it appears curl is not enabled in my install, how may I go about it?

    to get the list of all available php modules on my server, I typed

    aptitude search php7-

    No list showed up: Then I typed 

    aptitude search php5-

    and the full list of modules was displayed. Then I ran the command below:

    aptitude install php5-curl

Depending on your distribution, install curl with one of the following:

On CentOS or other yum based package systems

  • yum install php-curl
  • yum install curl

On Debian or other apt-get based package systems

  • apt-get install curl
  • apt-get install libcurl
  • apt-get install php-curl

I haven’t used php7 as of yet. However, as newbie states above, you might try installing curl using apt-get install php7-curl or yum install php7-curl.

Hello,

If you’re using Nginx or Apache on Ubuntu 20 droplet:

Install PHP libraries for the server by running the following command:

sudo add-apt-repository ppa:ondrej/php

sudo apt update

sudo apt install curl

Check the version of curl installed by the command:

dpkg -l curl

You need to restart your webserver on which PHP is running:
If you are using Apache server then use either of the following commands to restart the server:

sudo service apache2 restart

or

sudo /etc/init.d/apache2 restart

Similarly, if you are using Nginx server, then use either of the following commands:

sudo systemctl restart nginx

or

sudo /etc/init.d/nginx restart

Hope that this helps!
Regards,
Alex
