Installation Issues

[Wulfheart]

I'm getting the following error when following the installation instructions:

PS> composer require pestphp/pest --dev
Using version ^0.1.5 for pestphp/pest
./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.

  Problem 1
    - Installation request for pestphp/pest ^0.1.5 -> satisfiable by pestphp/pest[v0.1.5].
    - Conclusion: remove phpunit/phpunit 9.0.0
    - Conclusion: don't install phpunit/phpunit 9.0.0
    - pestphp/pest v0.1.5 requires phpunit/phpunit ^9.1.4 -> satisfiable by phpunit/phpunit[9.1.x-dev, 9.2.x-dev, 9.3.x-dev].
    - Can only install one of: phpunit/phpunit[9.1.x-dev, 9.0.0].
    - Can only install one of: phpunit/phpunit[9.2.x-dev, 9.0.0].
    - Can only install one of: phpunit/phpunit[9.3.x-dev, 9.0.0].
    - Installation request for phpunit/phpunit 9.0 -> satisfiable by phpunit/phpunit[9.0.0].

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

Furthermore I'm quite nervous that composer require nunomaduro/collision:"^5.0" --dev --update-with-dependencies isn't available neither.

Did you follow the installation guide? Line by line?

[Wulfheart]

Yes. But I had to edit the version of the collision package.

[canvural]

You have "phpunit/phpunit": "9.0" in your composer json. It means you only allow 9.0 but pest requires 9.1. So I believe if you change it to "phpunit/phpunit": "^9.0" it should work correctly. Unless there is a reason why you are exactly on 9.0

[Wulfheart]

No. I just followed the instructions 🤷🏼‍♂️

[nunomaduro]

Yeah - instructions tell you to change it to "phpunit/phpunit": "^9.0" and not "phpunit/phpunit": "9.0". 👍

[Wulfheart]

Thanks. Now it is working.

However the version of the collision package is unable to get with copy and paste via composer.

[underdpt]

Just a notice here, I also followed the instructions (copy & paste) and ended with composer.json line:

"phpunit/phpunit": "9.0"

Maybe it's a composer issue? (tried with composer 1.10.1 and 1.10.7)

Also failed to install nunomaduro/collision ^5.0, i had to issue:

composer require nunomaduro/collision:"^5.0.0-BETA2" --dev --update-with-dependencies

[owenvoke]

@underdpt, do you happen to be on Windows?

[underdpt]

Yes

[owenvoke]

Yeah, I've had that issue before. ^ is the escape character on Windows command line (at least in Command Prompt), so it ends up just being "9.0" as it escapes the 9.

I'm not really sure what the best way of solving this is. On Windows, it has to be "^^9.0" to escape the escape character.

[alexmartinfr]

Since the caret is a shorthand in composer, maybe we should provide the full syntax it refers to?

composer require phpunit/phpunit:">=9.0.0 <10.0.0" --dev --update-with-dependencies

See composer documentation for "Caret Version Range"
