dep hung for a minute until I interrupted

[watilde]

Summary

on the second last run, dep hung for a minute until I interrupted it, but the other two runs it installed in a dozen or so seconds. https://github.com/watilde/dep/issues/7

Steps to reproduce behavior

$ dep i; ls -l node_modules/eslint/bin/eslint.js                                                                                        
Resolving dependencies
Installing dependencies
^C

Expected behavior

It shouldn't be hung.

Actual behavior

It's hung for a minute.

On https://github.com/strongloop/strong-deploy

sn/strong-deploy (master u=) % dep i
Resolving dependencies
Installing dependencies
Installed 808 packages in 46.812s

This says it took 46 seconds, but I think it took much longer, I'd been waiting, then went to have
a conversation, and it was done when I came back. So, I tried again, because I think the timing info
might be wrong.

sn/strong-deploy (master u=) % git clean -x -d
Removing node_modules/
sn/strong-deploy (master u=) % time dep i     
Resolving dependencies
^C
dep i  5.76s user 0.70s system 1% cpu 6:32.58 total

Over 6 minutes, but no install.

This is on 16.04 ubuntu, x64, fwiw.

I'm running again, to see if its deterministic.

sn/strong-deploy (master u=) % time dep i     
Resolving dependencies
^C
dep i  6.38s user 0.69s system 1% cpu 5:56.61 total

Seems to happen each time.

Oops, I actually could install the deps in 20s.

click here

$ git clone https://github.com/strongloop/strong-deploy.git
$ cd strong-deploy
$ dep i
Resolving dependencies
Installing dependencies
Installed 901 packages in 20.094s

With npm without cache, it took almost same time:

click here

$ npm cache clean -f
npm WARN using --force I sure hope you know what you are doing.

$ npm i
npm WARN deprecated node-uuid@1.4.8: Use uuid module instead
npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated nodemailer@2.7.2: All versions below 4.0.1 of Nodemailer are deprecated. See https://nodemailer.com/status/
npm WARN deprecated connect@2.30.2: connect 2.x series is deprecated
added 544 packages in 23.391s

I will try again to figure out the problem anyway.

If you have suggestions on diagnostics I can run, I would happily do it.
