  1. Delete package-lock.json file from your project, if it is created.

  2. Check your npm version using

     npm -v

  3. If your npm version is 5 and above. Then run the following command:

     npm cache verify

  4. Then run your install command

     npm install -g @ionic/cli

In case you are having the same issue.

I found a solution for this. Go to your terminal and run

npm cache clean --force or remove npm-cache folder manually from C:\Users\Admin\AppData\Roaming

And then run ionic start again
