Bower / bower-asset在php应用程序（例如yii2）中扮演什么角色 [英] what a part does bower/bower-asset play in php application such as yii2

问题描述

最近我部署了一些项目，例如 trntv / yii2-starter-kit 和依此类推。但是所有应用程序都在 @ vendor / bower而不是 @ vendor / bower / bower-asset上发布资产。我已经阅读了问题 Yii2 Composer在bower和bower-中管理软件包供应商并解决了它。但是我仍然对目录 vendor / bower / bower-asset 感到困惑。

bower / bower-asset在php应用程序中起什么作用？它不是一个作曲家程序包，而是其中的许多主题商店。此外， bower 是javascript的依赖项管理，就像 Composer for PHP一样，但是它如何解决js包的依赖关系由PHP在这种情况下我还没有安装node.js环境？

Recently I deployed some projects like trntv/yii2-starter-kit and so on.but all applications are publishing assets on '@vendor/bower' instead of'@vendor/bower/bower-asset'. I have read the question Yii2 Composer manage package in bower and bower-vendor and solved it . but I still feel confused about the directory vendor/bower/bower-asset.
What's the part does bower/bower-asset play in php application? it is not a composer package but many theme store in there. Furthermore, bower is a dependency management for javascript just like Composer for PHP , but how does it solve dependency for js package by PHP on this occasion that I have not install node.js environment?

推荐答案

Composer Asset Plugin的想法是下载Bower / NPM软件包并管理其依赖性，而无需安装Node JS，Bower和NPM（通过PHP / Composer）。

The idea of Composer Asset Plugin is to download Bower / NPM packages and manage their dependencies without having Node JS, Bower and NPM installed (through PHP / Composer). Also it adds possibility to add JavaScript dependencies for PHP packages that use JavaScript libraries.

例如，请参见 yii2-bootstrap Yii2扩展（PHP）依赖于Bootstrap（JS + CSS）：

See for example yii2-bootstrap Yii2 extension (PHP) has a dependency on Bootstrap (JS + CSS):

"bower-asset/bootstrap": "3.3.* | 3.2.* | 3.1.*"

运行 composer install 或 composer update 时，所有JS依赖项都将安装到 vendor / bower 文件夹中。

When you run composer install or composer update, all JS dependencies will be installed to vendor/bower folder.

这是内置的，但是非常模糊，受到了很多批评，并计划在 2.1.0 中将其删除（据我所知，它已包含在 2.0发行之前甚至不稳定）。不幸的是，这是必需的，并且没有禁用它的常规方法。

This is built into the core, but very ambiguous, receives a lot of criticism and there are plans to remove it in 2.1.0 (as far as I remember, it was included before release of 2.0 even it was unstable). Unfortunately this is required and there is no normal way to disable it.

您可以在扩展程序的 Github页面。

至于文件夹名称，应将其命名为 bower ，而不是 bower-asset ，如果安装正确的话。

As for folder name, it should be named bower, not bower-asset, if you installed everything correctly.

如此自动命名，请确保您具有最新版本的插件：

It's named like so automatically, make sure you have the latest version of plugin:

composer global require "fxp/composer-asset-plugin:~1.1.1"

我甚至建议改用：

composer global require "fxp/composer-asset-plugin:*"

如果有问题或错误，请执行：

If you have problems or errors, execute:

composer global remove "fxp/composer-asset-plugin"

然后重新安装，删除 vendor 和 composer.lock 您的应用程序文件夹并运行：

Then reinstall it again, delete vendor and composer.lock in your application folder and run:

composer install
