Npm install fails after git clean

I’ve been working on a new project and now, after initially checking it into git, I did a git clean to make sure that someone else would be able to checkout and get all the files.
Problem is, when I run npm install I get an error related to node-sass

C:\Users\usecarkm\Source\Repos\ui\IonicPages>npm install
npm WARN prefer global node-gyp@3.6.0 should be installed with -g

> node-sass@4.5.0 install C:\Users\usecarkm\Source\Repos\ui\IonicPages\node_modules\node-sass
> node scripts/install.js

My ionic info:

global packages:

    @ionic/cli-utils : 1.5.0
    Cordova CLI      : 6.5.0
    Ionic CLI        : 3.5.0

local packages:

    @ionic/app-scripts              :
    @ionic/cli-plugin-cordova       : 1.4.1
    @ionic/cli-plugin-ionic-angular : 1.3.2
    Cordova Platforms               : none
    Ionic Framework                 : ionic-angular


    Node       : v6.10.2
    OS         : Windows 10
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed
    npm        : 5.0.3

Did I clean up something I shouldn’t have?

I’ve just noticed someone else with what appears to be the same issue, here:
Can not start new project on ionic 1 … but as yet unanswered.

This is strange. There should only be version numbers - and app-scripts 1.3.0 causes these issues with npm5.

Please post your packages.json content so we can fix this.

Based on a lot of other posts recently, I realized that there’s problems with npm v5. I uninstalled nodejs (completely:, then reinstalled v6.11.1 which contains npm v3.10.10, and this fixes the error I was getting.

I saw your post just after mine. In case it’s still relevant, here’s my package.json contents:

Ok, something in your npm got really strange packages.

For npm5 to work (5.03 and 5.1.0 work just fine now) with Ionic you need a newer app-scripts - best 1.3.12 or even a 2.x (but read the changelog for this).
