How to change the default minimum version
After installing ruby 2.1.2 on my Macbook Pro, I found that the default minimum version is 4.7.5
, I am sodo gem install minitest
for installing minitest 5.4.2
, but the default gem is 4.7.5
. I also do gem cleanup
that does not uninstall the old version. I tried gem uninstall minitest -v 4.7.5
and got
RROR: While executing gem ... (Gem::InstallError)
gem "minitest" cannot be uninstalled because it is a default gem
So how can I change the default gem to version 5.4.2 and remove the old one? If I don't change this, I should write class AbcTest < MiniTest::Unit::TestCase
not class AbcTest < Minitest::Test
in my test. Or change the Gemfile every time I create a new project.

I had a similar problem: " How do I make a rake test not use the minimum minitest? "
You can delete the directory ~/.rbenv/versions/2.1.2/lib/ruby/2.1.0/minitest/
. Then your new minitest
gem will be used .
