composer update时报错

[ComposerDownloaderTransportException]  

 curl error 60 while downloading https://packagist.phpcomposer.com/packages.json: Peer's Certificate has expired. 

将composer.json文件中的packagist地址修改了；

"repositories": {

        "packagist": {

            "type": "composer",

            "url": "https://packagist.phpcomposer.com"

        }

    }

替换为

"repositories": {

        "packagist": {

            "type": "composer",

            "url": "https://mirrors.aliyun.com/composer/"

        }

    }
