Therewasaproblemconfirmingthesslcertificate

使用pip install 某个包的时候报错ModuleNotFoundError: No module named ‘某个包’ &＃xff0c;错误原因是&＃xff1a;

There was a problem confirming the ssl certificate: HTTPSConnectionPool(host&＃61;&＃39;pypi.tuna.tsinghua.edu.cn&＃39;, port&＃61;443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLCertVerificationError(1, &＃39;[SSL: CERTIFICATE_VERIFY_FAILED] certificate

此时需要获得 ssl证书的认证&＃xff0c;需要在原来的安装命令后增加&＃xff1a;-i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com &＃xff08;也可换其他源&＃xff09;

例如&＃xff1a;

pip install scipy

改为&＃xff1a;

pip install scipy -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com

说明&＃xff1a;这是阿里源 --trusted-host mirrors.aliyun.com 这是为了获得ssl证书的认证
