Composer Json 正则表达式模式验证错误 ^[a-z0-9]([_.-]?[a-z0-9]+)/[a-z0-9](([_.] ?|-{0,2})[a-z0-9]+)$

Question

所以我尝试将 composer 和 laravel 安装到 Phpstorm 中，但现在似乎在 php 中安装 composer.json 文件时出现问题。 PHP 版本为 7.4.8。错误码如下图

   "./composer.json" does not match the expected JSON schema:
    - name : Does not match the regex pattern ^[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9](([_.]?|-{0,2})[a-z0-9]+)*$

我试图查找它以寻求帮助，但它并没有让我走得足够远，所以我想知道是否有人可以帮助我解决这个问题。

这就是我的 composer.json 的样子。

{
  "name": "vendor_name/PhpProjec",
  "description": "description",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "***",
      "email": "email@example.com"
    }
  ],
  "require": {
    "barryvdh/laravel-ide-helper": "v2.7.0"
  }

Answer 1

您可能正在使用 Composer v2 吗？当我使用 Composer v1 在我的本地环境中使用给定的 JSON 时，它告诉我：

Deprecation warning: Your package name vendor_name/PhpProjec is invalid, it should not contain uppercase characters. We suggest using vendor_name/php-projec instead. Make sure you fix this as Composer 2.0 will error.

我的系统上没有出现您提供的错误消息。如果您使用其他包名后仍然遇到问题，请分享更多详细信息

Answer 2

composer 从 v1.9 开始区分大小写... 所以将“PhpProject”更改为“phpproject”

   {
  "name": "vendor_name/phpproject",
  "description": "description",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "***",
      "email": "email@example.com"
    }
  ],
  "require": {
    "barryvdh/laravel-ide-helper": "v2.7.0"
  }

Answer 3

问题出在“名称” 属性

- name : Does not match the regex pattern ^[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9](([_.]?|-{0,2})[a-z0-9]+)*$

相应地更改“名称”属性"vendor-name/project-name"

例如："name": "nismi/my-php-project"

Answer 4

轻松修复转到 composer.json 文件查找大写的位置，例如 Izupay/PayMent 到 izupay/payment 这将修复错误。

{
  "name": "IzuPay/PayMent",
  "description": "description",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "***",
      "email": "email@example.com"
    }
  ],
  "require": {
    "barryvdh/laravel-ide-helper": "v2.7.0"
  }

有效答案是：

{
  "name": "izupay/payment",
  "description": "description",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "***",
      "email": "email@example.com"
    }
  ],
  "require": {
    "barryvdh/laravel-ide-helper": "v2.7.0"
  }

Answer 5

这很可能与您使用的 Composer 版本有关。

在 Composer 2.0 版之前，名称可以包含任何字符，包括空格。

但是，从 2.0 版开始：

名称可以由以 -, 分隔的单词组成。或 _.
完整名称应匹配 ^a-z0-9/a-z0-9$.
名称必须小写（所以不是 vendor_name/PhpProjec，而是 vendor_name/phpprojec
