Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead

Question

I just freshly installed Node.js and now I'm trying to run a simple script, but I get the following error message:

Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead.
    at Function.<anonymous> (module.js:383:11)
    at Object.<anonymous> (/home/shawn/.node_libraries/[email protected]/index.js:4:21)

    at Object.<anonymous> (/home/shawn/Documents/Projets/jsonpExchange/server.js:1:77)
    at Module._compile (module.js:446:26)

What does it mean, and how can I solve it?

UPDATE:

$ node -v

v0.6.19

$ npm install express

Answer 1

This error happens when some installed packages are built for an older version of nodejs.

Which version of node are you using?

$ node -v

Are you using npm (http://npmjs.org) to install packages? The output of install express should be like this:

$ npm install express
npm http GET https://registry.npmjs.org/express
npm http 200 https://registry.npmjs.org/express
npm http GET https://registry.npmjs.org/mime/1.2.4
npm http GET https://registry.npmjs.org/mkdirp/0.3.0

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