请问在coding如何通过composer.json安装自定义包，来部署PHP环境？

参考文档：http://docs.coding.io/languages/php

官方通过composer.json来配置PHP环境，例如：

<code>{
    "require": {"php": "5.5.16"}
}
</code>

OK，这个没有问题，我也部署成功了。现在我要使用一个第三方开发包：https://packagist.org/packages/levi/lv，修改composer.json如下：

<code>{
    "require" : {
        "php": "5.6.3",
        "levi/lv" : "dev-master",
        "ext-redis" : "*"
    }
}
</code>

就部署不成功了，错误提示如下：

<code>2015-02-08T18:20:55.67+0800 [API]     OUT Updated app with guid d645cb8f-2ec6-404f-89e7-0795b8ede261 ({"state"=>"STOPPED"})

</code>

我看官方文档有段说明是这样的：

构建

系统会运行以下命令来解决依赖：

<code>install --no-dev --prefer-dist --optimize-autoloader --no-interaction
</code>

好像是在部署的时候，默认就不执行安装开发包，那么请问如何在coding中安装一个第三方开发包呢？

找到答案
http://ryankent.ca/getting-started-with-laravel-and-php-on-heroku/
http://mattstauffer.co/blog/installing-a-laravel-app-on-heroku

原话如下：

We might also run into some problems with composer because Laravel doesn't add composer.lock to git by default. If you get the following error when pushing to Heroku you need to make sure you remove composer.lock from your .gitignore so it can be pushed correctly.

<code>!     ERROR:        Your composer.json specifies dependencies, but no composer.lock
     was found, please check it into your repository along with composer.json!

!     Push rejected, failed to compile PHP app
</code>

意思是确保项目中没有composer.lock。

修改.gitignore，将composer.lock传上来就好了
