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
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 18.104.22.168:443 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
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.
Happy Learning !!
