Just in case your
tns plugin build command ever returns
"Error: The server returned unexpected response: "
you should try to append
--log=trace (in full command:
tns plugin build --log=trace) to find out what is going on.
In my case, I had a conflicting config in my
.npmrc file and the server configured in there returned a HTTP 401 .
.npmrc helped me to run my builds again. Finding it took 30mins of my evening...
Hope you found this earlier and that it helps you ;-)
