Symfony 3 TwigExtensionAbstractExtension 在生产模式下找不到错误 [英] Symfony 3 TwigExtensionAbstractExtension not found error in production mode
问题描述
我有一个在开发模式下运行良好的应用程序，但是当我在生产环境中运行它时会弹出:
I have an app that runs fine in dev mode, but when I run it in production this pops up:
Fatal error: Class 'TwigExtensionAbstractExtension' not found in C:UserswackmPhpstormProjectspoemvendorsymfonysymfonysrcSymfonyBridgeTwigExtensionLogoutUrlExtension.php on line 23
我猜这与我的自定义树枝扩展有关:
I'm guessing this relates to my custom twig extension:
<?php
// src/AppBundle/Twig/VersionExtension.php
namespace AppBundleTwig;
use AppBundleEntityVersion;
use PhpOfficePhpSpreadsheetCalculationDateTime;
/**
* Class VersionExtension - converts versions to readable HTML.
* @package AppBundleTwig
*/
class VersionExtension extends Twig_Extension
{
/**
* Defines the function name for use in twig templates.
* @return array
*/
public function getFunctions()
{
return array(
new Twig_SimpleFunction('version', array($this, 'versionFunction')),
);
}
/**
* Actual function that converts a Version object into a HTML string.
*
* Indent indents the associated entities within each other, but NOT
* the individual items, it does this by incrementing in 0.5 and truncating
* $indent with intval()
* @param array $hydrated_entity
* @param string $title
* @param indent
* @return string
*/
public function versionFunction($hydrated_entity, $title = null, $indent = 0)
{
$result_html = '';
if (!empty($hydrated_entity) and $title != null) {
$result_html .= '<div style="text-indent:' . (intval($indent) * 20) . 'px"><strong>' . $title . '</strong></div>';
}
foreach ($hydrated_entity as $key => $value) {
// Ignore meta attributes.
if (in_array($key, array("ID", "Updated At", "Created At"))) {
continue;
}
if (is_array($value)) {
$result_html .= $this->versionFunction($value, $key, ($indent + 0.5));
} else {
$value = $this->tidyValue($value);
if ($this->startsWith($key, "added_")) {
$result_html .= '<div class="bg-success" style="text-indent:' . (intval($indent) * 20) . 'px">' . explode("_", $key)[1] . ': ' . '<p>' . $value . '</p>' . '</div>';
} else if ($this->startsWith($key, "removed_")) {
$result_html .= '<div class="bg-danger" style="text-indent:' . (intval($indent) * 20) . 'px">' . explode("_", $key)[1] . ': ' . '<p>' . $value . '</p>' . '</div>';
} else {
$result_html .= '<div class="bg-info" style="text-indent:' . (intval($indent) * 20) . 'px">' . $key . ': ' . '<p>' . $value . '</p>' . '</div>';
}
}
}
return $result_html;
}
/**
* Tidies up value for display.
* @param $value
* @return string
*/
private function tidyValue($value)
{
// Convert DateTime to String.
if ($value instanceof DateTime) {
$value = $value->format('Y-m-d');
} else if (is_bool($value)) {
$value = ($value) ? 'true' : 'false';
} else if (is_string($value)) {
//Remove extra <p> tags if present.
$value = preg_replace('!^<p>(.*?)</p>$!i', '$1', $value);
}
return $value;
}
/**
* Checks whether a string begins with a another string.
* @param $haystack
* @param $needle
* @return bool
*/
private function startsWith($haystack, $needle)
{
$length = strlen($needle);
return (substr($haystack, 0, $length) === $needle);
}
}
扩展是否应该扩展 LogoutUrlExtension.php 以外的其他内容?试图扩展它似乎是一个奇怪的文件.PHPStorm 警告我 Twig_Extension 有多个定义，所以我认为这是相关的.
Should the extension be extending something else other than LogoutUrlExtension.php? It seems like a weird file for it to be trying to extend. PHPStorm has warned me that Twig_Extension has multiple definitions, so I'm thinking this is related.
我使用的是 Twig 1.8.
I'm using Twig 1.8.
谁能提供任何见解?

推荐答案
SymfonyBridgeTwigExtensionLogoutUrlExtension 扩展 TwigExtensionAbstractExtensionAbstractExtension(其中你好像不见了).
SymfonyBridgeTwigExtensionLogoutUrlExtension extends TwigExtensionAbstractExtensionAbstractExtension (which seemed to be missing for you).
该文件是 twig/extensions 包的一部分，因此 composer require twig/extensions 应该可以解决问题.
That file is part of the twig/extensions package, so composer require twig/extensions should to the trick.
我不知道为什么 Symfony Twig Bridge 不需要 twig/extensions.(packagist.orgrequires 部分> 只提到 twig/twig)
Why twig/extensions isn't required by the Symfony Twig Bridge I don't know. (The requires section on packagist.org only mentions twig/twig)
