Symfony 2資產：轉儲UglifyCss導致[Symfony \ Component \ Process \ Exception \ RuntimeException]該進程已用信號「5」發送信號

Question

我正在開發我的第一個Symfony 2應用程序，並且我正在嘗試Uglify以最小化我的.css文件。的問題是，當我執行命令：

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

我得到以下結果：

Dumping all dev assets. 
Debug mode is on.

     /Users/bender22/Proyectos/ETraining/app/../web/bundles/exam/css/exam3.css 

[Symfony的\元器件\過程\異常\的RuntimeException]
該工藝已發信號通知與信號「5」。

我的環境：

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 

這裏有一些相關的信息：

我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 

我的嫩枝模板：

{% 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 %} 

一些我已經沒有任何的運氣測試的東西：

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

$ app/console assetic:dump --verbose 

結果是

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 

在網頁結果文件/ CSS是正確的（內容包括.css文件最小化d）。問題是，當我加載網頁，名爲.css被打破：

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

，如果我點擊的href，瀏覽器顯示的內容是：

/*

2）設置文件夾訪問權限（以遞歸的方式）：

chmod 777 

的文件夾： 網站和我的temp文件夾，其結果是（我的Symfony的項目裏）：

/var/folders/hp/vv24wsq56bs9szlt7j8bt3600000gn/T 

能否請你幫我解決此問題？我已經用完了想法。

注：我已經標記這是uglifyjs2，因爲我沒有足夠的點提前:)

Answer 1

創建uglifycss

感謝標籤，我們有同樣的問題與uglifycss過濾不多了內存與大css文件沒有適當的錯誤信息。

你可以按照下面的步驟顯示確切的錯誤信息：

• 禁用uglifycss過濾器在您的assetic配置
• 運行assetic:dump任務
• 導航到CSS文件生成的目錄，大概web/css
• 運行uglifycss <filename> > test.css爲每個生成的css文件
• 看哪個文件返回錯誤

我們解決了問題，通過重寫UglifyCssFilter類，並添加自定義Node.js的參數有較高的內存限制：

<?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); 
    } 
} 

你必須改變節點的路徑到正確的位置（或改善以其他方式進行比較）。

可以讓Assetic在您的配置文件設置服務參數使用這個類：

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