In a case that looks similar to this problem, I have installed a module with npm, but
require('module') can't find it.
my-machine:projectname me$ npm install express-csrf npm info it worked if it ends with ok npm info version 0.2.1 npm info install email@example.com npm info activate firstname.lastname@example.org npm info build Success: email@example.com npm ok
So far, so good. But then...
my-machine:projectname me$ node > require('express-csrf') Error: Cannot find module 'express-csrf' at Function._resolveFilename (module.js:317:11) at Function._load (module.js:262:25) at require (module.js:346:19) at [object Context]:1:1 at Interface.<anonymous> (repl.js:171:22) at Interface.emit (events.js:64:17) at Interface._onLine (readline.js:153:10) at Interface._line (readline.js:408:8) at Interface._ttyWrite (readline.js:585:14) at ReadStream.<anonymous> (readline.js:73:12)
npm says the package is there:
my-machine:projectname me$ npm ls express-csrf npm info it worked if it ends with ok npm info version 0.2.1 firstname.lastname@example.org active installed npm ok
Note that the new module doesn't appear in the /usr/local/lib/node directory, but it does appear under /usr/local/lib/node/.npm
my-machine:projectname me$ ls /usr/local/lib/node/express-csrf* ls: /usr/local/lib/node/express-csrf*: No such file or directory my-machine:projectname me$ ls /usr/local/lib/node/.npm/express-csrf* 0.3.3 active
Update: I should mention that everything works when I fully qualify the path in the
require statements like so:
Your problem is that require() doesn't search the .npm folder.
You can solve this by upgrading npm so that it places files in the right spots. Alternatively, you can install your modules manually in a folder in the root of your project and require('../mymodule')
