I would like to install gem 'faker', '1.7.3' in Chapter 10 of the rails tutorial. Bundler could not find compatible versions for gem "i18n":
In snapshot (Gemfile.lock):
i18n (= 1.7.0)

In Gemfile:
jbuilder (~>2.5) x64-mingw32 was resolved to 2.9.1, which depends on
activesupport (>= 4.2.0) x64-mingw32 was resolved to 5.2.3, which depends
on
i18n (<2,>= 0.7) x64-mingw32

faker (= 1.7.3) x64-mingw32 was resolved to 1.7.3, which depends on
i18n (~>0.5) x64-mingw32

Runningbundle updatewill rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict

    Specified faker version is very old. The latest version is 2.7.0.
    Why don't you specify the version and try the installation?
