Having trouble launching simple ionic template: Issue with locating module 'fast-deep-equal'

Recently I started using Ionic and followed the steps to install the basic blank template as shown below.

First, I installed Ionic and Cordova by running the command:

npm install -g ionic Cordova.

After that, I created my first Ionic project using the following command:

ionic start myApp1 blank

Then, I navigated into the myApp1 directory and attempted to run the application with this command:

ionic serve

However, I encountered the error mentioned below:

ionic serve
Error: Cannot find module 'fast-deep-equal'
at Function.Module._resolveFilename (module.js:513:15)
at Function.Module._load (module.js:463:25)
at Module.require (module.js:556:17)
at require (internal/module.js:11:18)
at Object.<anonymous> 
(D:\Proj\myApp1\node_modules\ajv\lib\compile\resolve.js:4:13)
at Module._compile (module.js:612:30)

at Module.load (module.js:531:32)
at tryModuleLoad (module.js:494:12)
at Function.Module._load (module.js:486:3)

I attempted to resolve the issue by deleting the node_modules folder, removing the package-lock.json, and re-installing everything using the npm install command, but unfortunately, the problem persists.

The version of Ionic I am using is 3.19.1 and the node version is 5.4.2

If anyone has any suggestions on how to fix this issue, please let me know. Thank you!

Answer №1

This issue occurs when your project is unable to locate the 'fast-deep-equal' module. To resolve this, you need to install it by following these steps:

Navigate to your project directory and run the following command:

npm install fast-deep-equal

If an error persists, try deleting all content within node_modules.bin\ and running the installation command again.

I hope this solution helps you resolve the problem as it did for me.
