基于Conda完成创建多版本python环境
- 通过cmd打开conda环境
d:\ProgramData\Anaconda3\Scripts\activate
- 创建python3.7的环境
conda create -n py3.7 python=3.7
产生错误
Collecting package metadata (repodata.json): failed
UnavailableInvalidChannel: The channel is not accessible or is invalid.
channel name: pypi/simple
channel url: http://mirrors.aliyun.com/pypi/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.
