wkhtmltopdf：更新了我的 Ubuntu 服务器并获得了 "QXcbConnection: Could not connect to display"

Question

带有 'phpwkhtmltopdf' 的东西停止工作。

运行在网络浏览器上使用此代码：

    $string = "http://www.google.com";

    // You can add parameter for the constructor call
    $binary = '/usr/bin/wkhtmltopdf';

    $pdf = new Pdf(array(
        // Explicitly tell wkhtmltopdf that we're using an X environment
        // 'use-xserver',
        // Enable built in Xvfb support in the command
           'commandOptions' => array(
           'enableXvfb' => true,
            // Optional: Set your path to xvfb-run. Default is just 'xvfb-run'.
            'xvfbRunBinary' => '/usr/bin/xvfb-run',
            // Optional: Set options for xfvb-run. The following defaults are used.
            //'xvfbRunOptions' =>  '--server-args="-screen 0, 1024x768x24"',
        ),
    ));

    $options = array( 
        // 'page-width' => '216mm', 
        // 'page-height' => '279mm', 
        'page-size' => 'A4', 
        //'dpi' => 96, 
        //'image-quality' => 100, 
        //'disable-smart-shrinking', 
        //'no-outline', 
        //'no-outline',           // option without argument
        'encoding' => 'UTF-8',  // option with argument
        'user-style-sheet' => $cssPath,
        'margin-top'    => 0,
        'margin-right'  => 0,
        'margin-bottom' => 0,
        'margin-left'   => 0
        // 'orientation' => 'portrait', 
        // 'images' => true,
        // 'cookie' => array(),
         //'dpi' => 1000
        // 'image-dpi' => 300
        // Default page options 
        // 'enable-smart-shrinking'
        );

    //$pdf->setOptions( $options );

    $pdf->binary = $binary;
    $pdf->addPage($string);
    $pdf->saveAs(FCPATH."files/weekly_reports/$prod_id-Weekly-Report.pdf");
    var_dump($pdf);

我开始加载加载加载加载...我的 putty windows 开始工作非常慢，使处理器跳到 100%。一切都卡住了，直到我设法 service apache2 restart 或重新启动 virtualbox。

运行在 CLI 上： wkhtmltopdf http://google.com google.pdf

我得到这个输出：

QXcbConnection: Could not connect to display
Aborted (core dumped)

我唯一做的就是 dist-update 和升级。 PHP5改为7。可能是什么问题？可能有一个包裹被意外删除了？到现在为止一切正常。

当我在 CLI 上运行时： xvfb-run wkhtmltopdf http://google.com test.pdf

顺便说一下，它有效..

Answer 1

找到问题了。有一个 CSS SRC 是错误的...

Answer 2

$binary = '/usr/bin/xvfb-run -- /usr/bin/wkhtmltopdf';
