Try deleting the contents of vendor and then in the terminal change into the root magento directory which should have composer.json.

Run composer install. If composer install fails, it will be because composer.lock is not up-to-date, so you should run composer update.

  • what i did was, just deleted all files form vendor, and run composer install, all files auto generated in vendor folder, after i try to upgrade i am getting same error what i was getting yesterday.

  • how have you attempted the initial upgrade - in the admin wizard or using the composer.json? Apr 19, 2018 at 9:21
  • what do you get when you run composer update? Apr 19, 2018 at 9:24
  • My composer.json file : justpaste.it/4lpku highlight the line my change.

Your issue is the module : module-wishlist-sample-data, you have two solutions :

  1. You update the module.

  2. You remove the module.

Case 1 (update) :

You run these commands:

  • composer update, php bin/magento setup:upgrade

Case 2 (remove) :

Uninstall module via composer :

  • php bin/magento module:uninstall -r <Vendor>_<Module>, php bin/magento setup:upgrade

Removing it manually :

I do not recommend this way, you can use it just if the other solutions really did not work or that you have removed the module not in the right way or you are stuck !

  1. Remove the module from vendor/{moduleName}

  2. Remove the whole line of module name in these files vendor/composer/:

    • autoload_files.php, autoload_psr4.php, autoload_real.php, autoload_static.php, installed.json
  3. php bin/magento setup:upgrade
