问题
Hello everyone I´ve been trying to configure and use npm on my enterprise PC without success.
I´ve set proxy, https-proxy, strict-ssl false, registry http://registry.npmjs.org proxy has been set like this "http://user:password@proxy_ip:proxy:port" Where the password has a special character written in urlencode.
npm config get proxy
returns proxy with credentials as they should be.
I have cleared my npm cache and tried again.
No success.
Any ideas what can be the problem?
回答1:
Usually, when you are behind a corporate proxy, it is needed to add the domain where you are at. Given that also the characters should be URL encoded, it would look like:
https://domain%5Cusername:password@proxy:port

We should add proxy with username and password to avoid this error For example : username - admin, password - admin123, proxy - 172.10.3.21, port - 3128
npm config set proxy http://admin:admin123@172.10.3.21:3128 npm config set https-proxy http://admin:admin123@172.10.3.21:3128

I recommend reading through this article to configure the proxy for npm. http://wil.boayue.com/blog/2013/06/14/using-npm-behind-a-proxy/
npm config set proxy http://proxy.company.com:proxyportnpm config set http-proxy http://proxy.company.com:proxyportnpm config set https-proxy http://proxy.company.com:proxyport
Hope this is useful for you!

Editing the .npmrc file in user folder worked for me. I set the proxy and npm registry as follows:
proxy=http://username:password@proxy:port/
https-proxy=http://username:password@proxy:port
registry=http://registry.npmjs.org/
Note : for usenames and passwords containing special charcters, the characters need to be encoded in the proxy configuration. e.g if username is "user" and password is "1234@user", then the .npmrc file will look like :
proxy=http://user:1234%40user@proxy:port/
https-proxy=http://user:1234@user@proxy:port
registry=http://registry.npmjs.org/
where, %40 is the encoded form of "@". In my case, the pound symbol(#) was not getting accepted in username or password(Dont know why).
