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

Though late enough, I've bumped into this too after updating nodejs (to 4.1.1) and npm (to something like 1.4.x) on Linux.

I've tried the suggested solution, but changing the registry entry did not help in all cases. Lastly, having decided to reinstall npm, I found this update source [on npm github][1]

curl -L https://www.npmjs.org/install.sh | sh

which updated my npm to 3.3.8 and all related package installation troubles have been blown away.

Answer 2

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)
