Python / Py2neo：weakref異常

Question

我通過以下方式使用Py2neo創建關系：

article = graph.merge_one("Article", "id", aid)
article2 = graph.merge_one("Article", "id", aid2)
graph.create_unique(Relationship(article, "RELATED", article2))

但是我收到以下錯誤消息：

KeyError: 'http://localhost:7474/db/data/relationship/63'
Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7f8ef4116e18>
Traceback (most recent call last):
File "/var/www/or/env/lib/python3.4/weakref.py", line 108, in remove
del self.data[wr.key]

Answer 1

你有可能遇到這個錯誤： https ： //github.com/nigelsmall/py2neo/issues/391

如果是這樣，這在2.0.6中得到修復。
