Error: Cannot Find Module 'winston' (Forever 0.5.1 and winston 0.2.7) about forever

[indexzero]

What version of npm are you using? winston is in the package.json file. Can you try:

npm ls forever

And see what the output is?

Hi, thanks for the follow up.

Using npm version 1.0.6 and below is the output from "npm ls forever"

root@chat-burako:# npm ls forever
npm WARN ls doesn't take positional args. Try the 'search' command

My stack trace when trying to run forever:

throw e; // process.nextTick error, or 'error' event on first tick

Ok, can you try this?

npm uninstall forever -g 
npm uninstall forever
npm install forever -g

See if that helps? Winston is clearly installed under your /root directory below forever as shown in your output from npm ls forever, but npm is trying to load forever from /usr/local/sbin/forever as shown by your stack trace.

Have you recently upgraded npm to 1.0?

If I clone from GIT and go to the ~/forever/bin , and run ./forever, I get the same error and the stack shows it's loading from /root directory

I tried the uninstall/install sequence you gave me and still get the same error. I'm not sure if I upgraded recently or not. Do you think I could try reinstalling npm?

[indexzero]

Getting that error is expected if you clone from git and cd to that directory because npm has not yet installed any of the dependencies. Try this:

  mkdir /root/somefolder
  cd /root/somefolder
  git clone [email protected]:indexzero/forever.git
  cd forever
  npm install .
  ./bin/forever list

Do you still get the error after running that command sequence?

[indexzero]

Also, I still need to know: Have you been using npm long? Did you recently upgrade from 0.3.18 to 1.0.6? npm changed significantly for 1.0 and you should be aware of how it works:

@indexzero, the method to reinstall forever and run it from ./bin worked, the error no longer appears. What do you suggest, to copy the forever executable to /usr/local/sbin (and how/where would I need to copy the dependencies) or to PATH the git forever clone on my box, in order to use forever from any path in the command line?

The npm I've been using just for a couple of weeks, when I discovered socket.io and node.js when researching to develop my chat server. I don't think I went as far back as 0.3.18.

Thanks

Have you tried reinstalling node / npm?
