Getting Uncaught Error Assertion Failed Ember Views Require Jquery Between 1 7 And 2 1 With App Created Through Ember Cli

When working with Ember.js, encountering errors is a common part of the development process. One such error that many developers come across is the "Assertion Failed: Ember Views require jQuery between 1.7 and 2.1" error. This error typically occurs when you are using an Ember application that was created through Ember CLI and there are compatibility issues with the version of jQuery being used.

To resolve this error, you will need to ensure that the version of jQuery being used in your Ember application falls within the specified range of 1.7 to 2.1. Here's a step-by-step guide to help you fix this error:

1. Check Your jQuery Version:
The first thing you need to do is verify the version of jQuery that your Ember application is currently using. You can do this by looking at the dependencies in your project's package.json file or by checking the version specified in your project's bower.json file.

2. Update jQuery Version:
If the version of jQuery in your project is outside the range of 1.7 to 2.1, you will need to update it to a version that falls within this range. You can do this by running the following command in your project directory:

npm install --save-dev jquery@1.11.1

This command will install jQuery version 1.11.1, which is a version that is compatible with Ember Views.

3. Update Your Ember Application:
After updating the jQuery version in your project, you will need to update your Ember application to ensure that it is using the newly installed version of jQuery. You can do this by restarting your Ember server and rebuilding your application:

ember serve

This command will restart your Ember server, and your application will now be using the correct version of jQuery.

4. Test Your Application:
Once you have updated the jQuery version and restarted your Ember server, it's essential to test your application to ensure that the error has been resolved. Check if the Assertion Failed error no longer appears, and make sure that your application functions correctly.

By following these steps, you should be able to resolve the "Assertion Failed: Ember Views require jQuery between 1.7 and 2.1" error in your Ember application created through Ember CLI. Remember to always keep your dependencies up to date and ensure compatibility between different libraries and frameworks in your project. Fixing errors like this will help you create smoother, more robust applications with Ember.js.
