I want to install Nodemon on my ubuntu, but I get an error and I could not.

#npm install -g nodemon

It looks like it installed correctly.

The only error is a warning:

npm WARN optional dep failed, continuing fsevents@1.0.12

Please note that fsevents is only for supporting OS X hosts (https://github.com/strongloop/fsevents) and is not needed on Linux/Ubuntu.

You should be able to run the nodemon command in your terminal to verify this.
