Magento – Something went wrong while installing sample data. Please check var/log/system.log for details during Magento installation

magento2PHP

I am a beginner in Magento. When i was trying to install "Magento-CE-2.0.0+Samples-2015-11-17-06-11-18.zip" on my local server using Wamp,it first gets stuck at 90%, after quite a while, it shows "Success" but at the end of the page it shows the following error-

"Something went wrong while installing sample data. Please check
var/log/system.log for details. You can retry installing the data now
or just start using Magento"

I checked the "var/log/system.log" and there is this message-

[2015-12-21 09:42:48] main.ERROR: Sample Data error: Warning:
IntlDateFormatter::parse(): Date parsing failed in
C:\wamp\www\Magento\vendor\magento\framework\Stdlib\DateTime\Timezone.php
on line 166 [] []

when i click at the button "Launch Magento Admin" which is situated at the bottom of the page, i get this error

What can i do to solve this problem?

I have already posted it on "Stack Overflow" because i didn't know this forum exists. There is no answer on "Stack Overflow" so i have posted it here again.

I could not find a solution for date parsing issue yet. But as per sample data installing you can try below commands from your installation directory.

php bin/magento sampledata:deploy
php bin/magento setup:upgrade

then compile if required

php bin/magento setup:di:compile

Magento 2 Installation – Errors Installing Sample Data: Class Not Found

Did you download version 1.0.0-beta from the releases page (or master branch), or off of the current develop branch?

My understanding is that the develop branch is not stable/sample data won't work, but it should be fine if you're using the official beta1 release. You can find that here: https://github.com/magento/magento2/releases

Magento – Magento2 : Something went wrong while saving the rule data. Please review the error log

A good trick is to search the GitHub repository for Magento 2 for the error strings which will lead you to the classes - this error string appears in two classes. One related to catalog rules and another related to quote - which I would guess would be what we're looking for).

The error is being generated by a catch all Exception block inside this class:

magento2/app/code/Magento/SalesRule/Controller/Adminhtml/Promo/Quote/Save.php

(or /vendor/magento/module-sales-rule/Controller/Adminhtml/Promo/Quote/Save.php)

Line ~102 depending on version:

       } catch (\Exception $e) {

            $this->messageManager->addError(

                __('Something went wrong while saving the rule data. Please review the error log.')

            );

I know it's forbidden to play with core, but sometimes these things get a bit annoying - and the update should be temporary only for debugging purposes, unless you need to provide a proper error message to an external system, in which case you'd probably override the method. if you're not on a production server you could try to back up the above file, then add an $e->getMessage() to the error output so you can immediately know why this is failing.

(Since you're a beginner - I would suggest checking the log file and reporting back to us instead of doing this)

} catch (\Exception $e) {

    $this->messageManager->addError(

                __('Something went wrong while saving the rule data. Please review the error log. ERROR: %1', $e->getMessage())

);
