AttributeError: module 'dis' has no attribute '_unpack_opargs'

每当我在 pycharm 中打开 python 控制台时，我都会遇到错误。我试图从位于“C:\Users\username\AppData\Local\Programs\Python\Python35\Lib\dis.py 中的 python dis.py 中找到错误，但没有找到 '_unpack_opargs' 函数。它在哪里实际上是从python文件“C:\Program Files\JetBrains\PyCharm Community Edition 2020.1\plugins\python-ce\helpers\pydev_pydevd_bundle\pydevd_bytecode_utils.py”的位置调用的。请帮忙解决这个问题。

其实我的想法是，上面的case和上面的不一样 AttributeError: module 'dis' has no attribute '_unpack_opargs' While Building Python 3.6 executable using CX_FREEZE发帖

【问题讨论】：

您的项目中有名为dis 的自定义模块/包吗？
不，我在“PyCharm Community Edition 2020.1”版本中观察到了上述问题。

标签： debugging console pycharm

【解决方案1】：

if IS_PY3K:
    long = int

try:
    _unpack_opargs = dis._unpack_opargs
except AttributeError:
    def _unpack_opargs(code):
       n = len(code)

步骤：

从if 条件中删除下面的代码行。

_unpack_opargs = dis._unpack_opargs

删除else 条件并替换为try cache 看起来像上面的代码。
