vue-cli · tunneling socket could not be established, cause=socket hang up

when i used vue init webpack demo
it reported this error : " vue-cli · tunneling socket could not be established, cause=socket hang up"

I am still having this problem. I’m using

windows7, vue-cli@2.8.2, npm@5.3.0 and node@8.2.1.

I am behind a corporate proxy and I am able to use npm and git through the proxy. My system environment variables are set as follows

HTTP_PROXY = “http://{IP address}:{port}/” HTTPS_PROXY = “https://{IP address}:{port}/”

The proxy IP and port number in my system environment match the proxy settings I have in my npm config which I verify from the command line with npm config -g list and reading both proxy="http://{IP Address}:{Port}/ and https-proxy="https://{IP Address}:{Port}/". And yet when I command

vue init webpack vue-xperiment

I receive the error

vue-cli · Failed to download repo vuejs-templates/simple: tunneling socket could not be established, cause=socket hang up

How can I check directly from the command line which proxy settings the vue-cli is trying to use? Because either it isn’t reading from the system environment vars, or else something else is blocking the connection.

For me, I had to make sure the HTTPS_PROXY variable was set. I did it in ~/.zshrc but you could declare it in ~/.bashrc and then source it, or export it system-wide as well and then open a new terminal window.
