I am on Linux Debian I had this error a few times I tried to install uninstall with npm install and npm uninstall

ionic -v
2.1.14

> ionic-app-scripts serve

[11:15:49]  ionic-app-scripts 0.0.47 
[11:15:49]  watch started ... 
[11:15:49]  build dev started ... 
[11:15:49]  clean started ... 
[11:15:49]  clean finished in 3 ms 
[11:15:49]  copy started ...

[11:15:51]  build dev failed: Cannot set property 'fileSystem' of null 
[11:15:51]  dev server running: http://localhost:8100/

  • If you have installed latest ionic cli.. get ionic-app-scripts 1.0.0..check the answer – Suraj Rao Feb 04 '17 at 10:55
  • "*I installed `ionic-app-scripts 0.0.47` like I read in the others answers*" - that is not what the answers said. Where did you read that? – melpomene Feb 04 '17 at 10:56
  • npm install @ionic/app-scripts@latest give me this error `@ionic/app-scripts@1.0.0 invalid` – Leonel Feb 04 '17 at 11:03
  • change the version of app scripts in your package.json then delete node-modules and then do npm install – Suraj Rao Feb 04 '17 at 11:10
  • check the other answer for package.json – Suraj Rao Feb 04 '17 at 11:10

Install this : "@ionic/app-scripts": "1.0.0" version of app-scripts in your package.json.

This error came after npm update or ionic lib update (I wanted to test these commands... BIG MISTAKE).

Be careful with lib update.
