composer Deprecation Notice

今天在執行

composer global require "laravel/installer"

出現錯誤提示：

Deprecation Notice: The Composer\Package\LinkConstraint\MultiConstraint class is deprecated, use Composer\Semver\Constraint\MultiConstraintinstead.in phar:///usr/local/bin/composer/src/Composer/Package/LinkConstraint/MultiConstraint.php:17.

Deprecation Notice: The Composer\Package\LinkConstraint\LinkConstraintInterface interface is deprecated,use Composer\Semver\Constraint\ConstraintInterface instead. in phar:///usr/local/bin/composer/src/Composer/Package/LinkConstraint/LinkConstraintInterface.php:17

解決辦法：

composer global require "fxp/composer-asset-plugin:^1.2.0"
composer selfupdate

 一是作個記錄，而是給遇到一樣問題的同窗一些參考
