Anaconda创建虚拟环境报错—UnavailableInvalidChannel: The channel is not accessible or is invalid

报错

Collecting package metadata (current_repodata.json): failed

UnavailableInvalidChannel: The channel is not accessible or is invalid.
  channel name: simple
  channel url: https://pypi.tuna.tsinghua.edu.cn/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.

解决

看错误的大致意思，应该是镜像源的问题。查了一下，果然是真的。

在cmd下输入

conda config --remove-key channels

只需恢复默认源即可，至此问题解决

PS：不过不要担心

哈哈哈，又回来了

修改镜像源

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge 
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

# 设置搜索时显示通道地址
conda config --set show_channel_urls yes

可以显示添加的来源

conda config --show channels
