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：
編輯你的composer.json文件：
"repositories": [
{
"type": "composer",
"url": "https://asset-packagist.org"
}
]
錯誤的寫法是：
"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.phpcomposer.com"
}
}
具體啥原因。。沒找到個人感覺是版本問題，因爲以前用的Linux系統可以的。換了mac就失敗。知道原因的童鞋可以寫在評論區造福代碼屆，到時候我來編輯下這篇博客。萬分感謝
