PHP7: install ext-dom问题

我用PHP7在Ubuntu 16.04服务器上运行laravel 5.4。安装cviebrock/eloquent-sluggable包时抛出一些错误:

pish@let:/home/sherk/ftp/www$ sudo composer require cviebrock/eloquent-sluggable

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

我在本地版本的应用程序上安装这个包没有问题。

首先，阅读警告!它说不要运行作曲家根! 其次，您可能在本地使用Xammp，而Xammp默认具有所需的php库。

但是在你的服务器中你缺少ext-dom。Php-xml有您需要的所有相关包。所以，你可以简单地通过运行:

sudo apt-get update
sudo apt install php-xml

很有可能你也丢失了mbstring。如果你得到错误，安装这个包以及:

sudo apt-get install php-mbstring

然后运行:

composer update
composer require cviebrock/eloquent-sluggable

sudo apt install PHP -xml可以工作，但问题是它会下载最新的PHP版本的插件。

如果你的PHP版本不是最新的，那么你可以添加version:

# PHP 7.1
sudo apt install php7.1-xml

# PHP 7.2:
sudo apt install php7.2-xml

# PHP 7.3
sudo apt install php7.3-xml


# PHP 7.4
sudo apt install php7.4-xml

# PHP 8
sudo apt install php-xml

CentOS, RHEL, Fedora:

$ yum search php-xml
============================================================================================================ N/S matched: php-xml ============================================================================================================
php-xml.x86_64 : A module for PHP applications which use XML
php-xmlrpc.x86_64 : A module for PHP applications which use the XML-RPC protocol

php73-php-xml.x86_64 : A module for PHP applications which use XML
php73-php-xmlrpc.x86_64 : A module for PHP applications which use the XML-RPC protocol

然后选择与你的php版本匹配的php-xml版本:

# php -v
PHP 7.2.11 (cli) (built: Oct 10 2018 10:00:29) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

# sudo yum install -y php72-php-xml.x86_64

你只需要更新你的本地作曲文件:

首先你需要删除“作曲家”。锁定”文件从你的应用程序然后，执行你的bash:

composer update --ignore-platform-req=ext-curl

所以再试一次

composer require cviebrock/eloquent-sluggable
