Create new app ionic angular

When I try to create new Ionic app ( ionic start myApp tabs ) with Angular I get this error

npm ERR! Unexpected end of JSON input while parsing near '...74dbd","tarball":"htt'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\admin\AppData\Roaming\npm-cache\_logs\2020-10-30T15_03_33_476Z-debug.log
[ERROR] An error occurred while running subprocess npm.

But when I try to create ionic app with React all is good.
What am I doing wrong?

os - windows 10
node - v14.15.0
ionic-cli - 6.12.1
Angular CLI: 10.2.0

Welcome to the Ionic Forums.

The most important thing here: your error message suggests to me a corrupted download. I would clear npm’s cache, or if you are using a version manager such as nvm (highly recommended), you may even want to consider cleaning the entire node installation.

Some additional context:

Sometimes the terminology surrounding the various versions of things in Ionic-land can be confusing. When creating a new project, ionic-angular refers to an old version of Ionic Framework (v3) that is only receiving maintenance updates. I would not recommend using it for new projects. I would instead recommend generating a type “angular” project, which is the most recent and active version of Ionic Framework.
