报错内容一：

Solving environment: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/conda-forge/noarch/repodata.json\>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
SSLError(MaxRetryError('HTTPSConnectionPool(host=\'conda.anaconda.org\', port=443): Max retries exceeded with url: /conda-forge/noarch/repodata.json (Caused by SSLError(SSLError("bad handshake: Error([(\'SSL routines\', \'ssl3_get_server_certificate\', \'certificate verify failed\')])")))'))

解决方法：

切记看好自己的系统是windows还是linux。网上很多方法均是添加镜像源，但是windows和linux是不相同的，不可以直接按照网上增加镜像源。

1）vim ~/.condarc

2）通过i 进入vim编辑模式，添加如下内容：

复制代码

channels:
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

3）通过 ESC + :wq保存退出

4）重新创建环境 conda create -n xxx python=3.9

报错内容二：

To search for alternate channels that may provide the conda package you're
looking for, navigate to
https://anaconda.org
and use the search bar at the top of the page.

解决方法：只需要在下包之前输入如下命令就可以了

复制代码

 conda config --add channels conda-forge

执行后执行对应包的安装即可。
