Description

Hi I tried your generator today and I had the error below when running gulp serve or gulp test :

Environment

(it is strange node says I'm on win32 but I'm on a Windows 10 64 bits plateform an use an node x64 version).

> node -e "var os=require('os');console.log('Node.js ' + process.version + '\n' + os.platform() + ' '
+ os.release())"
Node.js v6.11.4
win32 10.0.15063

> yo --version
2.0.0

> npm --version
3.10.10

Solution

I had to lower my TypeScript version from 2.5.3 to 2.3.4 as suggested here : angular/angular#17800

I didn't tried other versions of TypeScript or tested the whole project with this version, but gulp serve works for me.

Romain.
