我正在使用Ubuntu 17.04。我试图访问和/etc/php/7.0/cli和编辑php.ini文件。但无论如何都没有帮助。如何启用以下扩展程序。

- phpunit/php-code-coverage 4.0.8 requires ext-dom * -> the requested PHP extension dom is missing from your system.

To enable extensions, verify that they are enabled in your .ini files:
- /etc/php/7.0/cli/php.ini
- /etc/php/7.0/cli/conf.d/10-opcache.ini
- /etc/php/7.0/cli/conf.d/10-pdo.ini
- /etc/php/7.0/cli/conf.d/20-calendar.ini
- /etc/php/7.0/cli/conf.d/20-ctype.ini

- /etc/php/7.0/cli/conf.d/20-tokenizer.ini
- /etc/php/7.0/cli/conf.d/20-zip.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

假设您已成功安装php7.0-cli。
现在在终端中运行以下命令:
sudo apt-get install php7.0-mbstring
sudo apt-get install php7.0-xml
然后尝试再次安装Laravel。
如果您仍然遇到任何问题,请告诉我。

首先为php扩展安装ext-dom,然后再次运行compser update

在安装laravel之前,您可以先完成Laravel所需的依赖项。有关依赖项信息,请参阅here
我可以这样做:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
这里我使用PHP 7.1
sudo apt-get install php7.1
如果您想使用其他版本,请自行更改。
PHP安装完成后,可以继续安装所需的扩展名。
sudo apt-get install php7.1 php7.1-cli php7.1-common php7.1-json php7.1-opcache php7.1-mysql php7.1-mbstring php7.1-mcrypt php7.1-zip php7.1-xml php7.1-gd
上面的扩展应该可以顺利安装laravel。您也可以使用上面的一个或多个扩展名,例如:
sudo apt-get install php7.1-mbstring php7.1-xml
然后重新启动服务器。
希望有用。
