composer-php - Composer 安装后脚本未执行

Question

我正在尝试构建一个包含 PHP 应用程序的 Docker 镜像。

此应用程序通过composer.json安装一些依赖项，并且在安装composer后，需要完成一些自定义(例如，必须将某些文件从供应商文件夹复制到其他位置等)。

因此，我将这些步骤编写为 bash 命令，并将其放入composer.json post-install-cmd 部分中。

这是我的composer.json(我省略了细节，但结构是相同的):

{
  "name": "MyApp",
  "description": "My Service",
  "type": "project",
  "repositories": {
    "a-fancy-library-i-depend-on": {
      "type": "package",
      "package": {
        "name": "a-fancy-library-i-depend-on",
        "version": "1.0",
        "source": {
          "url": "https://github.com/a-fancy-library-i-depend-on",
          "type": "git",
          "reference": "master"
        }
      }
    },
  },
  "require": {
    "symfony/filesystem": "5.2.6",
    "symfony/yaml": "^4.2"
  },
  "require-dev": {
    "a-fancy-library-i-depend-on": "*"
  },
  "scripts": {
    "post-install-cmd": [
      "rm -rf ./src/setup",
      "cp -r vendor/a-fancy-library-i-depend-on/setup/ ./src/setup",
      "mkdir vendor/a-fancy-library-i-depend-on/log"
    ]
  },
  "autoload": {
    "classmap": [
      "src/"
    ]
  },
  "config": {
    "allow-plugins": {
      "a-fancy-library-i-depend-on/composer-module-installer": true
    }
  }
}

在我的 Dockerfile 中，我包含了运行 Composer 安装的步骤:

FROM php:7.4.20-fpm

RUN apt-get update && apt-get install -y git zlib1g-dev libzip-dev libpng-dev libicu-dev g++ zip unzip

RUN docker-php-ext-install zip gd intl

RUN docker-php-ext-configure intl

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

ADD code /code

WORKDIR /code

RUN composer install

问题是“安装后”脚本未执行。

镜像构建成功，但安装文件夹为空。

如果我从此镜像运行容器并在其上输入 bash

 docker container run -ti my-image:local bash

然后我尝试运行

# composer install

瞧!脚本被执行。

这是构建镜像命令的 Composer 安装阶段输出:

如何调试这个问题？

Answer 1

请查看 Composer scripts 的文档。它解释得非常明显:

post-install-cmd: occurs after the install command has been executed with a lock file present.

如果您使用composer install时不存在锁定文件(如控制台输出所示)，则不会触发此事件。
