Answer 1

I'm on a Windows machine and I tried all of the answers from this question, but none of them worked. For me, it FINALLY worked after I ran composer using the 64-bit version of PHP.

To run composer using a local copy of PHP x64 you can do the following:

1. Download the zip file from here (I used the VC15 x64 Thread Safe version): https://windows.php.net/download
2. Unzip the file
3. Copy php.ini-development and rename to php.ini
4. Uncomment the extension_dir = "ext" line and any other php extensions you will need (such as extension=gd2 or extension=openssl). If any other PHP extensions are needed for the update then it will tell you while running the command.

Working command:

"C:\path\to\php-7.2.23-Win32-VC15-x64\php.exe" -d memory_limit=-1 "C:/path/to/composer.phar" update
