PHP7：安装ext-dom问题

168

我在使用PHP7的Ubuntu 16.04服务器上运行laravel 5.4。尝试安装cviebrock/eloquent-sluggable软件包会引发一些错误：

pish@let:/home/sherk/ftp/www$ sudo composer require cviebrock/eloquent-sluggable
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^4.2 for cviebrock/eloquent-sluggable
./composer.json has been updated

  Problem 1
    - phpunit/php-code-coverage 4.0.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.

我在应用程序的本地版本上安装此软件包没有问题。

首先，请阅读警告！它说，你不跑作曲家根！其次，您可能在本地使用Xammp，默认情况下具有所需的php库。

但是在您的服务器中，您不见了ext-dom。php-xml拥有您需要的所有相关软件包。因此，您只需运行以下命令即可安装它：

sudo apt-get update
sudo apt install php-xml

您很可能也失踪mbstring了。如果收到错误，请同时安装此软件包：

sudo apt-get install php-mbstring

然后运行：

composer update
composer require cviebrock/eloquent-sluggable

谢谢 。如果我不使用sudo运行作曲家，则会收到此错误：Could not read /home/pish/.composer/auth.json file_get_contents(/home/pish/.composer/auth.json): failed to open stream: Permission denied

搜索chmod和chown命令是一个权限问题。更改此文件夹的权限和所有者，就可以了。

@rodrane您的代码中有一个错字用于安装php-mbstring软件包，应该是sudo apt-get。除此之外; 它就像一个魅力。谢谢！

我在机器上安装了php7.0-xml，但是当我执行以下操作时，作曲家仍然会向我抛出此错误composer install
— Salustiano Muniz
@SalustianoMuniz您可能必须启用PHP中的模块。例如，sudo phpenmod xml对xmlreader＆使用和做相同的事情xmlwriter。然后重新启动服务器（如果是apache：），sudo service apache2 restart然后尝试重新安装。

对于想要在php 7.1上安装ext-dom的用户，请运行以下命令：

sudo apt install php-xml

这在Ubuntu 18.04上对我有用-迄今为止最好的答案。
— 拂尘
这个答案的问题是它使用当前设置的默认php版本。例如说我sudo update-alternatives --set php /usr/bin/php7.0，php-xml会下载php7.0-xml。使用这种方法时要谨慎，我总是建议更换@anar的做法
— ：曹淑红
但是该示例清楚地表明OP要求的是7.0版本，但未遵循所选答案。这是异常现象。不过，了解版本确实有意义。

对于CentOS，RHEL，Fedora：

$ yum search php-xml

然后选择与您的php版本匹配的php-xml版本：

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

sudo apt install php-xml 可以使用，但问题是它将下载最新PHP版本的插件。

如果您的PHP版本不是最新的，则可以在其中添加版本：

# 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 (latest)
sudo apt install php-xml
