Bower calls blocked by corporate proxy and then I get errors when updating .bowerrc
Try adding the following property that I found on this old github thread
{ "directory": "app/bower_components", "registry": "http://bower.herokuapp.com", "proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/", "https-proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/", "strict-ssl": false}
