Can't install due to tzinfo error

[FarmerKJS]

I am trying to install Thingspeak on a pc running Ubuntu 14.04. Everytime I try I get this error: Fetching tzinfo-data 1.2013.8 Downloading tzinfo-data-1.2013.8 revealed dependencies not in the API or the lockfile (tzinfo (>= 1.0.0)).

Either installing with --full-index or running bundle update tzinfo-data should fix the problem.

In Gemfile: tzinfo-data

I tried to do the bundle update like it says to but then it just brings up the same error again. Any help is appreciated!

What worked for me, and I also read on another site: go into the Gemfile.lock search for tzinfo-data change the version from 1.2013.8 to 1.2017.3 or whichever version is the newest

You can look the newest version up here

After this run "bundle install" again
