Collecting package metadata (current_repodata.json): failed

CondaSSLError: OpenSSL appears to be unavailable on this machine. OpenSSL is required to

Exception: HTTPSConnectionPool(host='mirrors.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /anaconda/cloud/Paddle/win-64/current_repodata.json (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available."))

问题解决

找到 Anaconda 的安装目录>Library>bin，如C:\ProgramData\Anaconda3\Library\bin，复制该文件夹下的两个文件

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

然后将这两个文件粘贴到 Anaconda 的安装目录>DLLs，如C:\ProgramData\Anaconda3\DLLs。
然后重新执行 conda install 命令即可。
