If in case you are using ubuntu trusty 14.0 then search for Network and select Network Proxy and make it none. Now proxy may still be set in system environment variables. check

env|grep -i proxy

you may get output as

http_proxy=http://192.168.X.X:8080/
ftp_proxy=ftp://192.168.X.X:8080/
socks_proxy=socks://192.168.X.X:8080/
https_proxy=https://192.168.X.X:8080/

unset these environment variable as:

unset(http_proxy)

and in this way unset all. Now run npm install ensuring user must have permission to make node_modules folder where you are installing module.

I also ran into the similar issue and was using CNTLM for proxy configuration  In my case HTTP PROXY and HTTPS PROXY are taking higher precedence over http proxy and https proxy so be aware of changing all proxy variables   env grep -i proxy   and make sure all of the below proxy variables should point to the same proxy   HTTP-PROXY    http   localhost 3128  HTTPS-PROXY    https   localhost 3128  HTTPS PROXY    http   localhost 3128  HTTP PROXY    http   localhost 3128  PROXY    http   localhost 3128  http-proxy    http   localhost 3128  http proxy    http   localhost 3128  https-proxy    https   localhost 3128   https proxy    https   localhost 3128  proxy    http   localhost 3128        I know some variables are unneccessary but I m not sure which is using what

Removing the proxy settings resolved the issue   If you are no using any proxy  npm config rm proxy npm config rm https-proxy  If you are using Proxy  npm config set proxy http   proxyhostname proxyport npm config set https-proxy https   proxyhostname proxyport  Hopefully this will solve your problem

After looking at all of the answers  the one that helped me was providing proxy values in-line with the install command  One of my frustrations was adding the domain to my username  This is not needed  I used the following example to install a specific version of Angular   npm install -g  angular cli 1 7 3 --proxy  http   username password proxy server proxy port  --registry http   registry npmjs org

An important point to remember is if you re behind a corporate firewall and you get you re corporate proxy settings from a  pac file  then be sure to use the value for global proxy

I know this is way too late but if someone has a similar issue in the future and you are sure you have no proxy set but you have an environment variable called http proxy  Please delete it and try again  I had set a proxy for Fiddler

Next to what has described  Roshith in his answer here   If you are behind a proxy  set it correctly in npm  npm config set proxy http   proxyhost proxyport npm config set https-proxy http   proxyhost proxyport   I had to change also the the file   bashrc which also contained a worng proxy setting in my case  I changed those settings here  export HTTP PROXY  quot http   proxyhost proxyport quot  export HTTPS PROXY  quot http   proxyhost proxyport quot   Use the following command to verify the proxy settings  env   grep -i proxy

If you using gnome  and turned off the proxy at the network level  you also need to make sure you don t have proxy enabled in your terminal    gconftool-2 -a  system http proxy    host   http   localhost   port   2000  use http proxy   false  use authentication   false  authentication password     authentication user     ignore hosts    localhost 127 0 0 0 8    You can drop it with  gconftool-2 -t string -s  system http proxy host    gconftool-2 -u  system http proxy port gconftool-2 -u  system http proxy host unset http proxy

If you are behind a proxy  set it correctly in npm    gt npm config set proxy http   proxyhost proxyport  gt npm config set https-proxy http   proxyhost proxyport   Notes    For SSL https proxies  the protocol in URL should be http not https If your set up is on a Docker Vagrant instance or a hosted VM  use IP address instead of hostname for proxy as the later might not be resolvable  If there is no proxy   remove proxy config from npm   gt npm config set proxy null  gt npm config set https-proxy null
