Question

作为一名python初学者，我一直在努力让在IronPython下运行的pylint运行一些脚本。我已经设法安装并报告了一些结果，但是每当我运行它时我都会收到AssertionError，并且在多个脚本上都是相同的。

我正在使用默认的rcfile保存来添加disable=C0103,C0301,C0303。

输出：

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

************* Module testscript

注意到309行的visit_default函数，如果有用的话：

@check_messages('C0321' ,'C03232', 'C0323', 'C0324')
def visit_default(self, node):
    """check the node line number and check it if not yet done"""
    if not node.is_statement:
        return
    if not node.root().pure_python:
        return # XXX block visit of child nodes
    prev_sibl = node.previous_sibling()
    if prev_sibl is not None:
        prev_line = prev_sibl.fromlineno
309>else:
        prev_line = node.parent.statement().fromlineno
    line = node.fromlineno
    assert line, node
    if prev_line == line and self._visited_lines.get(line) != 2:
        # py2.5 try: except: finally:
        if not (isinstance(node, nodes.TryExcept)
                and isinstance(node.parent, nodes.TryFinally)
                and node.fromlineno == node.parent.fromlineno):
            self.add_message('C0321', node=node)
            self._visited_lines[line] = 2
        return
    if line in self._visited_lines:
        return
    try:
        tolineno = node.blockstart_tolineno
    except AttributeError:
        tolineno = node.tolineno
    assert tolineno, node
    lines = []
    for line in xrange(line, tolineno + 1):
        self._visited_lines[line] = 1
        try:
            lines.append(self._lines[line].rstrip())
        except KeyError:
            lines.append('')
    try:
        msg_def = check_line('\n'.join(lines))
        if msg_def:
            self.add_message(msg_def[0], node=node, args=msg_def[1])
    except KeyError:
        # FIXME: internal error !
        pass

这可能是pylint中的问题，或者更确切地说是pylint对IronPython的支持。

IronPython是一个Python实现，但它与其他实现完全不同，因为它通常不与Python标准库一起使用。

您可以尝试将此问题发送到logilab项目邮件列表，看看他们是否有任何建议。

如何修复pylint中的AssertionError？
