Question

我正在用Ironpython编程，想使用Paho。

我做了以下事情：

C:\Program Files\IronPython 2.7\Scripts>pip install paho-mqtt
Collecting paho-mqtt

  Complete output from command python setup.py egg_info:
  Traceback (most recent call last):
   File "<string>", line 1, in <module>
   File "c:\program files\ironpython 2.7\Lib\site-packages\setuptools\__init__.py", line 151, in <module>
  TypeError: a new-style class can't have only classic bases

  ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\appdata\local\temp\pip-install-8fzpf3\paho-mqtt\
You are using pip version 18.1, however version 20.2b1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

对此错误进行了Google搜索，并导致以下错误（（{Python: setup.py egg_info failed with error code 1）：

确保它是最新的

pip install --upgrade setuptools 确保模块ez_setup不丢失

pip install ez_setup 然后试试这个

pip安装展开如果仍然无法正常工作，请尝试

easy_install -U setuptools 然后

pip安装展开

但是，pip install ez_setup命令返回相同的错误：

C:\Program Files\IronPython 2.7\Scripts>pip install ez_setup
Collecting ez_setup
