NPM does not install anything : it hangs

问题:

Whenever I want to install a module with NPM, it hangs at that stage:

npm install express
npm http GET https://registry.npmjs.org/express

And that's it. It has that behavior for anything I input instead of express. I installed nodejs and nvm that way (Ubuntu 13.10):

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

I tried looking on the Internet and GitHub and I found a closed issue about npm hanging forever when trying to install a module.. but it was a really old issue. Before I ask the developers, am I missing something obvious ?

I tried compiling both nodejs and npm but the result was the same.

EDIT: npm install express -verbose -> http://pastebin.com/tGY3V6Ly Error:

npm info retry will retry, error on last attempt: Error: tunneling socket could not be established, cause=140072708810560:error:140770FC:SSL   routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:766:

NPM has been having server issues of late. Try running the command with -verbose to check and see what is going on, and be patient.

I had this issue on a BeagleBone Black (low power ARM device) and running npm cache clean seemed to get things moving again.

Try without https:

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

回答4:

After an hour of struggling, I cleaned .npm and node_modesl/.staging directories, and problem just gone! (replace the paths with your own)

yes|rm /root/.npm/* -R
yes|rm /path/to/node_modules/.staging/* -R
npm install

I had the same issue and I solved by disabling all my firewalls

回答6:

I opened console with admin privileges and the ran npm install on windows. My problem was fixed with this

回答7:

I had the same error and the problem was in proxy: previously I set up HTTP_PROXY environment variable and after removing it npm install completed without any error.

回答8:

I had this problem inside a Windows git bash terminal - reinstalling the latest version of git bash fixed it

回答9:

I was using an older version of node. I used a newer version Type in Terminal:

nvm use stable

and then

npm i

and all worked just fine.
