我尝试使用以下命令在docker中安装GD扩展，但它无法安装。你能告诉我问题出在哪里吗？下面是Dockerfile中的代码。我想安装更多的PHP扩展，如zip也。但我也没有得到任何错误，当我使用 composer 更新命令本身

Codes in Dockerfile
FROM php:7.4-apache
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    && docker-php-ext-install -j$(nproc) gd

下面是yml文件中的代码
