Question

我正在尝试生成发票pdf，因此我使用KnpSnappyBundle而不是symfony2＆amp; twig从html生成pdf

在我的ubuntu上，一切正常，在生产环境中（FreeBSD，共享主机）我收到一个我不明白的错误。我的配置

knp_snappy:
    pdf:
        enabled:    true
        binary:     "%kernel.root_dir%/../bin/wkhtmltopdf-i386"
        options:    
            lowquality: false
            encoding: UTF-8
    image:
        enabled:    false
        binary:     "%kernel.root_dir%/../bin/wkhtmltoimage-i386"
        options:    []
    temporary_folder: %kernel.cache_dir%/snappy

错误

我已将html缩减为“Hello PDF”，我尝试了不同的软件包和不同的配置。但他们都是基于wkhtmltopdf。这里有任何帮助，这点是从html生成PDF。谢谢stackoverflowers
