Symfony 2 assetic:dump UglifyCss导致[Symfony\Component\Process\Exception\RuntimeException]进程已用信号“发出信号”；5“；

我正在开发我的第一个Symfony 2应用程序，我正在尝试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：

My 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

我的小枝模板：

{% 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 %}

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（内容包括两个.css文件）。问题是，当我加载网页时，.css被破坏：

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

*/

2） 设置文件夹权限（以递归方式）：

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

你能帮我解决这个问题吗？我已经没有主意了

注意：我将其标记为uglifyjs2，因为我没有足够的点数来创建标记uglifycss

提前感谢：）

我们遇到了同样的问题，uglifycss过滤器内存不足，大css文件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assetic配置中禁用uglifycss筛选器
• 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>test.css

• 查看哪个文件返回错误

我们通过覆盖UglifyCssFilter类并添加一个自定义Node.js参数以获得更高的内存限制来解决问题：

<?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);
    }
}

你能解决这个问题吗？

chmod 777

/var/folders/hp/vv24wsq56bs9szlt7j8bt3600000gn/T

<?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);
    }
}
