Error installing @ionic/app-scripts in visual studio 2017

Ionic Framework
1

HI I have been looking through the forums and I have found people with similar errors but I am having trouble fixing mine. When I try install the dependencies after starting a new project they all install except for @ionic/app-scripts.

this is my error log
Build failed with error code: 1

Is it possible that the proble is due to node-sass because cmd and visual studios say that they are 2 different versions

9

npm uninstall npm -g

npm i npm@3.10.10 -g

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

Then try to run the initial command that led you to the error.

That didnt work still saying @ionic/app-scripts not installed

I didnt get errors in the console running thos commands. But in vs when i try install dependencies I still have the same problem
