가상환경 생성 중 아래와 같은 에러 발생

 

conda create --name test python=3.8.0
Collecting package metadata (current_repodata.json): failed

UnavailableInvalidChannel: The channel is not accessible or is invalid.
  channel name: simple
  channel url: https://pypi.python.org/simple
  error code: 404

You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state,
and use `conda config --show-sources` to view config file locations

Repository를 https://pypi.python.org/simple로 바꾼적이 있는데 이것 때문에 에러가 발생한 듯 싶다.

해결책

conda config --remove로 채널을 삭제하라는 내용

 

conda config --remove channels https://pypi.python.org/simple로 채널 삭제, 디폴트만 남겨 두었다.
