Bundler could not find compatible versions for multiple gems that seem to fall within range of requirements

I'm trying to use a gem spree, which depends on kaminari (~> 1.0.1). In my Gemfile.lock, I have kaminari (= 1.1.1). This satisfies the requirement for spree, since it's greater than or equal to the last digit. However, I'm getting this error when I try to bundle:

spree

kaminari (~> 1.0.1)

Gemfile.lock

kaminari (= 1.1.1)

spree

Bundler could not find compatible versions for gem "kaminari":
In snapshot (Gemfile.lock):
kaminari (= 1.1.1)

In Gemfile:
activeadmin (~> 1.3) was resolved to 1.3.0, which depends on
kaminari (>= 0.15)

rails_admin (~> 1.3) was resolved to 1.3.0, which depends on
kaminari (< 2.0, >= 0.14)

spree (~> 3.5.0) was resolved to 3.5.0, which depends on
spree_core (= 3.5.0) was resolved to 3.5.0, which depends on
kaminari (~> 1.0.1)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.


I'm not sure why v1.1.1 doesn't satisfy the requirements for all the gems in question, since it seems to fall within the range for all gems in question. I tried running bundle update, but then I get a long list of gem incompatibilities, none of which make sense to me either, since their requirements all seem to fall within range of the version I have in my lock file. For instance,

These errors raise a whole new set of questions, since I don't see any conflicts in versions for any of the gems.

For activemodel, why can't it use 5.1.6? Doesn't that satisfy all the requirements?

activemodel

For activerecord, why can't it use 5.1.6? Doesn't that satisfy all the requirements?

activerecord

For activesupport, why can't it use 5.1.6? Doesn't that satisfy all the requirements?

activesupport

For kaminari, why can't it use 1.0.1? Doesn't that satisfy all the requirements?

kaminari

For spree_core, why can't it use 3.5.0? Doesn't that satisfy all the requirements?

spree_core

How does one go about resolving these issues? I've tried running bundle update for all gems and for individual gems, but I get the same error message either way.

bundle update

This satisfies the requirement for spree, since it's greater than or equal to the last digit.

That's not quite correct, the docs for Bundler's Gemfile state:

The specifier ~> has a special meaning, best shown by example. ~> 2.0.3 is identical to >= 2.0.3 and < 2.1.

~>

~> 2.0.3

>= 2.0.3

< 2.1

So in your case, for kaminari, ~> 1.0.1 would mean '>= 1.0.1' and '< 1.1', which (obviously) 1.1.1 does not meet.

~> 1.0.1

'>= 1.0.1'

'< 1.1'

1.1.1

As for the others, everything looks to me like it'd work, though I notice a lot of the ones failing need something to do with spree or kaminari, so maybe fixing the one will help those. The others could also (maybe) be cascading errors, kind of like a missing parenthesis or comma in one place can cause syntax errors through the entire file, maybe just the one error is cascading through the rest of the bundle, I'd take care of Kaminari and then see what you're left with.

gem 'kaminari', '~> 1.0.1'

bundle install

You have requested: kaminari ~> 1.0.1 The bundle currently has kaminari locked at 1.1.1. Try running 'bundle update kaminari' If you are updating multiple gems in your Gemfile at once, try passing them all to 'bundle update'

bundle update kaminari

gem install kaminari -v '~> 1.0.1'

rails_admin

kaminari (< 2.0, >= 0.14)

Have you verified whether the version of spree you're trying to install is compatible with the higher version of kaminari? try downgrading the kaminari gem to "~> 1.0.1" to see if that helps.

if that does not work, then another suggestion would be to run "bundle update" on your current gemset "before" you add "spree" to your Gemfile to make sure you are working with all the latest versions of your currently installed gems.
