Unable to install alchemy in spree (3.4.4) project

[amitbishtZT]

Hi,
I am unable to install alchemy (4.0-stable) in existing spree (3.4.4) with rails (5.1.6) solution.
getting below error-

Bundler could not find compatible versions for gem "cancancan":
In snapshot (Gemfile.lock):
cancancan (= 2.2.0)

In Gemfile:
alchemy_cms was resolved to 4.0.1, which depends on
cancancan (~> 1.9)

spree (~> 3.4.4) was resolved to 3.4.5, which depends on
  spree_core (= 3.4.5) was resolved to 3.4.5, which depends on
    cancancan (~> 2.0)

Alchemy 4.0 only supports CanCanCan (the authorization gem in use) 1.x, while Spree 3.4 only supports v2.x. We should be able to also support v2 in Alchemy 4.0.

@amitbishtZT this should now be fixed.

Hi , thanks .
I also fixed this particular issue but found that there were many other gems not in sync with spree's gems. Which are still not allowing me to install alchemy.

@amitbishtZT could you provide some more information? Which gems could not be resolved as well?

[amitbishtZT]

jquery-ui-rails needs to be 6.0.1
kaminari needs to be 1.0.1

@amitbishtZT

kaminari needs to be 1.0.1

This should be fixed easily, because Kaminari 1.0 did not make any changes that affect us.

jquery-ui-rails needs to be 6.0.1

This one is harder, because the changes made to jquery-ui-rails 6.0 are breaking 5.0 installs.

We plan to remove the jQuery UI dependency completely (see #1376), but this will not happen in a already published stable release (like 4.0-stable) but in an future release.

Until this happens we are willing to accept PRs that update the jquery-ui-rails dependency to 6.0 in the next minor release (4.1, still in beta), if someone want to work on this.

@afdev82 I added support for jquery-ui-rails 6.0 in #1420
