When I run “ionic prepare ios” I get the following message: Error: EPERM: operation not permitted, open ‘D:\dev\blue\_mobile\_app\platforms\ios\Blue Service.xcodeproj\project.pbxproj’ Because of that I have to remove and add ios platform again. It happens even with admin permissions. Any ideas of whats wrong? ordova CLI: 6.5.0 Ionic Framework Version: 3.0.1 Ionic CLI Version: 2.2.3 Ionic App Lib Version: 2.2.1 Ionic App Scripts Version: 1.3.0 ios-deploy version: Not installed ios-sim version: Not installed OS: Windows 10 Node Version: v6.10.0 Xcode version: Not installed ---

Virus scan? Any other program running that could block a file? Did you restart your computer? ---

It seems to be working after I ran “npm install” again. Not sure what was wrong!
