【问题描述】：

我正在将 Laravel 与 docker php:7.3-fpm 图像一起使用。

当我像这样使用Image Intervention Package 时遇到问题Call to undefined function Intervention\Image\Gd\imagejpeg()"：

$avatar = \Image::make($image->getRealPath());
$avatar->fit(221, 146)->encode('jpg', 80);

这是完整的错误信息：

exception: Symfony\Component\Debug\Exception\FatalThrowableError^ #8221
      -originalClassName: "Error"
      #message: "Call to undefined function Intervention\Image\Gd\imagejpeg()"
      #code: 0

          arguments: 
            $format: "jpg"
            $quality: 80
          
        

Gd/Encoder.php 的第 17 行是这样的：

imagejpeg($this->image->getCore(), null, $this->quality);

我发现here 我应该安装支持 jpg / png 的 GD。但是，there 的答案是针对 php:7.2-fpm-alpine 图像的。由于我不使用图像，因此无法将其应用于apk add libjpg .. 解决方案。

我还发现here 使用PHP:7.2-fpm 图像并声称可以修复jpg 问题。

我用过

RUN apt-get install -y build-essential libssl-dev zlib1g-dev libpng-dev libjpeg-dev libfreetype6-dev

和

RUN docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd

来自该解决方案，但我仍然收到上述错误。这是我完整的 Dockerfile：

FROM php:7.3-fpm

RUN mkdir -p /home/$user/.composer && \
    chown -R $user:$user /home/$user

# Set working directory
WORKDIR /var/www

USER $user

知道是什么原因造成的吗？

【问题讨论】：

php -m 告诉你什么？模块是否安装？如果您依赖打包的扩展，则不需要安装所有这些开发库，只需 apt-get install php7.2-gd

@miken32 gd 列在包中。我也通过RUN docker-php-ext-install ... gd ... 安装了它。我仍然收到Call to undefined function Intervention\Image\Gd\imagejpeg()"

请把你的代码块发给我们。 imagejpeg() 是全局的，不是命名空间的，所以它可能是代码中的问题。

@ŁukaszJakubek 我添加了代码部分，尽管归结为使用imagejpeg。

@ŁukaszJakubek 同样，此代码在使用 Homestead 和 Vagrant 时有效 - 因为我试图切换到 docker，所以它只是失败了。

【参考方案1】：

缺少这一行：

RUN docker-php-ext-install -j$(nproc) gd

所以我最终的 dockerfile 看起来像这样：

FROM php:7.3-fpm

ARG user
ARG uid

    build-essential \

    libicu-dev \
    zip \
    unzip \
    libzip-dev \
    -y mariadb-client
