Node.js npm install express failed to fetch from registry [duplicate]

Question

I am starting my first Node.js server. I am attempting to follow a tutorial in Node.js.

Having installed Node.js and executed npm install, the next instruction is to start the server by running node server.js which generates the following error:

node.js:201
    throw e; // process.nextTick error, or 'error' event on first tick
          ^
Error: Cannot find module 'express'
    at Function._resolveFilename (module.js:332:11)
    at Function._load (module.js:279:25)

sisko@VirtualBox:~/Desktop/ExerciseFiles/01/03/start$

It seemed it needed a module called express so I looked around and found the npm install express command which should fix the issue. However, I get the following error:

sisko@VirtualBox:~/Desktop/ExerciseFiles/01/03/start$ npm install express

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

Seems like it's a SSL certificate issue with the repository, because it worked with HTTP but not HTTPS.

For troubleshooting only

To troubleshoot, on a sandbox where you're okay running untrusted code, you can confirm this by trying the repository under HTTP this insecure hack: running npm config set registry http://registry.npmjs.org/ (or whaterver repo) then npm install express. If that worked when the HTTPS doesn't, then it's probably an SSL issue.

Please do not use this insecure config as a fix. It's not a fix. Installing from HTTP opens you up to running code from a malicious source.

The fix is to update node/npm versions and/or fix the SSL.

This worked for me when I had the same problem installing a different package install, the clevertech-cli. It isn't just for express.

Could I know the reason why npm is configured, by default, with registry equals to registry.npmjs.org on debian and why it doesn't work for install package like express ? And it works for the same URL without ssl ?

worked for me as well to fix this error after installing npm package in ubuntu 12.04: "npm ERR! Error: failed to fetch from registry: canvas/1.0.4" ! Thank you

This seems to work, but is not a fix, IMHO. It allows a DNS poisoning attack to run arbitrary code as superuser. A workaround might be to install npm from source instead offrom Ubuntu 12.04 repository.

This helps as an alternative solution to accepted answer:

npm config set strict-ssl false

The problem with npm is that the default registry ssl certificate is not recognized properly.

Should be the answer...at least Mint or Ubuntu..it is working for me

rwwagner90 Over a year ago

Worked for me on OSX

SchizoDuckie Over a year ago

this turned out to be the solution for me too on raspbian. The proper solution will obviously be to fix the ssl cert tree
