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

Question

我安装了最新版本(1.0.0.稳定版)的作曲家,在我的Yii2项目中输入了这个:

php composer.phar update

它给了我这个错误:

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

[ErrorException]声明Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository :: whatProvides()应与Composer\Repository\ComposerRepository :: whatProvides(Composer\DependencyResolver\Pool $ pool,$ name,$ bypassFilters = false)兼容

有人可以帮我解决这个问题吗？

这是我的composer.json

Answer 1

大约九天前(2016年3月底左右),Composer\Repository\ComposerRepository::whatProvidesapi改变了.(#2668)因此,如果您已fxp/composer-asset-plugin全局安装,则应更新它.你可以这样做:

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

Answer 2

如果更新不起作用,请尝试此操作.

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

Answer 3

我最终通过从fxp目录中删除目录来解决问题.composer.在我的设置上,这可以解决问题:

rm -rf ~/.composer/vendor/fxp

现在当需要它时,它可以重新下载更新的插件.

Answer 4

尝试composer.json通过运行来编辑您的全局:

vi ~/.composer/composer.json 然后确保你有这一行:

{
    "require": {
        "fxp/composer-asset-plugin": "1.1.*"
    }
}

上面的答案对我不起作用,因为我的版本fxp/composer-asset-plugin就像是1.1-beta04,当我将其更改为"1.1.8"并运行更新命令时:

php /usr/bin/composer global update fxp/composer-asset-plugin --no-plugins

它解决了这个问题.但没有编辑我的全局composer.json,它给了我这个错误:

您的要求无法解析为可安装的软件包集.

问题1 - fxp/composer-asset-plugin 1.0.0-beta3的安装请求 - > fxp/composer-asset-plugin [v1.0.0-beta3]可满足. - fxp/composer-asset-plugin v1.0.0-beta3需要composer-plugin-api 1.0.0 - >找不到匹配的包.

可能的原因: - 包名称中的拼写错误 - 根据您的最小稳定性设置,包中没有足够稳定的版本,请参阅https://getcomposer.org/doc/04-schema.md#minimum-stability for更多细节.
