问题
I'm trying to run
env RAILS_ENV=test bundle exec rake db:migrate
and get the following error
Your Ruby version is 2.1.7, but your Gemfile specified 2.2.3
ruby -v
gives me
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin15]
I'm using rbenv, if that matters. rbenv versions gives the following:
system
* 2.2.3 (set by /Users/thatsme/Projects/demoproject/.ruby-version)
So I have no ruby 2.1.7 installed. Spring is not running and I've run rbenv rehash. Then bundler gem is installed.
I'm going nuts on this. Can somebody please tell me why the wrong ruby version is being used? Thanks!
回答1:
Assumption: You are using RVM. This means there's a ruby version installed outside of RVM. Clear your rvm rubies by running
rvm uninstall <ruby version>
once you have uninstalled all rvm rubies do ruby -v, if this returns an output specifying a ruby version then thats the root of the problem. Uninstall it with
sudo apt-get remove ruby
Now install your rvm rubies with rvm install <ruby version> and set it as default rvm use <ruby version>
Now install bundler
gem install bundler
And do bundle install

I had the same problem
I needed to run
bundle
to reinstall all my gems. then
bundle exec rails c

Running the command below helped me somehow:
rbenv exec gem install bundler
