I installed shopify dashing on my localhost and it is working fine prior to google client api installation but after doing bundle for google-api-client version 0.9.pre3 it is showing error as in attached images. For rectifying this issue I installed dashing but unable to find the resolve this issue.
I think your install of dashing is out of date. Mine is at 1.3.4 but I was getting this error when I installed.
gem update dashing
should do the trick. Once I'd updated dashing some of the other gems needed updating as well. Not sure why the default install is an earlier version. I'm on Win7 with Ruby 2.0.0p647
