[Solved] Npm install hung or takes too long time

While working on Node you may be downloading various npm packages. Sometimes the download process just hung and does not move forward. You may also see errors related to non-reachable registry.npmjs.org URL.

Error

Typically error logs look like this:

E:\ngexamples\helloworld>npm install -g webpack
npm ERR! code ETIMEDOUT
npm ERR! errno ETIMEDOUT
npm ERR! network request to https://registry.npmjs.org/core-util-is/-/core-util-is-1.0.2.tgz failed, reason: connect ETIMEDOUT 104.18.95.96:443
npm ERR! network This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.
npm ERR! network
npm ERR! network If you are behind a proxy, please make sure that the
npm ERR! network 'proxy' config is set properly.  See: 'npm help config'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Lokesh\AppData\Roaming\npm-cache\_logs\2018-06-18T16_50_17_569Z-debug.log

Solution

Mostly (and for me as well) this error is due to incorrect proxy settings. Verify network proxy settings are correct.

Else try removing proxy settings using below commands and try again.

$ npm config rm proxy
$ npm config rm https-proxy

Hopefully above commands will sole this error for you as well.
