'Ion-text' is not a known element

Ionic Framework ionic-v3
1

Hi All,
I am trying to use ion-item example as given in https://ionicframework.com/docs/api/item

                <ion-label text-wrap>
                    <ion-text color="primary">
                        <h3>H3 Primary Title</h3>
                    </ion-text>
                    <p>Paragraph line 1</p>
                    <ion-text color="secondary">
                        <p>Paragraph line 2 secondary</p>
                    </ion-text>

But it says -

'ion-text' is not a known element:
1. If 'ion-text' is an Angular component, then verify that it is part of this module.
2. If 'ion-text' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("
                <ion-label text-wrap>

                    [ERROR ->]<ion-text color="primary">

                        <h3>H3 Primary Title</h3>
"): ng:///AppModule/Dashboard.html@58:20

Hi @rahjain

I think ion-text component is only available on Ionic 4 projects.
You are using version 3.x.

Thanks @irvingprog for this information.
I am very new to ionic.
Is it good to upgrade ionic from 3.x to 4 ?

@rahjain

If you are just starting a new project and learning i recommend using Ionic 4.

If your maintaining a project that was made using Ionic 3.x you should see how much customized is and research what things of those are not too easy to do with Ionic 4 that were with ionic 3.x, in order to have a perspective about upgrading.
