py2neo NameError: name 'open' is not defined

今天在使用py2neo的时候出现了下面的错误：

GraphDataUpdate.py:122: DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead
  elapsed = (time.clock() - start)

我的neo4j的数据库连接代码为：

graph = Graph(bolt=True,host=host,user=username,password=password)

解决方法

graph = Graph(secure=False, bolt=False,host=host,user=username,password=password)

把secure和bolt都置为false就行了哈。
