hi postables,

wich version of node js and npm do you use

[bonedaddy]

Node: v8.11.2
NPM: 5.6.0

[josselinchevalay]

try that : https://stackoverflow.com/questions/46703864/receiving-npm-err-unexpected-string-in-json-at-position-20938-within-an-ionic-3 if works that can serve to workaround pending reach why.

so rm package-lock.json and run npm install --only-dev

regards

[josselinchevalay]

ok package-lock seems corrupted i will change that

[bonedaddy]

So far your rm package-lock.json is working and it's currently installing.
