serve doesn't seem to work...

[TinajaLabs]

Going through instructions and when I get to this point, after installing the serve gem, and executing this command:

$ serve .

...it chokes with the listing below. Tried it with 2.12, 2.1.0, 2.0.0. I've posted an issue on jlong/serve#118 repo but no response so far.

Might there be another another approach to setting up graphene charts that does not depend on serve? Or a way to fix what looks like some kind of dependency problem?

Thanks in advance,
Chris.

on RHEL 6.5

Hey, thanks for trying out Graphene :)
Looks like you have a gem dependency problem. it should be easily solved with just doing a

$ bundle exec serve .

which would isolate the gems and use only those you need.
This kind of troubleshooting should help you with other projects as well - if you get the same kind of log or weirdness.

I must have really screwed up the ruby install on this rhel instance.

First I ran this as you suggested:

/opt/graphene/example # bundle exec serve .
Could not find coderay-1.0.9 in any of the sources
Run `bundle install` to install missing gems.

So I ran this (currently only user is root):

/opt/graphene/example # bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root
users on this machine.

I don't see serve in the list...?

Now when I run the command you suggested, it chokes.

Interesting. do you have the serve gem installed?

[TinajaLabs]

yes.

Maybe this helps:

/opt/graphene # rvm list rubies

Turns out, the problem was with the i18n gem. This fixed it for me.

gem uninstall i18n
gem install i18n -v 0.6.11

[TinajaLabs]

Worked for me, too. Thanks.

Now onto the fun stuff; hooking our graphite data into graphene.

/opt/graphene/example # gem uninstall i18n

You have requested to uninstall the gem:
    i18n-0.7.0.beta1

activesupport-3.2.19 depends on i18n (>= 0.6.4, ~> 0.6)
serve-1.5.2 depends on i18n (>= 0)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN]  y

As this is a javascript project, why not try with the npmjs package serve?

npm install -g serve
serve -s example

Note that I've not tried this on my behalf, but it's something that shocked me from the readme.... an npm package telling me to install a ruby gem 😕
