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)Time used: 1.196386Exception ignored in: Traceback (most recent call last): File "/Users/admin/anaconda3/lib/python3.7/site-packages/py2neo/packages/neo4j/v1/bolt.py", line 244, in __del__ File "/Users/admin/anaconda3/lib/python3.7/site-packages/py2neo/packages/neo4j/v1/bolt.py", line 358, in close File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1383, in info File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1519, in _log File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1529, in handle File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1591, in callHandlers File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 905, in handle File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1131, in emit File "/Users/admin/anaconda3/lib/python3.7/logging/__init__.py", line 1121, in _openNameError: name 'open' is not defined

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。
