使用composer安裝錯誤提示：

The "https://packagist.laravel-china.org/packages.json" file could not be downloaded: Peer certificate CN=*.phphub.org' did not match expected CN=packagist.laravel-china.org'
Failed to enable crypto
failed to open stream: operation failed
https://packagist.laravel-china.org could not be fully loaded, package information was loaded from the local cache and may be out of date

按說明是鏡像地址請求出錯，因而去https://packagist.laravel-china.org查看，發現Laravel China在一個月前發了篇文章《Laravel China 鏡像完成歷史使命，將於兩個月後停用》，因此很明白了，你須要換鏡像。

阿里雲 Composer 全量鏡像

Packagist 官方實時同步，推薦使用最新的 Composer 版本。

• 鏡像類型：全量鏡像
• 更新時間：1 分鐘
• 鏡像說明：阿里雲 CDN 加速，更新速度快，推薦使用

全局配置（推薦）

全部項目都會使用該鏡像地址：

 

1	composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

取消配置：

 

1	composer config -g --unset repos.packagist

項目配置

• 僅修改當前工程配置，僅當前工程可以使用該鏡像地址：composer config repo.packagist composer https://mirrors.aliyun.com/composer/
• 取消配置：composer config --unset repos.packagist

調試

• composer 命令增長 -vvv 可輸出詳細的信息，命令以下：composer -vvv require alibabacloud/sdk
