模块六没有属性 ensure_text

问题描述

出乎意料，我的 python 安装似乎坏了。尝试运行 python 脚本时，我得到以下信息...

[michael@arch ~/Code/CTF/aero/house]$ ./solve.py 
Traceback (most recent call last):
  File "/home/michael/Code/CTF/aero/house/./solve.py",line 5,in <module>
    from pwn import *
  File "/home/michael/.local/lib/python3.9/site-packages/pwn/__init__.py",line 20,in <module>
    pwnlib.update.check_automatically()
  File "/home/michael/.local/lib/python3.9/site-packages/pwnlib/update.py",line 199,in check_automatically
    log.info("\n".join(message))
  File "/home/michael/.local/lib/python3.9/site-packages/pwnlib/log.py",line 395,in info
    self._log(logging.INFO,message,args,kwargs,'info')
  File "/home/michael/.local/lib/python3.9/site-packages/pwnlib/log.py",line 292,in _log
    msg = six.ensure_text(msg)
AttributeError: module 'six' has no attribute 'ensure_text'

尝试使用 pip 重新安装模块也会中断...

[michael@arch ~/Code/CTF/aero/house]$ python3 -m pip install pwntools

ImportError: cannot import name 'ensure_text' from 'six' (/home/michael/.local/lib/python3.9/site-packages/six.py)

我已经读到这是由以 root 身份运行 pip 引起的，但我没有这样做。我最近也没有进行任何升级或安装任何新软件包。到目前为止，我已尝试设置 PYTHONPATH、重新安装 python 和重新安装 pip，但这些选项均无效。有没有人有任何想法？提前致谢！

编辑：我也尝试更新 python 和 pip，但没有用。

请求的信息：

>>> import six; print(six.__file__)
/home/michael/.local/lib/python3.9/site-packages/six.py
>>> print(six.__version__)
1.10.0

解决方法

通过在 wget https://raw.githubusercontent.com/benjaminp/six/master/six.py 中执行 ~/.local/lib/python3.9/site-packages，我能够更新六个。这解决了问题。
