我对应用程序的本地版本安装此软件包没有问题。

首先，阅读警告！它说做不是运行作曲者为根！其次，你可能在你的本地使用了Xammp，默认情况下需要php库。

但在您的服务器上，您缺少ext-dom。 php7.1-xml有你需要的所有相关软件包。所以，你可以简单地通过运行安装它：

sudo apt-get update 
sudo apt-get install php7.1-xml

最有可能你失踪mbstring太。如果你得到错误，安装该软件包以及与：

sudo apt-get install php-mbstring

然后运行：

composer update 
composer require cviebrock/eloquent-sluggable

感谢。如果我不使用'sudo'来运行作曲家，可以得到这个错误：'无法读取/home/pish/.composer/auth.json file_get_contents（/home/pish/.composer/auth.json）：无法打开流：权限被拒绝' – alex

它的权限问题搜索chmod和chown命令。更改此文件夹的权限和所有者，你会没事的。 –

@rodrane你的代码中存在一个用于安装'php-mbstring'软件包的错误，它应该是'sudo apt-get'。除此之外;它的作用就像一种魅力。谢谢！ –
