Magento2: Installation fails on Magento_Indexer step

[wojtekn]

Installation fails for me on Magento_Indexer step with following fatal error:

"PHP Fatal error:  Cannot instantiate interface Magento\Framework\Indexer\ConfigInterface"

I use latest develop branch on OS X with Apache 2.4.16, PHP 5.5.18 and MySQL 5.6.21. I'm running installation with not existing app/etc/config.php file, empty database and var/cache/* and var/generation/*cleared.

Command I use looks as follows:

./magento setup:install --base-url=http://local.magento2.com/ --backend-frontname=admin --db-host=127.0.0.1 --db-name=magento2 --db-user=magento2 --db-password=PASSWORD --admin-firstname=John --admin-lastname=Doe [email protected] --admin-user=johndoe --admin-password=johndoe1 --language=en_US --currency=USD --timezone=Europe/Warsaw

It fails for me every time when I start fresh installation. However, when it fails, I'm able to go through this by cleaning var/cache/* and running same installation command again.

Full stack trace looks as follows:

@wojtekn thank you for reporting. we have created MAGETWO-43238 to investigate. Also, can you tell us what mode are you operating in?

[wojtekn]

@mazhalai at the beginning I thought it occurred only with "developer" mode enabled, but I reproduced this in "default" mode as well.

[mazhalai]

@wojtekn we are unable to reproduce this error. Have you tried clearing you var directory and trying again? Also, can you please give us more details about PHP version, server configuration etc.

[wojtekn]

@mazhalai thanks for checking this. Finally I found a way to reproduce and it looks it's not an issue.

I'm able to reproduce this error when I try to reinstall Magento 2 after removing following:

• var/*
• app/etc/config.php
• database content

I can't reproduce it when I also remove app/etc/env.php.

Now I see manual recommends using bin/magento setup:uninstall to uninstall Magento and that tool removes env.php as well. It looks issue appeared as I haven't uninstalled Magento properly.

@wojtekn thank you for your follow up. I am closing this issue. Please feel free to open a new one.

[johnverzijden]

Had the same problem. Removing the var directory solved it.

[jerome-breton]

Clearing the cache solved the problem for me. In my case, I was using redis and removing /var was obviously not enough.
