我正在尝试通过composer 在Ubuntu 16.04 上安装laravel，现在这样做时出现错误：

 To enable extensions, verify that they are enabled in your .ini files:

    - /etc/php/7.2/cli/conf.d/20-xmlwriter.ini
    - /etc/php/7.2/cli/conf.d/20-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

我有php-7.0 版本，我更新到php-7.2 版本。我也对这些进行了安装：

sudo apt-get install php7.2-fpm php7.2-curl php7.2-mysql php7.2-gd php7.2-xml php7.2-mcrypt php7.2-mbstring php7.2-iconv

我想安装时缺少一些东西。

帮我解决这个问题。谢谢

尝试注销并登录。然后用谷歌搜索stackoverflow.com/questions/35815376/…
我建议您使用 xampp 来避免此类错误。
你删除了php7.0吗？
@RahulShrivastava 我一直使用 ubuntu，我可以向你保证我从来没有遇到过这些错误
愚蠢的注意，但你的安装字符串实际上并没有安装 php7.2 只为 php 7.2 扩展

标签： php laravel php-7 php-7.2

【解决方案1】：

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.2-cli

等等

service nginx restart # or service apache2 restart
