资产-无法写入资产

Question

下面是我的目录结构(这只是一个测试项目)：

stan@mypc:/generate_assets$ sudo tree -L 3 -p
.
├── [drwxr-xr-x]  assets
│   └── [drwxr-xr-x]  css
│       ├── [-rw-r--r--]  test1.css
│       └── [-rw-r--r--]  test2.css
├── [-rw-r--r--]  composer.json
├── [-rw-r--r--]  composer.lock
├── [drwxrwxrwx]  public
├── [-rwxr-xr-x]  run
└── [drwxr-xr-x]  vendor
     ....skipping...

下面是我应该生成资产的简单脚本(“run”文件)：

#!/usr/bin/env php

<?php
    //loading composer's autoload
    chdir(__DIR__);
    if (file_exists('vendor/autoload.php')) {
        include 'vendor/autoload.php';
    }

    use Assetic\Asset\AssetCollection;
    use Assetic\Factory\AssetFactory;
    use Assetic\Asset\FileAsset;
    use Assetic\Asset\GlobAsset;
    use Assetic\Filter\LessFilter;
    use Assetic\Filter\CssMinFilter;
    use Assetic\AssetWriter;
    use Assetic\AssetManager;

    //Asset manager
    $am = new AssetManager();

    //Add all css files
    $css = new GlobAsset('assets/css/*.css', array(new CssMinFilter()));
    $am->set('basecss', $css);

    // Dumping assets into public
    $writer = new AssetWriter('public');
    $writer->writeManagerAssets($am);

因此，我预计资产/ css中的css文件将合并、缩小并转储到公共目录中，名为“basecss.css”。我得到的例外是：

PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'Unable to write file public/' in /generate_assets/vendor/kriswallsmith/assetic/src/Assetic/AssetWriter.php:106
Stack trace:
#0 /generate_assets/vendor/kriswallsmith/assetic/src/Assetic/AssetWriter.php(65): Assetic\AssetWriter::write('public/', '*{color:green}?...')
#1 /generate_assets/vendor/kriswallsmith/assetic/src/Assetic/AssetWriter.php(54): Assetic\AssetWriter->writeAsset(Object(Assetic\Asset\GlobAsset))
#2 /generate_assets/run(31): Assetic\AssetWriter->writeManagerAssets(Object(Assetic\AssetManager))
#3 {main}
  thrown in /generate_assets/vendor/kriswallsmith/assetic/src/Assetic/AssetWriter.php on line 106

所以-似乎assetic试图转储名为“public”的文件，而不是“public/basecss.css”？有什么帮助吗？

P.S.决议：

好的。苏。显然我得走了

$css->setTargetPath('css_file_name.css');   

然后成功了..。

文档中并不完全清楚，但在将资产转储到静态文件部分中确实提到

$writer->writeManagerAssets($am);

“将利用资产的目标路径。”因此，是的，正如您建议的那样，在编写资产之前设置目标路径将解决问题：

$css->setTargetPath('css_file_name.css');
