Unable to activate middleman-blog-4.0.2

Actual behaviour

Have been experiencing problems with an existing site, so I decided to create a new one. But by the time I ran the middleman init I got the following error

middleman init /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/specification.rb:2290:in raise_if_conflicts': Unable to activate middleman-blog-4.0.2, because middleman-core-3.4.0 conflicts with middleman-core (~> 4.0) (Gem::ConflictError) from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/specification.rb:1410:in activate' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems.rb:220:in rescue in try_activate' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems.rb:213:in try_activate' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:126:in rescue in require' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:40:in require' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/middleman-core-3.4.0/lib/middleman-core/extensions.rb:66:in block in load_extensions_in_path' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/middleman-core-3.4.0/lib/middleman-core/extensions.rb:65:in each' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/middleman-core-3.4.0/lib/middleman-core/extensions.rb:65:in load_extensions_in_path' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/middleman-core-3.4.0/lib/middleman-core/load_paths.rb:39:in setup_load_paths' from /Users/andreamoro/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/middleman-core-3.4.0/bin/middleman:10:in <top (required)>' from /Users/andreamoro/.rbenv/versions/2.4.1/bin/middleman:22:in load' from /Users/andreamoro/.rbenv/versions/2.4.1/bin/middleman:22:in `

I have the same problem. Had to revert to 3.5.3.
