npm install error/issue

Question

I have already set proxy configurations in .npmrc file. Executing the npm install command gives me error as follows\"

$ npm install npm ERR! Windows_

Answer 1

first give the command and check if proxy is set,npm config get proxy if not set do the following from command prompt

npm config set proxy http://username:password@proxy address:8080 npm config set https-proxy http://username:password@proxy address:8080

and if password contains '@'in password, then replace it with '%40'

Answer 2

Someone who comes from china may solve this problem by using Taobao mirror.

npm --registry=https://registry.npm.taobao.org install

Answer 3

Does your proxy URL have '@' symbol in it? @ symbol separates the user ID and password from the URL. If it does, you can try using '%40' to replace it.

Also, it is https-proxy not http_proxy.

A correct config would look like -

registry=https://registry.npmjs.org/
proxy=http://username:password@proxydomain:8080/
https-proxy=https://username:password@proxydomain:8080/
