Well I was able to install it by :

<pre><code>sudo apt-get install php-curl

on my system. This will install a dependency package, which depends on the default php version.

After that restart apache

I tried the above solutions but it didn't work for me, just incase there any other person in the same shoes, this is what I did.
I updated apt-get with the following command

this i installed with php curl for the version of php that i was using, mine was

If You have 404 or errors while <code>sudo apt-get install php-curl</code> just try

<pre><code>sudo apt-get update
</code></pre>

and again try

<pre><code>sudo apt-get install php-curl
</code></pre>

But notice what version was installed (i use php7.3 and php7.4-curl was installed - so it will not work)

try then

<pre><code>sudo apt-get install php7.3-curl
</code></pre>

At the end You may want to restart services like: apache2 or php-fpm:

<pre><code>sudo apache2 restart
sudo service php7.3-fpm restart
</code></pre>

this worked for me.

Check if curl is on the installed modules list for current php:

<pre><code>php -m
</code></pre>

With PHP 5, you can easily install it by running the <code>yum</code> or <code>apt-get install php5-curl</code> command, but I can't find how to install the PHP 7 equivalent.

How do I install ext-curl for PHP 7?

我已经使用安装了PHP7，但是当我尝试运行composer install时，它给出了这个错误：PHP 包需要ext-curl * ->您的系统中缺少请求的扩展名curl。在PHP5中，您可以通过运行yum或apt-get install php5-curl命令轻松地安装它，但是我找不到如何安装PHP7的等价物。如何为PHP7安装ext-curl？
