When I install ionic I get the following error:

npm ERR! code EPROTO npm ERR! errno EPROTO npm ERR! request to https://registry.npmjs.org/async-limiter/-/async-limiter-1.0.0.tgz failed, reason: write EPROTO 0:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:827: npm ERR!

I'm using windows 10 in a network whose server runs Ubuntu-16. I'm behind a proxy and set the parameters as below:

$ npm config set proxy http://<username>:<password>@<proxy-server-url>:<port>
$ npm config set https-proxy http://<username>:<password>@<proxy-server-url>:<port>

It should be http-proxy- instead of just proxy.

npm config set http-proxy http://<username>:<password>@<proxy-server-url>:<port>
npm config set https-proxy http://<username>:<password>@<proxy-server-url>:<port>
