Composer Fatal error: Cannot redeclare composerRequire

Question

When running the PHP Development server on my MacOS I get the following error from composer.

Fatal error: Cannot redeclare composerRequire01a3dc0b1f885ed2b645be37711584c1() 
(previously declared in /Users/<user>/Desktop/<app>/vendor/composer/autoload_real.php:63) 
in /Users/<user>/Desktop/<app>/vendor/composer/autoload_real.php on line 70

However when running this exact same code on my Windows box everything seems to run perfectly fine. I've verified that I am not including the require statement for the autoload more than once. What could be causing this? I'm using the Composer from HomeBrew if that makes any difference. I just can't see how such a specific file namespace as that could be getting included multiple times.

EDIT

Composer autoload_real.php

Brython

can you paste the /vendor/composer/autoload_real.php generated by composer here? – Unlicensed

@Unlicensed Added – Brython

Why those class and function names tho? – Voe

I haven't touched this, I simply copied whats in the file. I'd assume Composer generated this on its own. – Brython

Answer 1

It seems you made a copy of an existing project directory and try to tun it in a new directory

Try to delete composer.lock and vendor/ and run composer update

I'm not 100% sure but hope it will help
