Ruby版本错误

Question

I'm using RVM with my 2.3.1@market gemset and getting error while trying to run my specs saying that

Your Ruby version is 2.3.1, but your Gemfile specified 2.0.0

So I added ruby '2.3.1' to my Gemfile but I'm still getting error that I need `2.0.0' anyway. I've also tried to reinstall bundler, which didn't help.

UPD: When I'm specifying any version than ruby '2.3.1' this line isn't ignored. For example if ruby '2.1.2' is specified then I'm getting error that

 Your Ruby version is 2.3.1, but your Gemfile specified 2.1.2

but when I'm specifying ruby '2.3.1' I'm getting

Your Ruby version is 2.3.1, but your Gemfile specified 2.0.0

Answer 1

try running

gem install bundler

or

gem update bundler

this may solve your problem

if that doesn't help then please check ruby -v for you project and make sure that you have ruby 2.3.1 installed for that you can use rvm install 2.3.1 and make if default to your project by echo 2.3.1 > .ruby-version
