Failed opening required '/var/www/html/app/autoload.php'

[marvincaspar]

After installing the newest magento version 2.0.2 I get an error while running the installation script.

PHP Warning:  require_once(/var/www/html/app/autoload.php): failed to open stream: No such file or directory in /var/www/html/app/bootstrap.php on line 31
PHP Stack trace:
PHP   1. {main}() /var/www/html/bin/magento:0
PHP   2. require() /var/www/html/bin/magento:15
PHP Fatal error:  require_once(): Failed opening required '/var/www/html/app/autoload.php' (include_path='.:/usr/local/lib/php') in /var/www/html/app/bootstrap.php on line 31

It is strange because compoer install downloads all modules but the mapping from the magento-base module doesn't work. In the app only bootstrap.php, etc/vendor_path.php and design/adminhtml/Magento/... are copied. Files like autoload.php, functions.php are not available in the app folder, but available in vendor/magento/magento2-base/app.

Any ideas whats wrong?

Can you please run

composer -vvv run-script post-install-cmd

and provide the output?

And have you checked if file and directory access rights are properly set-up and you run composer with the correct user? (I assume you installed magento via the command-line, correct?)

Yes I installed magento with cli. Here is the output:

All files are owned by the same user, which is running the composer command

Looks like you're installing as the root-user. As you should

2. Log in to your Magento server as, or switch to, the Magento file system owner.

that would mean your magento file system owner would be root. I hardly doubt that so I assume you did this in error. As that kind of error supersedes your report from severity (IMHO), I'd say must fix the installation user problem first.

Especially as your report is about the composer installer not being able to copy files.

Note: Using the correct user in system setup must not automatically solve your problem but should create a basis on further trouble-shooting your issue.

I tried it locally on my mashine with no root user and get the same result with an other user path

[ktomk]

@mc388: Then it's not the root user.

[marvincaspar]

Locally I'm using my dev user. He is also the owner of all files.
