yii2-bootstrap | Yii 2 Bootstrap 3 Extension | Web Framework library

Just try to import your fonts in simple template file, if it's working fine, the problem will be with your path aliases. (I mean for example with @web or in your case with @webroot)

Or you can use Application Assets, you can write your own and you can define all dependencies what you want to use for the application. Also there are some examples with aliases and you can try out what will be happen if you use them like there.

As far as I can see in the repository for fxp/composer-asset-plugin, it has seen some updates for the property $verbose which is no longer available in current Composer versions. You should update that package.

As it is not listed in your composer.json, some other package seems to require it. And to update the asset plugin, you probably need to update that other package too - check through composer why fxp/composer-asset-plugin which other plugin is responsible for this

You need to remove the previous entry of the "yiisoft/yii2-bootstrap" from your composer.json before installing the yiisoft/yii2-bootstrap4, its pretty straight forward

• remove the previous version
• run composer update
• add the new one yiisoft/yii2-bootstrap4:"~1.0.0"
• run composer update

after that change the namespace to the new class in your assets class $depends array and that is it.

You can also remove the associated folder manually or delete the whole vendor folder, and then run composer update

Update

Above all the main problem wasnt addressed which was labelled as Problem 1 in the OP's added exception message. Sorry about that.

You should also change the version of the yii2-soap-client to dev-master from * as the error says

Installation request for mongosoft/yii2-soap-client (locked at dev-master, required as *) -> satisfiable by mongosoft/yii2-soap-client[dev-master].

so change the

Most of widgets in default views of yii2 projects use yii\bootstrap\BootstrapAsset (bootstrap 3). Do not expect it magically toggle when you call yii\bootstrap4\BootstrapAsset.

Your step 2.3 is just adds bootstrap 4 to all other libraries you call by using widgets.

What you can do:

1) make sure you are calling yii\bootstrap4\ widgets and not calling yii\bootstrap\BootstrapAsset or any assets that depends on this class. Examples:

• use yii\bootstrap4\Html;
• use yii\bootstrap4\Modal;
• use yii\bootstrap4\Tabs;
• use yii\bootstrap4\ActiveForm;

2) Remember that bootstrap 4 have different classes than bootstrap 3. So if you will apply it to default views it highly likely will break because it does not have some classes from other version, or js acting differently.

You've got there "kartik-v/yii2-date-range": "dev-master" which means that you ask for latest dev version of the package which is not preferred but you can still get this if you change "kartik-v/yii2-krajee-base": "~1.7" to "kartik-v/yii2-krajee-base": "^2.0" because right now you are blocking it (and this is exactly what the composer information states). Read more about composer version constraints.

I'm not sure what was the reason why it stopped working for you but as we discussed in comments the solution was to update the entry in auth.json that stores this GitHub token.

For everyone looking for this solution - auth.json is stored in your COMPOSER_HOME path. You can find this path by calling in the console

Basically the composer update was not generated the extension.php properly. There was the alias issue which worked after delet the vendor folder on server and update the composer again.

You need to change your project name. According to your composer.json your project is yiisoft/yii2, which is not true. I have no idea how did you get this composer.json, here is the official template - your app structure and composer.json should look similar (alternatively you may try advanced template). After changing package name, this command should do the trick:
