Unable upgrade rails from 5.0.6 to 5.1.4

Question

I'm using ruby 2.4.2 and rails 5.0.6(system running well), and I'm trying to upgrade to rails 5.1.4, I changed Gemfiles from from gem 'rails', '5.0.6' to gem 'rails', '5.1.4', and run bundle update,

my question is when I did bundle update, Why redis-namespace downgraded to version 0.4.3 and resque downgraded to version 1.8.2 see trace console below.

Using redis 4.0.1 (was 3.3.5)
Using redis-namespace 0.4.3 (was 1.5.3)
Using resque 1.8.2 (was 1.27.4)

this causing I cannot run rails server, Thank you.

Bundler could not find compatible versions for gem "redis":
  In Gemfile:
    redis (>= 4.0.1)

    resque (~> 1.27.0) was resolved to 1.27.4, which depends on
      redis-namespace (~> 1.3) was resolved to 1.3.1, which depends on
        redis (~> 3.0.0)

Answer 1

After did another researched and another error message I just found that for rails 5.x should use redis-rails instead of redis and another issue that I found today also json (needed by resque gem and sdoc), make sure gem 'json' with version >= 2.1.0 listed in Gemfile, if not usually bundler will install version 1.8.6 (which generate an error with rails 5.x), so for I found these 2 errors, I will update my answer in case I found another

Gemfile

gem "redis-rails"
gem 'json', '>= 2.1.0'
