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：
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
conda config --add channels conda-forge执行后执行对应包的安装即可。
