I can not install magento2

[cfcnn]

My environment: centos 6.7, php 5.5.30, nginx 1.8.0, mariadb 10.0.17,

I cloned the Magento GitHub repository git clone -b master git@github.com:magento/magento2.git

There's no error comes out when run " composer install ", everything's normal.

When run " magento setup:uninstall ", error occurs
Autoload error: A method by name getIterator already exists in this class.

The same problem: #1947

Please help me. Thanks.
Regards

You can try removing var/cache/*, var/generation/*, var/di/*, var/page_cache/* and trying to uninstall again.

You can also try cloning again into an empty directory and trying the install again.

[mazhalai]

@cfcnn can you please try @xcomSteveJohnson's suggestion and let us know if that helped?

[cfcnn]

Hi, @mazhalai @xcomSteveJohnson's suggestion is not working. I think I might find the solution, I need more time to test, I'll update later.

[cfcnn]

All tests were based on VMware 11, Centos 6.7 , nginx 1.8.0 & 1.9.0, php 5.5.25, 5.5.30,5.6.9, 5.6.14, mysql 5.6, mariadb 10.0.17, 10.0.21. No matter under what combination, it occurs the same error. All Magento2 installations failed even I kept changing the values of Centos, nginx, php.ini, my.cnf .

Magento 2 was installed successfully in production environment.

I have no idea what the problem exactly is. Maybe it's just a special case for me.

[orlangur]

@cfcnn, this problem does not seem to be env-specific.

Do you try clean Magento 2 installation or there are some additional modules? With latest develop, cleaned up var/* and database, executed composer install in advance does it show the same result now?

[orlangur]

Hmmm, very interesting, there is quite old similar issue also: #462 So, it could be something related to PHP Reflection behavior differences.

[cfcnn]

In order to keep all procedures pure, I reinstalled Centos, nginx, php, mysql,magento2.
Every magento2 installation was cloned by "git clone -b master git@github.com:magento/magento2.git" , it's supposed to be the latest version.
Before installation, the var/* directory is checked and confirmed clean,

The production environment : centos 6.4, nginx 1.8.0, php 5.6.14, mariadb 10.0.21.
I zip the magento2 installation file of test environment, upload it to production environment,
install it by "php magento setup:install --...", install successfully and work well at frontend and backend.
It is also installed successfully based on production environment of centos, apache, php, mysql.
No errors even reinstalling.
Same installation file is working fine in Win7 wamp.
http://prntscr.com/8r7xih

[orlangur]

I see. Don't know what else could be done here except debugging the code in action.

https://github.com/zendframework/zend-code/blob/3da502f243df7a189b9c1cfc70a96944ef111957/src/Generator/ClassGenerator.php#L751
So, with xdebug breakpoints or some additional temporary var_dumps needs to be tracked all $this-->methods property modifications during generation, to see, how the offsetUnset passes here for the first and second time. Only addMethod and addMethodFromGenerator methods do modify this property.

Hi @cfcnn .
Could you, please, provide your phpinfo()/php -i? Thanks.

[cfcnn]

https://mega.nz/#!rUJQnZoQ!5qLAaO_F8VG_MfVwpa0BPFWDZBNj9H0qL-dzSW9gUGQ

[buskamuza]

Thanks. Could you, please, try to disable opcache and see if it helps?

[cfcnn]

I disabled opcache before you told, it didn't help.
The file phpinfo.txt is what I used in both test environment and production environment.
Just now I test based on php 7.0.0RC4, in docroot, execute "composer install", error occurs:

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

Problem 1
- This package requires php ~5.5.0|~5.6.0 but your PHP version (7.0.0RC4) does not satisfy that requirement.

[mazhalai]

@cfcnn some package's composer's were not updated. We are working on it. Can you tell us which exact package gave this error?

[cfcnn]

@mazhalai My test environment: centos 6.7, nginx 1.8.0, php 7.0.0RC5, mariadb 10.0.21,
The latest developer version of Magento2 was installed, no error when installing in php 7.0.0RC5,
If install it in php 5.5,5.6, still has the same installation error:
