composer安装和更新很慢解决

使用国内镜像

全局配置(推荐)

所有项目都会使用该镜像地址:
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
取消配置:
composer config -g --unset repos.packagist

项目配置

仅修改当前工程配置,仅当前工程可使用该镜像地址:
composer config repo.packagist composer https://mirrors.aliyun.com/composer/
取消配置:
composer config --unset repos.packagist

调试

composer 命令增加 -vvv 可输出详细的信息,命令如下:
composer -vvv require alibabacloud/sdk

遇到问题?

1. 建议先将Composer版本升级到最新:
composer self-update

2. 执行诊断命令:
composer diagnose

3. 清除缓存:
composer clear

4. 若项目之前已通过其他源安装,则需要更新 composer.lock 文件,执行命令:
composer update --lock
