I am creating a new project in Laravel 5.8 and I also want to install Telescope, but when I execute the command in my project:

composer require laravel/telescope

output:

./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.2/cli/php.ini
    - /etc/php/7.2/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.2/cli/conf.d/10-opcache.ini

    - /etc/php/7.2/cli/conf.d/20-xsl.ini
    - /etc/php/7.2/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.

Installation failed, reverting ./composer.json to its original content.

How can I install the missing dependencies? I'm working on PHP 7.2 and ubuntu 18.04.2.

You will have to install the bcmath extension. In your case, it can be done by running

sudo apt-get install php7.2-bcmath

sudo apt-get install php7.1-bcmath if you have PHP 7.1

Then run the require command again.
