Symfony 2中的assetic:dump UglifyCss导致[Symfony\Component\Process\Exception\RuntimeException]进程已被信号“5”终止。

Question

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

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

我得到了以下结果：

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

以下是相关信息：

我的config.yml文件：

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 %}

以下是我已经尝试但没有成功的一些事情：

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

在 web/css 中的结果文件是正确的（内容包括两个 .css 文件被最小化了）。问题在于当我加载网页时，.css 文件无法正常显示。

<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) 使用以下命令递归设置文件夹权限：

chmod 777

对于文件夹：web（在我的Symfony项目内）和我的临时文件夹，它实际上是：

/var/folders/hp/vv24wsq56bs9szlt7j8bt3600000gn/T

请帮我解决这个问题，我已经没有任何想法了。

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

提前感谢您的帮助 :)

你解决了这个问题吗？ - ZloyPotroh

Answer 1

我们遇到了同样的问题，使用uglifycss过滤器处理大型css文件时会出现内存不足的情况，并且没有正确的错误信息。

您可以按照以下步骤显示确切的错误消息：

- 在您的assetic配置中禁用uglifycss过滤器 - 运行“assetic：dump”任务 - 导航到生成的css文件所在的目录，可能是web / css - 对于每个生成的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类并添加自定义Node.js参数来解决了这个问题，以获得更高的内存限制。

<?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);
    }
}

你需要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来让Assetic使用此类：

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