
    response = self.make_response(rv)
  File "/home/alex/akiba/flask/lib/python2.7/site-packages/flask/app.py", line 1725, in make_response
    raise ValueError('View function did not return a response')
ValueError: View function did not return a response

我按照建议的here解决方案没有成功

FLASK / sqlite3选择查询返回数据类型decimal或numeric的值
