do you have a stack trace of the error? and more info about your config? seems you are just missing the configuration of that component.

[mehdi1564]

no , have not a stack trace.

my yii1 config:

no idea why it is not there by default but you may add the i18n component config like this one to the yii2 config: https://github.com/yiisoft/yii2/blob/master/framework/base/Application.php#L622

[mehdi1564]

tnx, but not work still, generally how do I upgrade my version 1 to version 2? Should I start coding?

[cebe]

upgrading from 1.1 to 2.0 genearally needs a rewrite of your code.

[CreateWithCoding]

this solved for me here by making sure you are using Require like below throughout your index.php under /web

Reference here: https://stackoverflow.com/questions/33496841/yii2-error-the-id-configuration-for-the-application-is-required

Here's your problem:

$config = (DIR.'/../config/web.php'); $config contains the path to web.php, not its contents. It should be:

$config = require(DIR . '/../config/web.php');
