Composer 抛出类 Fxp Composer AssetPlugin Repository NpmRepository 不存在

我安装了最新版本(1.0. 稳定版)的作曲家和在我的 Yii2项目我输入如下:

php composer.phar update

它给了我这个错误:

类 Fxp Composer AssetPlugin Repository NpmRepository 不存在

[ ErrorException ] Fxp Composer AssetPlugin Repository AbstractAssetsRepository 的声明: : whatRules ()应该与 Composer Repository ComposerRepository: : whatprovision (Composer DependencyResolver Pool $Pool，$name，$byassFilters = false)兼容

有人能帮我解决这个问题吗？

这是我的作曲家 Json

大约九天前(2016年3月底左右) ，Composer\Repository\ComposerRepository::whatProvides api 发生了变化 因此，如果你在全球范围内安装了 fxp/composer-asset-plugin，你应该更新它。你可以这样做:

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

如果更新不起作用，试试这个。

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

您可以通过在全局级别上要求它来进行永久性的修复，然后对于其他每个项目都可以解决这个问题。但是一定要把这个消息告诉你所有的团队成员。

最好是在项目范围内添加这个，这样就可以解决所有人的问题。

所以:

composer require fxp/composer-asset-plugin

小开

最后，我通过从 .composer目录中删除 fxp目录来解决这个问题。在我的设置中，这样做的诀窍:

rm -rf ~/.composer/vendor/fxp

现在，当某些东西需要它时，它可以重新下载更新后的插件。

运行以下命令编辑全局 composer.json:

然后确保上面有这条线:

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

上面的答案对我来说不起作用，因为我的 fxp/composer-asset-plugin版本就像 1.1-beta04，当我把它改成 "1.1.8"并运行 update 命令时:

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

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

无法将您的需求解决为一组可安装的包。

问题1 - fxp/writer-asset-plugin 1.0.0-beta3的安装请求-> 可由 fxp/writer-asset-plugin [ v1.0.0-beta3]满足。 - fxp/writer-asset-plugin v1.0.0-beta3需要 writer-plugin-api 1.0.0-> 没有找到匹配的包。

潜在原因: - 软件包名称中的输入错误 - 根据您的最小稳定性设置，该软件包没有足够稳定的版本 详情请参阅 https://getcomposer.org/doc/04-schema.md#minimum-stability。

在我的案例项目一二

$ composer


[ReflectionException]
Class Fxp\Composer\AssetPlugin\Repository\NpmRepository does not exist




[ErrorException]
Declaration of Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository
::whatProvides() should be compatible with Composer\Repository\ComposerRepo
sitory::whatProvides(Composer\DependencyResolver\Pool $pool, $name, $bypass
Filters = false)

Yii2，在文件夹 vendor/fxp中你需要替换文件夹 composer-asset-plugin或删除它。

小开

如果没有其他解决方案适合您，请尝试 资产包装师作为替代。

  1. 像下面这样将 包裹 鲍尔资产/引导程序和 Npm-asset/jquery添加到 comper.json:

    "require": {
"bower-asset/bootstrap": "^3.3",
"npm-asset/jquery": "^2.2"
}

  2. Add a repositories block (if you still don't have one, if you do, just append to it) with the following content:

    "repositories": [
{
"type": "composer",
"url": "https://asset-packagist.org"
}
]

  3. Run composer install (or composer update)

  4. Considering that asset-packagist installs assets in a different directory, add the following lines to your application config (usually called as web.php):

    $config = [
'aliases' => [
'@bower' => '@vendor/bower-asset',
'@npm'   => '@vendor/npm-asset',
],
];

These instructions may change over time. They have been copied from the repo website so they could last in time just in case something happens to the website. I am not the author of the repo but I really appreciate the effort made into it. Please check https://asset-packagist.org/site/about to know more about the project.

If you are struggling with composer, here you have some useful commands:

composer clear-cache - Clear composer related caches

composer install -vvv - Add the parameter "vvv" to show installation process related output (useful to debug)

composer global show - Useful to check if you already have fxp/composer-asset-plugin installed. In my case, it already was, however it was not being detected as a dependency, and the solution I described earlier worked flawless to me - hope it does work for you too!
