My proxy settings (fiddler proxy for testing purposes):
.nmrpc
proxy=http://localhost:8888/
proxy-https=http://localhost:8888
strict-ssl=false

I've already tried to set environment variable: HTTP_PROXY to match configuration used in .npmrc without any results.

I had the same problem, but I managed to install the packages by executing these commands before executing the npm install:

set HTTP_PROXY=http://proxy:port
set HTTPS_PROXY=http://proxy:port
set STRICT_SSL=false

Of course, this only works temporarily in the current command session. But setting it as an environment variable requires you to set those on every system where you want to build. A better solution might be to have a script that sets the variables before calling npm install.

I've got the same error, but neither solution worked.

Is it possible to update the downloader to use the proxy / https-proxy settings of NPM rather than the system settings? This is particularly annoying when trying to build using the frontend-maven-plugin which passes the relevant Maven proxy settings through to NPM but the only way I was able to get this to work is to additionally set the http_proxy and https_proxy environment variables.
