Permission denied error when I run ionic build ios command?

Question

When I ran

ionic build ios

I get the following error.

sh: /Users/imac/Documents/TGF_IOS/node_modules/.bin/ionic-app-scripts: Permission denied

Any help will be appreciated.. Thanks in advance

Finally i have got the solution.

First step check if you have permission (read/write) to the project folder.

Secondly, run this command with sudo,

sudo npm install @ionic/app-scripts@latest --save-dev

This will install latest app-script and wll fix the issue.
