无法覆盖Assetic配置中NodeJS二进制文件的路径

Question

我在重写Assetic中UglifyCSS过滤器使用的Node.js二进制文件的路径时遇到问题假设可以在/app/config/config.yml中设置路径(Symfony文档，SO问题(，但无论我将重写的值放在哪里，它似乎都没有任何效果。

为了调试它，我更改了vendor/kriswallsmith/assetic/src/Assetic/Filter/UglifyCssFilter.php中的37-39行以输出值：

/**
* @param string $uglifycssBin Absolute path to the uglifycss executable
* @param string $nodeBin      Absolute path to the folder containg node.js executable
*/
public function __construct($uglifycssBin = '/usr/bin/uglifycss', $nodeBin = null)
{
throw new RuntimeException('Path to node executable '. $nodeBin . ' Uglify executable '. $uglifycssBin . "n$PATH: ". getenv('PATH'));

这是的结果

$ ../bin/console assetic:dump --env=prod
                                                                                                          
[RuntimeException]                                                                                                                                                            
Path to node executable /usr/local/bin/node Uglify executable /home/myuser/dev/ptflow-api/app/../node_modules/.bin/uglifycss                                                
$PATH: /home/myuser/.sdkman/candidates/java/current/bin:/home/myuser/go/bin:/home/myuser/.local/bin:/home/myuser/bin/Telegram:/home/myuser/.yarn/bin:/home/carleri  
k/.config/yarn/global/node_modules/.bin:/home/myuser/bin:/home/myuser/.yarn/bin:/home/myuser/.config/yarn/global/node_modules/.bin:/home/myuser/go/bin:/home/carleri  
k/.go/bin:/home/myuser/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin                                        
                                                                                                          

这表明$nodeBin总是具有值/usr/local/bin/node。这个实际上是我系统上的正确路径，但我需要能够手动设置它，使其在找不到正确可执行文件的Docker容器中工作。

到目前为止，我看到的示例配置在是使用参数路径assetic.node还是assetic.node.bin方面有所不同，但除了assetic.filters.uglifycss.node:之外，我还设置了两者

assetic:
node: /not/a/path/config.yml/node
bin: '/usr/bin/node'

我还发现了一个文件，似乎提供了一些见解：

$ cat ./vendor/symfony/assetic-bundle/Resources/config/filters/uglifycss.xml 
<?xml version="1.0" ?>
<container xmlns="http://symfony.com/schema/dic/services"

</parameters>

<call method="setCuteComments"><argument>%assetic.filter.uglifycss.cute_comments%</argument></call>
</service>
</services>
</container>

这似乎表明设置assetic.filter.uglifycss.node或assetic.node.bin两者都应该起作用。也没有。。。XML文件似乎描述了如何使用反射来调用过滤器。我不太精通PHP开发(NodeJS、Java、.NET背景(，所以我不确定哪些代码会进一步使用它。

我使用的是Symfony 3.3和Assetic 2.8捆绑包。

OMG，我讨厌这种不直观的设置。似乎不仅构建工件被缓存，配置值也被缓存！我通过对/usr/local的整个项目进行grepping，在/var/cache中找到它的引用。

我不得不删除缓存以进行更改：

Symfony配置中的实际配置路径不是assetic.node.bin，而是assetic.node。过滤器也是如此。
