Symfony 2 assetic：dump UglifyCss导致[Symfony \ Component \ Process \ Exception \ RuntimeException]该过程已通过信号“5”发出信号

我正在开发我的第一个Symfony 2应用程序，我正在尝试使用Uglify来最小化我的.css文件 . 问题是当我执行命令时：

$ /Applications/mampstack-5.4.17-0/php/bin/php app/console assetic:dump --verbose

我得到以下结果：

Dumping all dev assets.
Debug mode is on.

我的环境：

OS: Mac OS 10.8.4
Symfony: 2.3.2
symfony/assetic-bundle: 2.3.0
kriswallsmith/assetic: 1.1.2
Bitnami Mampstack: 5.4.17
Node.js: 0.10.13
Php: 5.4.17
Apache: 2.4.4

以下是一些相关信息：

我的config.yml：

assetic:
    debug:          %kernel.debug%
    use_controller: false
    bundles:        [ExamBundle]
    java: /usr/bin/java
    filters:
        cssrewrite: ~
        uglifyjs2:  # the path to the uglifyjs executable
            bin: /usr/local/bin/uglifyjs
            node: /usr/local/bin/node
        uglifycss:  # the path to the uglifycss executable
            bin: /usr/local/bin/uglifycss
            node: /usr/local/bin/node

我的Twig模板：

{% block stylesheets %}
    {% stylesheets output='css/generated/examlayout.css' filter='cssrewrite, uglifycss' debug=false
        'bundles/exam/css/exam.css'
        'bundles/exam/css/exam3.css'
    %}
    <link href="{{ asset_url }}" rel="stylesheet" />
    {% endstylesheets %}
{% endblock %}

我已经测试过的一些没有运气的东西：

1）执行命令（不指定/Applications/mampstack-5.4.17-0/php/bin/php）

$ app/console assetic:dump --verbose

结果是

Dumping all dev assets.
Debug mode is on.

17:55:12 [file+] /Users/bender22/Proyectos/ETraining/app/../web/css/generated/examlayout.css
    /Users/bender22/Proyectos/ETraining/app/../web/bundles/exam/css/exam.css
    /Users/bender22/Proyectos/ETraining/app/../web/bundles/exam/css/exam3.css

web / css中的结果文件是正确的（内容包括最小化的.css文件） . 问题是当我加载网页时，.css被破坏了：

<link href="/app_dev.php/css/generated/examlayout.css" rel="stylesheet" />

如果我点击href，浏览器显示的内容是：

2）使用（以递归方式）设置文件夹权限：

chmod 777

对于文件夹：web（在我的Symfony项目中）和我的临时文件夹，结果是：

/var/folders/hp/vv24wsq56bs9szlt7j8bt3600000gn/T

你能帮帮我解决这个问题吗？我已经没想完了 .

注意：我已将此标记为uglifyjs2，因为我没有足够的积分来创建标记uglifycss

    我们遇到了同样的问题，uglifycss过滤器内存不足，没有正确的错误消息 .

    您可以按照以下步骤显示确切的错误消息：

    • 在您的资产配置中禁用uglifycss过滤器

    • 运行 assetic:dump 任务

    • 导航到生成css文件的目录，可能是web / css

    • 为每个生成的css文件运行 uglifycss <filename> > test.css

    • 查看哪个文件返回错误

    我们通过重写UglifyCssFilter类并为更高的内存限制添加自定义Node.js参数来解决我们的问题：

    <?php

namespace Acme\DemoBundle\Filter;

use Assetic\Filter\UglifyCssFilter as BaseUglifyCssFilter;

class UglifyCssFilter extends BaseUglifyCssFilter
{
    protected function createProcessBuilder(array $arguments = array())
    {
        if ($arguments[0] === '/usr/bin/node') {
            $arguments = array_merge(array(
                $arguments[0],
                '--max-old-space-size=4096'
            ), array_slice($arguments, 1));
        }

        return parent::createProcessBuilder($arguments);
    }
}

    您必须将节点路径更改为正确的位置（或以其他方式改进比较） .

    您可以通过在配置文件中设置服务参数让Assetic使用此类：

    parameters:
    assetic.filter.uglifycss.class: Acme\DemoBundle\Filter\UglifyCssFilter
