laravel 如何安装jonnyw/php-phantomjs

我安装 jonnyw/php-phantomjs 时候老是报错，

• jonnyw/php-phantomjs[v4.3.0, …, v4.6.1] require symfony/yaml 2.3|3.0 -> satisfiable by symfony/yaml[v2.3.0, …, 2.8.x-dev, v3.0.0-BETA1, …, 3.4.x-dev].
  • jonnyw/php-phantomjs[v4.0.0, …, v4.2.1] require symfony/yaml ~2.3 -> satisfiable by symfony/yaml[v2.3.0, …, 2.8.x-dev].
  • symfony/routing v5.4.8 conflicts with symfony/yaml v3.4.47.
  • symfony/routing v5.4.8 conflicts with symfony/yaml v3.4.46.
    包与包之间冲突了
    如何安装呢

主要是我不会python，然后要去爬些数据，我就搜到这个插件，发现还装不上去？
