TypeError: Request path contains unescaped characters

Question

I try to install node.js modules using:

npm install express

but I get this error:

npm http GET https://registry.npmjs.org/e         


        

Answer 1

Set proxy from commandline.

npm config set proxy http://proxydomain:port/

If error occur yet, additional try next.

npm config set registry http://registry.npmjs.org/

These work for me. (ref http://sushichop.blogspot.jp/2013/01/npm-install.html)
