composer安装--no-dev失败，软件包和依赖项不是必需的或已设置，ezsystems/ezplatform依赖

Question

Composer安装失败，出现以下错误：

`Could not load package ezsystems/ezplatform in https://repo.packagist.org: [UnexpectedValueException] Could not parse version constraint dev-load-varnish-only-when-used as ^2.0@dev: Invalid version string "^2.0@dev"`

唯一的问题是，我们不会给那个包打电话...有没有人知道如何找出是哪个包导致了中断？

这是我们的composer.json文件：

  "require": {
    "aws/aws-sdk-php": "^3.92",
    "phpmailer/phpmailer": "^6.0",
    "psr/log": "^1.1",
    "symfony/polyfill-mbstring": "^1.11",
    "guzzlehttp/guzzle": "~6.0",
    "avalara/avataxclient": "*",
    "salesforce-mc/fuel-sdk-php": "*"
  },
  "autoload-dev": {
    "psr-4": {
      "Tests\\": "tests/"
    }
  },
  "require-dev": {
    "php": "^7.0",
    "phpunit/phpunit": "^6.0",
    "fzaninotto/faker": "^1.9",
    "doctrine/dbal": "^2.5",
    "behat/mink": "^1.8",
    "behat/mink-goutte-driver": "^1.2",
    "dmore/chrome-mink-driver": "^2.0",
    "ext-dom": "*"
  },
  "minimum-stability": "dev"
}

Answer 1

此问题已通过以下方式解决：

composer install self-update 1.10.10

前几天作曲家的升级出了点小故障。

另一个修复方法是：

composer install self-update

这将更新到1.10.12并绕过该错误。
