I am using Windows 10 and composer. I'm getting an error when I attempt to install the laravel installer. Any help would be greatly appreciated. Here is the full output when I attempt to install:

For me, the problem was 7zip. Composer was using 7z.exe from Lua (which I had previously installed). When I installed 7z from the official site and updated the PATH variable, this error was solved.
I can't provide an explanation though, I am not sure what happened...

I reinstalled Composer 4 times before making this post. After unsuccessfully trying the solutions above, I tried reinstalling composer again and then ran the laravel/installer - and it worked fine. Thanks to everyone who took the time to reply.

You Have Problem with symfony/polyfill
Delete Manually Vendor and composer.lock

Or
Cleaning composer cache worked for me:

composer clearcache

Then Install your package

This usually happens when the files are corrupted in your local environment. Try removing cache and re-installing the packages

$ composer clearcache
$ composer global require laravel/installer
