python - Pylint 导致 RuntimeError：生成器使用最新的包版本引发了 StopIteration

Question

这是我的软件包版本，

$ pylint --version
pylint 2.3.1
astroid 2.2.5
Python 3.7.4 (default, Aug 14 2019, 12:09:51) 
[GCC 8.3.0]

当我跑

pylint {package_name}

我得到RuntimeError如下所示：

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/astroid/protocols.py", line 492, in _infer_context_manager
    enter = next(inferred.igetattr("__enter__", context=context))
StopIteration

The above exception was the direct cause of the following exception:

RuntimeError: generator raised StopIteration

从一些搜索来看，这个错误似乎应该已经Pylint 2.x用Python 3.7. 有什么修复吗？
