I am trying to upgrade blt from 8.3 to 8.9 using composer, but I am getting below error.

[suresh-kumara-gist]

My system information:

• Operating system type: [mac]
• Operating system version: []
• BLT version: [8.3]

When I run this command: composer require acquia/blt:^8.9.11 --no-update && composer update

I get the following output:

Seems like Composer is freaking out for some reason. Try composer run-script nuke, or if that doesn't work, manually remove your vendor directory, your lock file, and run composer clear-cache, then run composer update again.

@suresh-kumara-gist Did @danepowell's suggestion resolve your issue?

[suresh-kumara-gist]

thanks for the reply @danepowell.

I manually removed vendor directory, lock file, and run composer clear-cache, then run composer update again, But din't work for me.

I edited this file /usr/local/var/www/myinstance/vendor/composer/autoload_real.php and added

if (file_exists($file)) {} at line 78.

if   (file_exists($file)) {
    if (empty($GLOBALS['__composer_autoload_files'][$fileIdentifier])) {
        require $file;

        $GLOBALS['__composer_autoload_files'][$fileIdentifier] = true;
    }
}

after that run again $ composer require acquia/blt:^8.9.11 --no-update && composer update

worked well for me.

Can confirm removing composer's vendor directory and reinstalling the site dependencies works.

$rm -rf vendor && composer install

[thomasabishop]

Can second @kalevitan. Worked fine and restored site to status quo ante.
