ruby - Problems with bundle (Rails) -


i'm running ruby 1.9.3 , rails 4.0.0, , i'm starting learn how use ruby on rails. whenever type command create project: rails new blog error when bundle tries execute "bundle install" command:

bundler not find compatible versions gem "bundler": in gemfile: rails (= 4.0.0) ruby depends on   bundler (< 2.0, >= 1.3.0) ruby  current bundler version:   bundler (1.2.3)  gemfile requires different version of bundler. perhaps need update bundler running `gem install bundler`?

but command: gem list bundle returns: bundler (1.3.5, 1.2.3) , command: bundle -v returns: bundler version 1.3.5

i don't know why that's happening, appreciate help, thanks.

try check gemfile.lock used bundler version.

you can try uninstall old version: 

gem uninstall bundler --version 1.2.3
