php - UnexpectedValueException 无法解析版本约束 mybranch : Invalid version string "mybranch"

Question

我正在尝试在目录 foo/bar 中使用 Composer 开发一个 PHP 库(称为 /work/a)与 composer.json内容:

{
    "name": "foo/bar",
    "require": {
        "php": ">=7.2"
    }
}

/work/a是一个 git 项目，我在分支 mybranch

我正在尝试在目录 testing/foobar 中使用 Composer 在本地的另一个项目(称为 work/b )中使用此库。与 composer.json内容:

{
    "name": "testing/foobar",
    "type": "project",
    "repositories": [
        {
            "type": "vcs",
            "url": "/work/a"
        }
    ],
    "require": {
        "php": "^7.4",
        "foo/bar": "mybranch"
    }
}

运行时 $ composer install在 /work/b我收到错误:

[UnexpectedValueException]                                            
  Could not parse version constraint mybranch: Invalid version string "mybranch"  

Answer 1

您的分支名称必须以 dev- 为前缀，因此您的分支名称必须是 dev-mybranch。

Loading a package from a VCS repository

...
In composer.json, you should prefix your custom branch name with "dev-".
...

另请查看此 Q/A "Composer require branch name" .

更改分支名称以具有dev- 前缀，将其添加到/work/b 项目中:

{
    "name": "testing/foobar",
    "type": "project",
    "repositories": [
        {
          "type": "vcs",
          "url": "/work/a"
        }
    ],
    "require": {
        "php": "^7.4",
        "foo/bar": "dev-mybranch"
    }
}

运行 Composer 安装:
