Your Ruby version is 2.6.0, but your Gemfile specified 2.5.0

Question

Having trouble doing bundle. My project is using 2.5.0 but every time i do ruby -v it gives me ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin18]

I am using rbenv and my rbenv local is 2.5.0 and rbenv global is 2.5.0

Every time I do Bundle gives me an error Your Ruby version is 2.6.0, but your Gemfile specified 2.5.0

I have tried gem install bundler but it doesn't solves the problem.

source 'http://rubygems.org'

ruby '2.5.0'
gem 'rails', '5.0'

and my .ruby-version is also 2.5.0

Solution 1

Run

gem install bundler

or

gem update bundler 

which may fix your problem.

Solution 2

I'm using macOS and managed to solve this problem by using rvm first to install the desired ruby version (2.5.7 in my case).

Step-by-step:

• Install rvm from rvm.io - rvm version may be udpated with:

rvm get head

• Add rvm to your shell configuration, e.g. ~/.bash_profile:

PATH=$PATH:$HOME/.rvm/bin
source /Users/<YOUR_USER_NAME>/.rvm/scripts/rvm

• Using rvm, install new Ruby version:

rvm install ruby-2.5.7

• Set the current/default version:

rvm use ruby-2.5.7 --default

• Modify your Gemfile to use the new Ruby version. E.g.:

ruby '2.5.7'

• Refresh the current Ruby version based on ./Gemfile by running:

rvm reload

• After installing a new version, from your project dir do:

gem install bundler
bundle update

Do you mentioned any ruby version in your gemfile? Something like ruby '2.0.0', :patchlevel => '353' in your Gemfile

[bilal]

just updated my question and yes i do mention ruby version in gemfile

[mogbee]

Did you add "export PATH="$HOME/.rbenv/bin:$PATH" in your .bashrc or etc?
