[22:55:05] <organicHack> Hey all.  Got a Q about deployment best
practices.  I have a working app with Polymer locally, but when I go to
deploy (fresh npm install, fresh bower install) I get issues like:
ECONFLICT Unable to find suitable version for polymer
[22:55:19] <organicHack> I have a "resolutions" block in my bower.json
[22:55:30] <organicHack> but im a little unsure about the best practice
for that.
[22:57:27] <organicHack> ive noticed as well that i have issues updating
locally, works better to just blow away dependencies and install fresh.
[22:57:28] <organicHack> related
...
[23:20:01] <organicHack> When i do a 'bower install' I have to pick
numerous dependencies for Polymer components.  opt 1 = Master, opt 2 =
the resolution i posted
[23:20:14] <organicHack> I tried option 1. and option 2.
[23:20:30] <organicHack> either way, i have quirks
[23:21:49] <Pomax> you shouldn't
[23:22:18] <Pomax> it should just be bower install --save
Polymer/polymer
[23:22:33] <Pomax> so not "bower install polymer"
[23:22:41] *** grogs_ has joined #polymer
[23:24:33] <organicHack> right!
[23:24:35] <organicHack> if i do that i get:
[23:24:36] <organicHack> Unable to find a suitable version for polymer,
please choose one:     1) polymer#master     2) polymer#>=0.3.0 <1.0.0
3) polymer#~0.3.0     4) polymer#~0.3.5
[23:24:51] <Pomax> which version of bower are you using?
[23:25:08] <organicHack> and it lists every Polymer component and what
it needs. its rather verbose.
[23:25:42] <Pomax> https://pastebin.mozilla.org/5932842
[23:25:49] <organicHack> 1.3.9. latest bower version
[23:25:54] <Pomax> no multiple choice, just an instant latest polymer
install
[23:25:59] <Pomax> try a "bower update" first
[23:26:55] <organicHack> ah, i get this:
https://pastebin.mozilla.org/5932853
[23:28:34] <organicHack> gotta step away a bit
[23:28:38] <organicHack> thanks for the help!
[23:28:44] <organicHack> (even after bower update still the same)
[23:29:22] *** dcherman2 has joined #polymer
[23:30:54] <Pomax> ah. Might be because of a preexisting entry in
bower.json, although I'm not sure
[23:31:18] <Pomax> I'd remove the polymer entry and see if bower install
Polymer/polymer (case sensitive) then finds only the latest one
