Nodemon tries to watch ignored folder -> error

[DABH]

• nodemon -v: 1.14.6 (just upgraded from 1.12.1)
• node -v: 8.2.1
• Operating system/terminal environment: Debian/bash
• Command you ran: nodemon --exec ./node_modules/.bin/ts-node -P foo --harmony --ignore bad-folder -- ./foo.ts

Expected behaviour

Runs without errors

Actual behaviour

Gives error: [nodemon] Internal watch failed: watch /home/bar/bad-folder EACCES

I have a folder bad-folder that only root can access (so, not nodemon). With previous nodemon, it would ignore this folder, no problem. Now, even though I pass the --ignore flag, nodemon still does some kind of watch on that folder, which causes nodemon to error out and stop. I also tried specifying to ignore this folder in nodemon.json and .nodemonignore but no matter what combinations of things I tried it seems nodemon always wants to put an internal watch on that folder, which will fail. Any ideas if this is something I'm doing wrong, or a new bug? (I've never had this issue before 1.14.6.) Thanks!

Can you re-run with the addition of -V (verbose) and include the full output here? I'm specifically looking for what nodemon says it's ignoring:

nodemon -V --exec ./node_modules/.bin/ts-node -P foo --harmony --ignore bad-folder -- ./foo.ts

In fact, can you also run the command with the --dump param and include the config info. It might reveal something different in the config to help debug (I tried to replicate locally quickly, but it didn't work - I suspect there's something slightly different that I missing).

Thanks for taking a look! Think I got a fix but fwiw here's the complete info:

As you can see from the log, by passing --ignore bad-folder, it was actually ignoring bad-folder/**. However, if I pass --ignore **/bad-folder, it ignores what I want and there's no error.

However, in v1.12.1, the original ignore list looks the same with the dump (i.e., bad-folder/**), and it works fine. So, maybe this isn't a full-out bug since there's an easy workaround, but at the least this seems like a difference in behavior between the two versions. Happy to provide more info if helpful, thanks again!

(Also, it shouldn't matter, but here are the permissions that stat reports on bad-folder, just in case):
Access: (0700/drwx------) Uid: ( 999/ UNKNOWN) Gid: ( 0/ root)

I think I've fixed this. You can test it out before it's released via npm install nodemon@debug.

It should work with nodemon --exec ./node_modules/.bin/ts-node -P foo --harmony --ignore bad-folder -- ./foo.ts - let me know how it goes (I'll likely release either tomorrow or Monday).

[DABH]

Works for me now! Thanks very much for the fix, cheers!
