I don't know if you have already fixed this issue but if not, please read this article . makandracards.com/makandra/… – Ezra 13/12, 2017 at 14:36

Does this answer your question? Your Ruby version is 2.0.0, but your Gemfile specified 2.1.0 – Warehouse 18/1, 2023 at 8:23

You better install Ruby 2.2.5 for compatibility. The Ruby version in your local machine is different from the one declared in Gemfile.

If you're using rvm:

rvm install 2.2.5
rvm use 2.2.5

else if you're using rbenv:

rbenv install 2.2.5
rbenv local 2.2.5

else if you can not change ruby version by rbenv, read here

Backward compatibility is not an issue, I think. If it were the opposite (Gemfile specifying 2.3.0 and only 2.2.5 installed) we would have some issues, for sure. – Reciprocate 20/6, 2016 at 5:22

@EddeAlmeida what if I don't want to change the Gemfile? Like it's a project with multiple people? Or an open-source project – Teenyweeny 20/12, 2016 at 2:50

Then install Ruby 2.2.5, create a private bundle for your app and go ahead, @EmileBergeron. – Reciprocate 20/12, 2016 at 2:55

These situations are exactly the reasons why I always suggest people to have a separate bundle to each application. – Reciprocate 20/12, 2016 at 2:58

I was having an issue between the local version of Ruby and the versions of Ruby that Heroku allows. I'm new-ish ro Ruby, Rails, and RVM, so this took me a bit to figure out. Thanks a TON, Tan. Specifically, no other answer I found in a couple hours of poking around mentioned the rvm use command. – Parasynapsis 20/1, 2017 at 15:24

this caused my mac to ask me to re install rails even though it's already installed "Rails is not currently installed on this system" – Genipap 17/5, 2017 at 1:36

rbenv install - doesn't work, install isn't a supported command. – Argillite 27/6, 2017 at 16:26

I tried the above on rbenv and it didn't work for me. Turns out I was using rvm and not rbenv although both were installed. Make sure you upgrade the right ruby version manager' ruby version – Hadron 21/2, 2020 at 23:23

after having installed it, rvm use 2.6.1 gives Required ruby-2.7.0 is not installed. :) how can I fix this ? – Weksler 27/2, 2020 at 22:33

This may be off topic for some users but I had to do these commands as well. rvm get stable --auto-dotfiles then bundler update --bundler ... and then, I could use rvm use 3.0.0 again, without errors/warnings – Cholinesterase 2/3, 2021 at 7:5

In my case adding correct paths ($HOME/.rbenv/shims and $HOME/.rbenv/bin) to my .zshrc fixed the problem. Thanks @Tan – Withal 28/5, 2021 at 22:9

If you have already installed 2.2.5 and set as current ruby version, but still showing the same error even if the Ruby version 2.3.0 is not even installed, then just install the bundler.

gem install bundler

and then:

bundle install

Pistole answered 7/8, 2017 at 10:17 Comment(6)

This is it right here! Because if you installed bundler before installing and setting your ruby version, calling bundle check or bundle install will still be referencing the ruby environment that was used for installing bundler originally. Cheers! – Hindmost 11/10, 2018 at 5:9

Btw, I also had to do rbenv rehash after reinstalling bundler. – Hindmost 11/10, 2018 at 5:10

Wow, I'd expect a missing gem error message then... anyway, thx! – Reiners 9/1, 2020 at 19:7

@Pistole I still get the same error after running the suggested commands – Canvass 7/4, 2021 at 6:6

@Canvass It's better to install and switch the ruby version (2.2.5) using rvm or rbenv as already suggested by Tan. Also, make sure to change the desired ruby version in the ".ruby-version" file. Thanks. – Pistole 25/4, 2021 at 17:6

I installed v2.7.5 using rvm but was getting the same error. Followed the above command and it worked – Highness 22/7, 2022 at 6:54

If you are using rbenv then make sure that you run the "rbenv rehash" command after you set local or global ruby version. It solved the issue for me.

rbenv rehash

@Duello I ran rbenv rehash but still get the same error – Canvass 7/4, 2021 at 6:6

I realized that you need to close the terminal as well after "bundle install" and "rbenv rehash" – Sadomasochism 18/3, 2022 at 15:2

Your Gemfile has a line reading

ruby '2.2.5'

Change it to

ruby '2.3.0'

Then run

bundle install

Reciprocate answered 20/6, 2016 at 4:44 Comment(8)

how to upgrade that? iam already installed railsinstaller from this link s3.amazonaws.com/railsinstaller/Windows/… – Glycine 20/6, 2016 at 8:8

I believe Aptana Studio has a command to update, but I never used it. – Reciprocate 21/6, 2016 at 18:34

Your suggestion didn't do anything for me, but running gem update fixed the error message for me. – Emanuel 29/4, 2018 at 2:59

Great that it is all fine now. Really sorry my suggestion didn't help. – Reciprocate 29/4, 2018 at 11:22

it provide another error 'gem file will remain installed in for inspection. an error occured while installing rjb -v '1.5.5' --source 'rubygems.org' succeed before bundling. – Applicator 16/8, 2018 at 8:34

is .ruby-version also related ? – Villiers 30/10, 2018 at 10:5

Yes, @AnthonyKal. .ruby-gemset states the name of the private bundle and .ruby-version the ruby version it will be based on. – Reciprocate 30/10, 2018 at 10:44

it can break any other gems installed and depends on the newer version. – Stingy 5/5, 2021 at 12:11

Had same issue. I'm using rbenv and which ruby would show the rbenv version:

/Users/Mahmoud/.rbenv/shims/ruby

which bundle though would show:

/usr/local/bin/bundle

After looking in every possible place, turns out my problem was that I needed to update path in ~/.zshrc in addition to ~/.bash_profile (where I originally had the changes)

if you're running zsh add those two lines in ~/.zshrc (or the equivalent file) in addition to ~/.bash_profile

export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"

After saving, quit terminal and relaunch before retrying. Hopefully this would help.

I just needed to set export PATH="$HOME/.rbenv/shims:$PATH" eval "$(rbenv init -)" to ~/.bash_profile – Sire 19/8, 2022 at 14:58

Not working in my case. I did the same – Beery 25/1, 2023 at 9:50

Worked for me. Thanks. I don't know why this isn't included in the rbenv docs. My project is a React Native project, if at all that helps someone else out there. – Evenfall 28/3, 2023 at 13:30

Two steps worked for me:

gem install bundler

bundle install --redownload # Forces a redownload of all gems on the gemfile, assigning them to the new bundler

I had this problem but I solved it by installing the version of the ruby that is specified in my gem file using the RVM

    rvm install (ruby version)

After the installation, I use the following command to use the the version that you installed.

    rvm --default use (ruby version)

You have to install bundler by using the following command in order to use the latest version

    gem install bundler

After the above steps, you can now run following command to install the gems specified on the gemfile

    bundle install

A problem I had on my Mac using rbenv was that when I first set it up, it loaded a bunch of ruby executables in /usr/local/bin - these executables loaded the system ruby, rather than the current version.

If you run

which bundle

And it shows /usr/local/bin/bundle you may have this issue.

Search through /usr/local/bin and delete any files that start with #!/user/bin ruby

Then run

rbenv rehash

it can also be in your capistrano config (Capfile):

set :rbenv_ruby, "2.7.1"

Add the following to your Gemfile

ruby '2.3.0'

Theodor answered 20/6, 2016 at 4:43 Comment(1)

How do you access your Gemfile and change this line. Is it a command that should be run? Is it done with a text editor? etc. – Brooking 1/4, 2022 at 10:26

I am on Mac OS Sierra. I had to update /etc/paths and add /Users/my.username/.rbenv/shims to the top of the list.

If you have some dependency on the version of the Ruby , then install the appropriate version. otherwise change the version in the gemfile in the current directory.

rbenv install <required version>
rbenv local <required version>

Even after installation it was showing the same error for me, so I just restart the mac, then do the bundle install, it works :)

it should show something like this

   <user>@<repo>% rbenv versions 
      system
    * 2.3.7 (set by <app>)

Nothing above worked for me.

My issue was : Your Ruby version is 3.2.1, but your Gemfile specified 2.7.6.

Below Solution worked for me :

Open project on VSCode
Click around 11th option (=ruby-version) On the left side menu
Change the current version to your current version (3.2.1) or whatever your ruby version is.
in terminal run command cd iOS
then run command bundle install
then run pod install
Sometimes pod will give error about installing boost, so run pod install again, just keep repeating the command until it install everything successfully.

Your app is ready to run smoothly.

run:

rbenv global

if old version then run: 1)

brew update

brew install ruby-build 2) brew install rbenv 3) rbenv install 2.7.5 4) rbenv init 5) rbenv shell 2.7.5 6) eval "$(rbenv init - zsh)"

list commands for rbenv - run simple:

rbenv

you can install simple way. Install rbenv On macOS with Homebrew.

brew install rbenv ruby-build
vi ~/.zshrc // open
eval "$(rbenv init - zsh)" // paste it
rbenv install 3.1.2
Close your Terminal window and open a new one so your changes take effect.

Really simple answer, better for teams with different versions of ruby, I would guess (good for development, maybe for high performance teams this isn't a good idea!). Change it to

ruby ">=2.2.5"

You better install Ruby 2.2.5 for compatibility. The Ruby version in your local machine is different from the one declared in Gemfile and then run:

rvm use 2.2.5

In my case i was not able to update my ruby version and rvm and rbenv didnt helped and it created lot of mess in envrionment variables, instead use this below solution, This worked for me:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" or use this link to install Homebrew - https://brew.sh/
brew install ruby follow the steps shown in terminal, i.e. echo path_shown_in_terminal and source path_shown_in_terminal

then just do ruby -v to check latest ruby version.
