php - Erros使用PHP和Twig镜像Docker

Question

我在docker上安装Synfony和Twig时遇到问题。

Fatal error: Uncaught Error: Class 'Twig \ Environment' not found in /var/www/html/... appears.

这是我的Dockerfile

FROM php: 7.2-apache

#Install unzip, composer,
RUN curl -sS https://getcomposer.org/installer | php - --install-dir = / usr / local / bin --filename = composer \
    && apt-get update && apt-get install -y git libzip-dev unzip \
    && docker-php-ext-install zip \
    && a2enmod rewrite headers \

COPY src / / var / www / html /
    
#Enable Twig and Symfony
RUN cd / var / www && composer require "twig / twig: ^ 3.0"
RUN composer require "symfony / form"

我的 Controller

protected function load (string $ view, $ param = [])
{
    $twig = new \Twig\Environment((new \Twig\Loader\FilesystemLoader ('../app/site/view/')),
        ['debug' => false]
    );
    $ twig->addGlobal ('BASE', BASE);
    echo $twig->render($view . '.twig.php', $params);
}

你知道怎么了吗

请原谅，我对错误的关注如此之大，以至于错误未被注意到。
我在错误的文件夹中运行 Composer

COPY src/ /var/www/html/

RUN cd/var/www && composer require "twig/twig:^3.0"

它在www上运行，但应用程序在www / html上
对不起...
