Your PHP need some ext for run your packages.

你的 PHP 需要一些 ext 来运行你的包。

You can install that with apt-get if you use Ubuntu and PHP 5 :

如果您使用 Ubuntu 和 PHP 5，则可以使用 apt-get 安装它：

apt-get install php5-gmp 
apt-get install php5-curl

If you use PHP 7:

如果您使用 PHP 7：

apt-get install php7.0-gmp 
apt-get install php-curl

and etc...

等等...

After that restart your web service then it will work.

之后重新启动您的网络服务，然后它将工作。

First, check if composer is installed by doing.

首先，通过执行检查是否安装了composer。

composer -v

If it is installed, do the following sequence. This worked for me:

如果已安装，请执行以下顺序。这对我有用：

sudo apt-get install php7.2-zip
sudo apt-get install php-mbstring -y
sudo apt-get install php-xml -y

Then finally do this.

然后最后做这个。

composer install

Have you read your error message?

你读过你的错误信息吗？

You are missing two PHP extensions; gmpand curl.

您缺少两个 PHP 扩展；gmp和curl。

You just need to install them, like so:

您只需要安装它们，如下所示：

sudo apt-get install php7.0-gmp
sudo apt-get install php-curl

This should enable them as part of installing them, otherwise you will just need to enable them manually.

这应该在安装它们时启用它们，否则您只需要手动启用它们。

Make sure you restart Apache after installing them - sudo service apache2 reload

确保在安装后重新启动 Apache - sudo service apache2 reload
