Error with the rubygems `plugin` keyword
I've recently added Diffend to my project, but am seeing the following error.
Is this the "not supported" part of the Appraisal README that says: "vendoring plugins is not supported"?
❯ bundle exec appraisal update
Found existing alias for "bundle exec". You should use: "be"
bundler: failed to load command: appraisal (bin/appraisal)

Would you say wrapping it in !ENV["APPRAISAL_INITIALIZED"]
is the canonical way of working with plugin
s?
I've not had the opportunity to work with a plugin
, but looking at this I think that's right: https://bundler.io/guides/bundler_plugins.html
You'll get a NoMethodError
, as Appraisal is trying to parse the Gemfile
by executing it.
I suspect wrapping it would work, yes. Give it a go and report back?
(It'd be nice to update README to link to this issue if indeed that's true!)
Having the same issue with diffend. I had hoped to add it to all my projects... but this will block a number of them.
