【Composer】国内镜像使用

1. 全局配置

composer config -g repo.packagist composer https://packagist.phpcomposer.com

2. 仅在项目中使用

#需在项目的composer.json目录执行
composer config repo.packagist composer https://packagist.phpcomposer.com

取消镜像

composer config -g --unset repos.packagist

使用国内镜像安装laravel 示例

composer create-project -vv --prefer-dist laravel/laravel myapp

如果指定国内镜像，下载会很慢，如下面的情况，一直卡住

Installing laravel/laravel (v7.0.0)
  - Installing laravel/laravel (v7.0.0): Loading from cache
 Extracting archiveCreated project in myapp
> post-root-package-install: @php -r "file_exists('.env') || copy('.env.example', '.env');"
Loading composer repositories with package information
Updating dependencies (including require-dev)

这时候可以Ctrl + c暂时终止安装，然后，为项目手动设置镜像

cd myapp
composer config repo.packagist composer https://packagist.phpcomposer.com

最后，重新安装，会快很多

composer install
php artisan key:generate
php artisan serve
