错误Orange.bio arrayexpress.query_experiments（accession ='E-MEXP-31'）

Question

我有以下橙色生物信息学代码。

#!/usr/bin/env python

from Orange.bio import arrayexpress
print arrayexpress.query_experiments(accession='E-MEXP-31')

但是当我运行它时，它会显示以下错误。

Traceback (most recent call last):
  File "./main.py", line 4, in <module>
    print arrayexpress.query_experiments(accession='E-MEXP-31')
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/orangecontrib/bio/arrayexpress.py", line 354, in query_experiments
    return parse_json(io.TextIOWrapper(stream, ecoding="utf-8"))
TypeError: 'ecoding' is an invalid keyword argument for this function

有人知道如何解决问题吗？感谢。
