【anaconda或python（pycharm)安装pandas报错】conda install pandas报错，显示下载通道不可用

一、如果是用anaconda安装pandas包出现问题

报错如下：

Collecting package metadata (current_repodata.json): failed

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