I am getting below error -:

I have solved this problem by just simply doing this steps. follow steps :

  1. Delete the "di" folder located in var directory (for 2.0 and 2.1)
  2. Run this command and go to your project root folder command:

    cd /yourmagentoroot/

    If your Magento mode is developer then you don't need to run below commands just remove var/generation directory(2.0 & 2.1) or generated folder(2.2 onwards)

  3. Then run this command

    php bin/magento setup:di:compile
  4. Then run this command (required in production mode only)

    php bin/magento setup:static-content:deploy
  5. Finally, give file/directory permissions.(If needed)

  • @Gem I think in windows its not needed Feb 21, 2020 at 4:50
  • @gem in linux if your user and php user is different then this issue might arise Feb 21, 2020 at 4:51

Giving full control (read/write/execute) to var and pub directory solved this issue for me.

sudo chmod -R 777 var pub

Or, you may also try running the command using sudo.

sudo php bin/magento setup:upgrade

Also, try clearing cache.

sudo rm -rf var/cache/* var/generation/*
  • In some cases if you have sudo access to magento filesystem owner or webserver user(www-data/nginx). You can execute command like this: sudo -u www-data bin/magento list--

Setup ownership again

CentOS: chown -R :apache .
Ubuntu: chown -R :www-data .

    @murtuza please clear your var/generation folder and cache dirs within var and try again.
