我最近安装了 symfony，它建议我获得一个叫做 INTL 扩展的东西......

我使用 Composer 安装 symfony 之后我想添加那个扩展，所以我在我的文件夹中打开 composer.json 并像这样添加 symfony/intl

"require": {
    "symfony/intl": "2.3.*",
    "php": ">=5.3.3",
    "symfony/symfony": "2.3.*",
    "doctrine/orm": ">=2.2.3,<2.4-dev",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.3.*",
    "symfony/swiftmailer-bundle": "2.3.*",
    "symfony/monolog-bundle": "2.3.*",
    "sensio/distribution-bundle": "2.3.*",
    "sensio/framework-extra-bundle": "2.3.*",
    "sensio/generator-bundle": "2.3.*",
    "incenteev/composer-parameter-handler": "~2.0"
},

并使用了 Composer 更新，它提供了以下内容

******* path # composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
Updating the "app/config/parameters.yml" file.
Clearing the cache for the dev environment with debug true
Installing assets using the hard copy option
Installing assets for Symfony\Bundle\FrameworkBundle into web/bundles/framework
Installing assets for Acme\DemoBundle into web/bundles/acmedemo
Installing assets for Sensio\Bundle\DistributionBundle into web/bundles/sensiodi

这意味着作曲家没有下载 lib 我删除了 Composer.lock 文件并运行 Composer Install 并且 composer 仍然不需要任何东西......

但有趣的是，当我转到一个空文件夹并使用“composer require”时，它工作并下载了 INTL！我认为作曲家的目标是在我想​​要它们时添加我想要的库，那么
问题是什么？为什么我不能添加新的库？

Composer说你应该安装intl扩展（ext-intl），那么它意味着php扩展，而不是symfony/intl（因为它仅限于en）。您应该删除软件包并安装真正的扩展。在基于 debian 的系统（Ubuntu，...）上，它是包php5-intl

apt-get install php5-intl
