我已经通过运行以下命令在容器内手动安装了gd ：

\n\n

apt-get update && apt-get install -y --no-install-recommends \\\nbuild-essential \\\nzlib1g-dev \\\nlibpng-dev \\\n&& docker-php-ext-configure gd --enable-gd && docker-php-ext-install -j$(nproc) gd\n

\n\n

但问题仍然存在，当我这样做时， gd似乎已安装php -m：

\n\n

# php -m\n[PHP Modules]\nCore\ncurl\npdo_mysql\n...\nzlib\ngd\n\n[Zend Modules]\n\n#\n

\n\n

但是当我composer show -p通过我的作曲家容器执行操作时，gd扩展名不会出现：

\n\n

我不知道为什么会这样。我尝试了很多事情但没有成功......

\n\n

这是我Dockerfile的 PHP

\n\n

FROM php:7.4-fpm\n\nWORKDIR /var/www/html\n\nRUN docker-php-ext-install pdo_mysql\n

\n\n

这是我的 php 部分docker-compose.yml：

\n\n

  php:\n    build:\n      context: .\n      dockerfile: Dockerfile\n    container_name: e-learning-app-php\n    volumes:\n      - ./src:/var/www/html\n    ports:\n      - "9007:9000"\n    networks:\n      - laravel\n

\n\n

还有我的作曲家部分：

\n\n

composer:\n    image: composer:latest\n    container_name: e-learning-app-composer\n    volumes:\n      - ./src:/var/www/html\n    working_dir: /var/www/html\n    depends_on:\n      - php\n    networks:\n      - laravel\n

\n\n

帮助。

Answer 1

作曲家需要 maatwebsite/excel --ignore-platform-reqs

试试这个。这对我来说效果很好
