Fatal error: Cannot redeclare Amp\delay() (previously declared in /Users/adam/projects/oursite/vendor/amphp/amp/src/functions.php:63) in /Users/adam/.composer/vendor/amphp/amp/lib/functions.php on line 133

I've started getting this recently. I'm not sure what could have changed to cause this to start happening.

I have grumphp installed globally via composer on my computer and I have it installed in each of our projects via composer for ci and ide purposes. I suspect that's why I'm getting the error when I run composer install on those projects. It also throws when I run grumphp commands in those projects.

Running /vendor/bin/grumphp works fine when run explicitly, but when run as a git hook or composer hook, it seems to be the same as executing the grumphp alias.

My configuration

grumphp:
    tasks:
        composer: ~
        phplint: ~ 
        yamllint: ~
        phpcs:
          standard: "phpcs.xml.dist"
        securitychecker_composeraudit: ~
        git_commit_message: 
            matchers:
                Must use the following format (jira project, dash, jira number, space, commit message): "/(\\w+)-\\d+:\\s+.+/"
            max_subject_width: 120
            max_body_width: 255

Steps to reproduce:

• Install grumphp via composer globally
• Install grumphp via composer in a specific project, including allow-plugins
• Run composer install or grumphp -v

Workaround:

• composer global remove phpro/grumphp

Hi @loopy3025, You can install GrumPHP using the 'shim' version. This is a separate packaged version so you don't have a conflicting dependencies: https://github.com/phpro/grumphp-shim

Thanks, I'll check that out.

@BrentRobert Installing phpro/grumphp-shim globally has worked perfectly. Thank you.
