尝试在laravel 5.1 mac上安装php phantom js时，Composer安装错误

Question

我试图在laravel 5.1上安装php幻影js，但不断得到一个奇怪的错误：

“Class PhantomInstaller \ Installer不能自动加载，无法调用post-install-cmd脚本”

我已经将以下内容写入我的composer.json文件，在我的root中添加了一个bin文件夹，然后运行composer install，但无济于事：

"require": {
        "jonnyw/php-phantomjs": "3.*"
    },
    "config": {
        "bin-dir": "bin"
    },
    "scripts": {
        "post-install-cmd": [
            "PhantomInstaller\\Installer::installPhantomJS"
        ],
        "post-update-cmd": [
            "PhantomInstaller\\Installer::installPhantomJS"
        ]
    }

有谁知道什么可能是错的？

有相同的错误，通过安装@dev版本修复。

这是我的composer.json，它工作正常。
