An unexpected error has occurred. Conda has prepared the above report. 解决办法

When using miniconda to create a virtual environment, an error is reported:

An unexpected error has occurred. Conda has prepared the above report.

I found many methods on the Internet, all of which said:

method one

执行 conda clean --packages && conda clean --all && conda update --all

Method Two

delete this file

C:\Users[user_name].condarc

The above method may work, but if it doesn’t work after several attempts, the problem may be because you have enabled a VPN or a system proxy!
So the solution is: turn off the VPN or disable the proxy! ! ! Turn off the VPN or disable the proxy! ! ! Turn off the VPN or disable the proxy! ! ! .

If you want to open a proxy to download the python library, you can use the following method (win10 system, available for personal testing):

• Run the following code to get the proxy address and port number:

>>> from urllib.request import getproxies
>>> getproxies()
{'https': 'http://127.0.0.1:xxxxx', 'http': 'http://127.0.0.1:xxxxx'}

xxxxx is the port number.

• Add windows system variables:
  1. win+r, enter sysdm.cpl
  2. New in Advanced -> Environment Variables -> System Variables:
     
  3. Restart the computer
