Cannot find module 'log4js'

[hopewise]

After npm install, I tried to run the producer, I got this error:

Error: Cannot find module 'log4js'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)

So, what's wrong?

try "npm install log4js" separately. Your package.json might be missing the dependency.
