我正在尝试通过composer在laravel v5.8.4中安装Form＆Html软件包，但无法正常工作。我每次都会收到此错误。我尝试使用Google搜索解决方案，但都失败了。总是相同的错误。
我正在尝试安装"laravelcollective/html": "~5.0"。 composer update和composer require ...两种方式都尝试过

答案 0 :(得分：2)
还原您的composer.json和composer.lock文件
尝试后
composer require laravelcollective/html
它将安装最新版本，并且与laravel 5.8
您正在尝试使用与"laravelcollective/html": "~5.0"不兼容的特定标签安装laravel 5.8
答案 1 :(得分：0)
能否请您使用laravelcollective / html“：”〜5.0“软件包检查其是否支持Laravel 5.8。如果您的软件包中的任何一个与laravel 5.8版本都不匹配，则会显示此错误。请添加适当的版本并运行作曲家更新。它肯定会起作用...
