我正在尝试将干预映像安装到我的Laravel 5应用中。以下是我的composer.json我的require：
"require": {
"laravel/framework": "5.0.*",
"laravel/cashier": "~3.0",
"barryvdh/laravel-debugbar": "~2.0",
"illuminate/html": "5.0.*@dev",
"intervention/image": "~2.2@dev"
}
运行composer update时，我会发现一个错误：Your requirements could not be resolved to an installable set of packages.
可以在下面找到作曲家的全部输出。我想指出，作曲家是最新版本（使用composer self-update）。
mikemike@workspace:~/workspace/workspace (master) $ composer update

我在require行内尝试了一些不同的值，包括dev-master，并且我尝试通过单个作曲家行安装，这两者都会给出相同的错误（php composer.phar require intervention/image）。
您的问题：
- Installation request for way/generators ~2.0 -> satisfiable by way/generators[2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.6.1].
- way/generators 2.6.1 requires illuminate/support ~4.0
由于illuminate/support是laravel/framework中包含的软件包，因此必须匹配它们的版本。在您的情况下，需要laravel/framework的5.0.*和illuminate/support的~4.0（4.*）。这些不匹配，无法安装依赖项。
这意味着您必须使用Laravel 4或找到其他包裹。（或其他支持Laravel 5的way/generators的版本）。
