使用错误的ruby版本运行的bundle命令

Question

I have installed 2 ruby versions on my using rbenv mac - 2.3.7 and 2.4.5

If i run command ruby -v following is the output:

ruby 2.4.5p335 (2018-10-18 revision 65137) [x86_64-darwin18]

But if i run bundle install from my project, i get following error message:

Your Ruby version is 2.3.7, but your Gemfile specified 2.4.5

I have used rbenv to install different ruby version.

Answer 1

Try to add a .ruby-version file on your project's root:

$ echo 'ruby-2.4.5' > .ruby-version
$ cd .

That will set your Ruby version properly.

Answer 2

You're probably running a version of Bundler that was install using a different Ruby version. You can try reinstalling Bundler in your project folder:

gem install bundler
