conda install xxx遇到Collecting package metadata (current_repodata.json): failed问题

在代码运行过程中遇到ModuleNotFoundError: No module named 'onnxruntime，然后安装onnxruntime，在命令行运行**conda install -c conda-forge onnxruntime **，报以下错误

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 429 TOO MANY REQUESTS for url <https://mirrors.ustc.edu.cn/anaconda/pkgs/main/win-64/current_repodata.json>
Elapsed: 00:46.975976

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.
'https//mirrors.ustc.edu.cn/anaconda/pkgs/main/win-64'

换镜像地址也没有得到解决，然后发现不止安装onnxruntime会报这个错误，安装别的模块如numpy也会报这个错误
后来找到一个方法成功了，步骤如下：

一、把路径“Anaconda3/Library/bin ”如下两个文件复制到“Anaconda3/DLLs”:

libcrypto-1_1-x64.dll
libssl-1_1-x64.dll

二、在命令行运行命令清除缓存

conda clean -i

三、找到C:\Users\Administrator\.condarc 这个文件，如果没有，试试自行创建，运行

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

conda config --show-sources

四、 编辑找到的.condarc文件，拷贝如下内容并覆盖原本的内容：

channels:
  - defaults
show_channel_urls: true
channel_alias: http://mirrors.tuna.tsinghua.edu.cn/anaconda
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro
  - 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

五、在运行conda update命令试试看，会看到

Collecting package metadata (current_repodata.json): done
Solving environment: |

六、重新运行命令

conda install -c conda-forge onnxruntime 

会看到

Collecting package metadata (current_repodata.json): done
Solving environment: -

安装成功
