AttributeError：模块“ readline”没有属性“ set_completer_delims”

Question

    >>> import pdb
    >>> x = [1,2,3,4,5]
    >>> y = 6
    >>> z = 7
    >>> r1 = y+z
    >>> r1
    13
    >>> r2 = x+y
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: can only concatenate list (not "int") to list
    >>> pdb.set_trace()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python3.6/pdb.py", line 1585, in set_trace
        Pdb().set_trace(sys._getframe().f_back)
      File "/usr/lib/python3.6/pdb.py", line 156, in __init__
        readline.set_completer_delims(' \t\n`@#$%^&*()=+[{]}\\|;:\'",<>?')
    AttributeError: module 'readline' has no attribute 'set_completer_delims'
    >>>

什么问题？运行python3.6发生错误 我只是尝试在Cygwin上使用pdb。 （请注意，其他lib也可以）

Answer 1

对于我来说，该问题已通过安装pyreadline得以解决：

pip install pyreadline

请尝试。
