Uncaught Error: Class 'Knp\Snappy\Pdf' not found
mennei opened this issue · comments
Hi,
I have local Apache2.4 on window 10 with php 7.2.4 version.
When I send my html form to the server, I get
Uncaught Error: Class 'Knp\Snappy\Pdf' not found in C:\Apache24\htdocs\bitul-rishum\pdf.php:15
The pdf.php is:
<script src="https://code.jquery.com/jquery-3.3.1.min.js" ></script>
</head>
<body>
<div class="container">
<main><!-- main[white-bg] -->
<?php echo str_replace("https://tk.bitul-rishum.automas.co.il", $dir, $_POST['html']);?>
</main>
</div>
<script type="text/javascript">
$('select').each(function(){
$(this).replaceWith('<span style=" border-bottom: 1px solid #000; display: inline-block; height: 27px; margin-bottom: 5px;" class="text">'+$(this).val()+'</span>');
});
</script>
$snappy->setOption('zoom', '1');
$snappy->setOption('margin-top', '0');
$snappy->setOption('margin-right', '0');
$snappy->setOption('margin-bottom', '0');
$snappy->setOption('margin-left', '0');
$pdfname = uniqid().'_'.time().'.pdf';
$snappy->generateFromHtml($html, $path .$pdfname);
if (file_exists($path.$pdfname)) {
echo $pdfname;
} else {
echo "error";
}
die();
I get the "Uncaught Error: Class 'Knp\Snappy\Pdf' not found in C:\Apache24\htdocs\bitul-rishum\pdf.php:15" message in http response of the post request that made from main.js.
I try to reinstall snappy by "composer require knplabs/knp-snappy", and it failed, saying:
..... can only install on of:....
and the last is:
- Can only install one of: symfony/process[v5.0.4, v4.2.4].
- Installation request for symfony/process (locked at v4.2.4) -> satisfiable by symfony/process[v4.2.4].
Installation failed, reverting ./composer.json to its original content.
- Installation request for symfony/process (locked at v4.2.4) -> satisfiable by symfony/process[v4.2.4].
when I type:
PS C:\Apache24\htdocs\httpdocs\vendor> composer global why symfony/process -t
I get:
Changed current directory to C:/Users/user/AppData/Roaming/Composer
symfony/process v4.4.3 Symfony Process Component
└──laravel/installer v1.5.0 (requires symfony/process ~3.0|~4.0)
└──__root__ (requires laravel/installer ~1.1)
Please help,

Do you need the composer.lock.json?
It seems that your issue is more a composer issue than a Snappy issue.
As far as I know Snappy library is already installed by barryvdh/laravel-snappy and it should be available.
Unfortunately I never used Laravel and I can't help you with that.
What if you remove the vendor directory and you re-install your dependencies with composer install?
Do you get any error?
Thank for your replay :)
You right and the real issue was to run laravel app on plesk server. That solve by php composer install by the web console in plesk.
