Incompatible with other omniauth solutions since version 2.10.0

[jonhue]

Because this gem now depends on the newest version of the omniauth-oauth2 gem (1.4), it raises an incompatibility issue if used together with other common omniauth authentication solutions like omniauth-facebook.

Source:

Bundler could not find compatible versions for gem "omniauth-oauth2":
In Gemfile:
omniauth-facebook (~> 4.0) was resolved to 4.0.0, which depends on
omniauth-oauth2 (~> 1.2)

omniauth-google-oauth2 (~> 0.4.1) was resolved to 0.4.1, which depends on
omniauth-oauth2 (>= 1.3.1)

omniauth-slack (~> 2.3) was resolved to 2.3.0, which depends on
omniauth-oauth2 (~> 1.3.1)

omniauth-stripe-connect (~> 2.9) was resolved to 2.10.0, which depends on
omniauth-oauth2 (~> 1.4)

Failed to install gems via Bundler.

The Pull Request #45 should fix the issue.

@jonhue While I could make changes and back down the requirement, there is no good reason to.

If their software isn't compatible with the newest version, it would be better for them to loosen their requirements, or upgrade.

The gem with the problem is omniauth-slack, by using the ~> operator with a fully declared version, they lock down to >= 1.3.1 and < 1.3.2. Everything else is very permissive.

• omniauth-facebook requires >= 1.2 and < 2.0
• omniauth-google-oauth2 requires >= 1.3.1
• omniauth-stripe-connect requires >= 1.4 and < 2.0

I would recommend opening an issue with omniauth-slack. I am closing this issue.
