I have a VM running Magento 2 with the sample data that was installed not using composer - I grabbed the latest version from the Magento site). The site itself runs fine, but when I try to run anything for the command line, I get this error:

PHP Fatal error:  Uncaught Error: Class 'Magento\Setup\Mvc\Bootstrap\InitParamListener' not found in /var/www/html/public/setup/config/application.config.php:24
Stack trace:
#0 /var/www/html/public/vendor/magento/framework/Console/Cli.php(57): require()
#1 /var/www/html/public/bin/magento(22): Magento\Framework\Console\Cli->__construct('Magento CLI')
#2 {main}
  thrown in /var/www/html/public/setup/config/application.config.php on line 24

I built the VM on another machine using build scripts, and then used those to build it on this machine, and it worked for a bit, but I suspect I left something out of source control that would be causing this.

Check that the composer.json file in the Magento root directory is not corrupted / overwritten. You can compare it with the official composer.json file from https://github.com/magento/magento2

I got a very similar issue with the following error;

Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for Magento\Setup\Mvc\Bootstrap\InitParamListener

I was able to solve this by deleting the contents of vendor and then re-running composer install

I can see that something is running inside the vendor folder:

#0 /var/www/html/public/vendor/magento/framework/Console/Cli.php(57)

Please, try:

composer self-update && composer update

    I did that earlier and it wiped out my magento install. My composer.json only has this: { "repositories": { "magento": { "type": "composer", "url": "repo.magento.com" } } }. I assume that has to do with the fact that I didn't use composer to install Magento?

  • Yes @Laura , probably. Sorry, I did not pay attention to the part of your question that had not used composer.. Got a solution for this? Mar 3, 2017 at 17:59
  • This wiped out the entire Magento install
