symfony2.1.7编写器安装KnpPaginatorBundle

Question

当我运行composer.phar安装一切似乎不错：

→ sudo php composer.phar install

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update
Generating autoload files
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 FOS\JsRoutingBundle into web/bundles/fosjsrouting
etc etc

但是现在，我想安装这个包：https://github.com/KnpLabs/KnpPaginatorBundle从https://packagist.org/packages/knplabs/knp-paginator-bundle

因此，我用新的require行更新composer.json文件。

{
"require": {
    "knplabs/knp-paginator-bundle": "v2.1"
}

}

（我已经尝试了从Packegist的每个版本的分页器，仍然是相同的错误）

然后我尝试安装它：

→ sudo php composer.phar install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony/framework-standard-edition 2.1.x-dev -> satisfiable by symfony/framework-standard-edition[2.1.x-dev].
    - symfony/framework-standard-edition 2.1.x-dev requires knplabs/knp-paginator-bundle v2.1 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

以及当前composer.json的symfony2行：

    "require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.1.*",
    "doctrine/orm": ">=2.2.3,<2.4-dev",

"symfony/symfony": "2.1.x-dev" did not help

请问我该怎么做？

Answer 1

几个小时后，我终于找到了解决办法！

我不知道我的composer.json依赖性是否在某种程度上不是最好的形状，但是解决我的问题的是只更新和安装所需的包！

Woooot？？？我刚才说了什么？是的，只有需要的捆，所以...

sudo php composer.phar require 

然后通过作曲家酷搜索从https://packagist.org找到你的欲望包。

从列表中选择数字并填写版本。

它将下载捆绑包，更新composer.json和composer.lock文件：）

希望这个答案能对某人有所帮助！

应在项目目录中运行此命令：

php composer.phar update
