php – 通过composer安装Yii2失败

我想通过composer安装yii2,它给了我一个错误

这是错误：

  Your requirements Could not be resolved to an installable set of packages.

  Problem 1
    - yiisoft/yii2 2.0.9 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable | 1.12.*@stable -> no matching package found.
    - yiisoft/yii2 2.0.8 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
    - yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
    - yiisoft/yii2 2.0.6 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
    - yiisoft/yii2 2.0.5 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
    - Installation request for yiisoft/yii2 >=2.0.5 -> satisfiable by yiisoft/yii2[2.0.5, 2.0.6, 2.0.7, 2.0.8, 2.0.9].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

我也安装了最新版本的composer-asset-plugin.
我清除了作曲家缓存并更新它.
但我无论如何都无法安装yii2-basic

这是我的composer.json

{
    "require": {
        "PHPunit/PHPunit": "*",
        "PHPunit/PHPunit-selenium": "*",
        "PHPunit/PHP-invoker": "^1.1",
        "PHPunit/dbunit" : "^2.0",
        "fxp/composer-asset-plugin": "^1.2.0"
    },
    "minimum-stablility‬‬": "dev",
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/Codeception/YiiBridge",
            "reference": "origin/master"
        }
    ],
    "require-dev": {
        "codeception/codeception": "2.2.2",
        "codeception/YiiBridge": "dev-master",
        "flow/jsonpath": "*"
    }
}

解决方法:

由于Yii 2绑定到fxp/composer-asset-plugin,您必须将fxp插件安装到您的composer环境中.必须全局安装fxp插件.您可以使用以下命令实现此目的：

composer global require "fxp/composer-asset-plugin:~1.4"

成功安装fxp插件后,从composer.json中的require部分删除需求,然后再次运行composer update.
