What do I do with this error when I run tests in rails?

问题

using ruby1.9.2 rails3.1.0

I am working from my netbook, so it is not my usual dev environment. I cloned a repo that I was working with on my desktop early this week. Now when I run rake test I get this error in the terminal.

Errors running test:units, test:functionals!

I followed the instruction and did gem install minitest , but still get the same result. Anyone know what to do here?

I just checked my gem list and it says minitest version 2.6.2 is installed. I don't know why the error is saying MiniTest v1.6.0 is out of date I am not using that version

回答1:

bundle exec rake test

Having a .rvmrc file in the project's root directory is handy for automatically setting the correct ruby/gemset. Also make sure your Gemfile/Gemfile.lock are using the correct version.

回答2:

I fixed it in the following way: add in your Gemfile following gem, Then run bundle install

group :test do
  gem 'turn', '< 0.8.3'
end 

回答3:

Here is how to fix it...
go to the root of your aplication and type:
gem install minitest
Then go to your gemfile located in the root of your app and add
gem 'minitest' at the bottom of the file.
