如何解決pylint中的AssertionError問題？

作爲一名python初學者，我一直試圖讓IronPython下運行的pylint運行一些腳本。我已經設法安裝並報告了一些結果，但是我每次運行它時都會收到一個AssertionError，並且在多個腳本中也是如此。如何解決pylint中的AssertionError問題？

我使用默認的rcfile運行它，除了disable=C0103,C0301,C0303之外。

輸出：

<string>:1: DeprecationWarning: object.__new__() takes no parameters

與線309 visit_default功能所指出的，如果它的使用範圍：

    assert tolineno, node

    except KeyError: 
     # FIXME: internal error ! 
     pass

這可能是pylint的問題，或者說在pylint的的支持IronPython的的。

IronPython是一個Python實現，但與其他實現方式大不相同，因爲它通常不會與Python標準庫一起使用。

您可以嘗試將此問題提交到logilab項目郵件列表，並查看他們是否有任何建議。

這似乎很明顯是一個支持IronPython的pb，更確切地說是關於AST的行號。您應該在https://bitbucket.org/logilab/pylint/issues上添加一個問題，包括IronPython版本號和導致此錯誤的最小可能的代碼段。 – sthenault
