Exact issue on Ubuntu 12.04 when building msgpack:

Could be related to this: pgriess/node-msgpack#23

Not sure if the node-msgpack dependency just needs to be upgraded or the version in npm registry hasn't been updated.

Hmm. as a workaround, you could disable MessagePack, since it's optional unless you want to use that feature.

I'll try and test with the latest version.

[ddopson]

p.s, underscoreCLI lazy loads the 'msgpack' module, so if it's not installed, nothing will break unless you use that format directly.

[markphilpot]

Is there a way with npm to tell it to ignore the msgpack dependency?

[ddopson]

I wish that was "easier". By far the most straightforward way is to delete it from package.json

[ddopson]

I guess in theory, I could push a 2nd version of the module to the NPM repo ... "underscore-cli-nomsgpack" that would have exactly that package.json change. Is that worth it?

Here's some other folks asking for "optional dependencies" in npm:

!!!!! NPM supports a "optionalDependencies" field !!!!!!!!!

PROBLEM SOLVED. :)

pushing v0.2.16 that addresses this issue :)
