I have php 7.0.29 version installed on my vagrant setup on windows 10.

When I run following command 

composer require --dev phpunit/phpunit

I get errors as mentioned

Using version ^6.5 for phpunit/phpunit
./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.

    }
}

How do I fix it?

  • Either check if PHP 7.0 is high enough for this repository requirements and if so, try to remove the composer.lock file and install again. – hakre Apr 28 '18 at 14:27
  • @hakre I deleted composer.lock file and tried again but it did not help – Mukesh Apr 28 '18 at 18:05
  • Then it looks like that the packages you require are not compatible to each other. Is there anything special requiring these versions? – hakre Apr 29 '18 at 07:47
  • @hakre I don't think I need specific version. I am following a tutorial and first time using php unit as well as composer. Do you have any suggestion to fix this ? – Mukesh Apr 29 '18 at 19:20
  • Please share the full content of your `composer.json`. – rob006 May 03 '18 at 22:04
  • @rob006 I have updated the question with complete composer.json – Mukesh May 04 '18 at 18:44
  • Why are you manually requiring `phpunit/php-invoker` and `phpunit/dbunit`? Shouldn't `phpunit/phpunit` suffice? – k0pernikus May 07 '18 at 09:47

  • I got this error when trying to upgrade my phpunit by requiring it again. Solution for me was to uninstall phpunit and reinstall it: 

          $ composer remove phpunit/phpunit --dev
      $ composer require phpunit/phpunit --dev

You are requiring old versions of:

"phpunit/php-invoker": "^1.1",
"phpunit/dbunit": "^2.0"

Yet phpunit requires more up to date version of those dependencies as it tells you here:

- phpunit/dbunit 2.0.3 conflicts with phpunit/phpunit[6.5.0].
- phpunit/phpunit 6.5.0 conflicts with phpunit/dbunit[2.0.3].
- phpunit/phpunit 6.5.0 conflicts with phpunit/dbunit[2.0.3]

Only require phpunit/phpunit, instead and let composer handle its dependencies instead of requiring each dependency.

I've got the same problem. I did

composer remove symfony/phpunit-bridge --dev

after that, I reinstalled it by doing

composer require --dev symfony/phpunit-bridge

and then

php bin/phpunit
