Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
- It's a private package and you forgot to add a custom repository to find it
Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
按照網上下載啥。。[composer global require "fxp/composer-asset-plugin:1.0.0"後再執行composer update即可] 無法解決，最後：
要先安裝下管理包，下面運行一個即可，如果1沒效果，就用第二個我是第二個可以了：
// 全局安裝
composer global require "fxp/composer-asset-plugin:1.2.0"
// 或者項目內引入
composer require --dev "fxp/composer-asset-plugin:^1.2.0"
加速方案：
"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.laravel-china.org"
