我正在使用Laravel 4 Framework制作的项目，然后我用这个命令安装了作曲家。
composer install
这是执行结果：

在OSX（Mountain Lion）和Windows 7 Home Premium上显示相同的错误消息。我现在该怎么办？
请帮帮我！提前谢谢。
答案 0 :(得分：1)
似乎是一个代码套装问题，而不是laravel / composer。
您之前是否安装过codesleeve？
尝试从app / config / app.php文件中删除该行
从composer.json删除codesleeve
运行作曲家更新。现在一切都应该正常工作。
将codesleeve重新添加到composer.json
运行另一个作曲家更新
将codeleeve服务提供商重新添加到app / config / app.php
运行composer dump-autoload
了解每一步的结果。我假设问题仍然存在，但前3-4步会很好。
可能会考虑将laravel升级到4.1，因为我认为新的codeleeve需要一些东西吗？
tl：dr寻找Codesleeve \ AssetPipeline \ Filters \ CssRewrite，但无法找到它。
