更新composer抛出异常类Fxp\Composer\AssetPlugin\Repository\NpmRepository不存在

Question

我最近为Yii2基本应用程序模板运行了最新的作曲家安装.

但是运行php composer.phar install抛出了这个异常:

类Fxp\Composer\AssetPlugin\Repository\NpmRepository不存在

"yiisoft/yii2-composer"插件需要composer-plugin-api 1.0.0,这个WIL L在未来中断,应该尽快修复(例如需要^ 1.0).

[ReflectionException]类Fxp\Composer\AssetPlugin\Repository\NpmRepository不存在

[ErrorException]

声明Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository :: w hatProvides()应该与Composer\Repository\ComposerRepository :: whatProvides(Composer\DependencyResolver\Pool $ pool,$ name,$ bypassFilters = fal se)兼容

这是我的composer.json:

        }
    }
}

什么可能出错？有没有人遇到过这个？

像错误消息说:

The "yiisoft/yii2-composer" plugin requires composer-plugin-api 1.0.0, this WILL break in the future and it should be fixed ASAP (require ^1.0 for example).

尝试更新您的fxp/composer-asset-plugin:

php composer.phar global update fxp/composer-asset-plugin --no-plugins

PS:如果更新后仍无法正常工作,请尝试以下操作:

composer global require fxp/composer-asset-plugin --no-plugins
