phplaravelcomposer-phplaravel-5.5laravel-horizon

How can I solve "laravel/horizon v1.1.0 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system"?


When I run composer install on command promp, there exist error like this :

  Problem 1
    - Installation request for laravel/horizon v1.1.0 -> satisfiable by laravel/horizon[v1.1.0].
    - laravel/horizon v1.1.0 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system.

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\xampp-7.1\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

How can I solve this error?


Solution

  • Run composer with the --ignore-platform-reqs option and specify pcntl and posix

    composer install --ignore-platform-reqs
