I am trying to install gems for a new Rails project using bundler:
$ bundle install --path
I've set my local Ruby version to 2.3.1 using rbenv, but bundler is still using my system Ruby (2.0.0).
$ rbenv local
2.3.1
$ echo $PATH
/Users/jenniferpierce/.rbenv/shims:/Users/jenniferpierce/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/PostgreSQL/9.5/bin
$ which ruby
/Users/jenniferpierce/.rbenv/shims/ruby
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
$ bundle install --path
Your Ruby version is 2.0.0, but your Gemfile specified 2.3.1
My bash profile includes:
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
I've run:
$ rbenv rehash
and restarted my terminal. Maybe I'm missing something super obvious? Any ideas would be appreciated.
To add to this, in my case, I first had to run rbenv rehash and then install the bundler gem, and then re-run bundle install. Without all of those steps, it kept the same old Ruby version.
You should be able to just run bundle install without the --path. I believe --path allows you to specify a different path than the one in your system, but if you modified your bash profile as you suggested, there is no need for that.
Also, if you just changed your ruby version for the local folder, you should run a gem install bundler.

To start I follow the exact steps from Setup Ruby On Rails on
macOS 10.13 High Sierra, just like I have with every other version of mac/ubuntu.
So basically install homebrew, install rbenv ruby-build
add the following to bash profile and source it:
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
then do
rbenv install 2.5.1
rbenv global 2.5.1
ruby -v
outputs:
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
do a which ruby to to make sure:
/Users/pdavies/.rbenv/shims/ruby
run gem install
gem install rails -v 5.2.0
which outputs:
Successfully installed rails-5.2.0
Parsing documentation for rails-5.2.0
Done installing documentation for rails after 0 seconds
1 gem installed
then a rehash and check version:
rbenv rehash
rails -v
outputs:
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
found anther issue that suggested adding:
export PATH="$HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"
to the bash profile, did that sourced it and tried again still nothing. to check the output of echo $PATH was:
/Users/pdavies/.rbenv/shims:/Users/pdavies/.rbenv/bin:/Users/pdavies/.rbenv/shims:/usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin
Just to make sure i also did which gem incase i wasnt using the right one, output:
/Users/pdavies/.rbenv/shims/gem
when I do a which rails i get:
/usr/bin/rails
I found some blog that said to delete that, but I cant seem to do that either, i just get:
sudo rm -f /usr/bin/rails
Password:
rm: /usr/bin/rails: Operation not permitted
This is a fresh install of OSX and the only way I can get it work is to downgrade the version of OSX that is installed, which is a pain in the ass!
Any help would be grateful
Thanks
I am getting this error while running server, how do I fix this?
You better install Ruby 2.2.5 for compatibility. The Ruby version in your local machine is different from the one declared in Gemfile.
If you're using rvm:
rvm install 2.2.5
rvm use 2.2.5
else if you're using rbenv:
rbenv install 2.2.5
rbenv local 2.2.5
else if you can not change ruby version by rbenv,
read here
If you have already installed 2.2.5 and set as current ruby version, but still showing the same error even if the Ruby version 2.3.0 is not even installed, then just install the bundler.
gem install bundler
and then:
bundle install
If you are using rbenv then make sure that you run the "rbenv rehash" command after you set local or global ruby version. It solved the issue for me.
rbenv rehash
Your Gemfile has a line reading
ruby '2.2.5'
Change it to
ruby '2.3.0'
Then run
bundle install
Had same issue. I'm using rbenv and which ruby would show the rbenv version:
/Users/Mahmoud/.rbenv/shims/ruby
which bundle though would show:
/usr/local/bin/bundle
After looking in every possible place, turns out my problem was that I needed to update path in ~/.zshrc in addition to ~/.bash_profile (where I originally had the changes)
if you're running zsh add those two lines in ~/.zshrc (or the equivalent file) in addition to ~/.bash_profile
export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"
After saving, quit terminal and relaunch before retrying. Hopefully this would help.
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
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
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
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'
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>)
For $ Your Ruby version is 2.3.0, but your Gemfile specified 2.4.1.
Changed 2.4.1 in Gemfile to 2.3.0
Refer the below link to install the required version.
https://nrogap.medium.com/install-rvm-in-macos-step-by-step-d3b3c236953b
$ \curl -sSL https://get.rvm.io | bash
rvm install 2.7.1
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
I install rvm and rbenv it not help me so i go the project and open Gemfile change the ruby version with recommend version and than follow the command cd ios -> bundle install
Your project is ready to Run now.
Open Gemfile and find
ruby '2.2.5'
Change it to
ruby '2.3.0'
then install bundle
I have recently moved from RVM to Rbenv and when attempting to execute rails I am getting an error like the one below
Pauls-Air:~ $ rails
rbenv: rails: command not found
The `rails' command exists in these Ruby versions:
2.1.2
After installing a gem via the command line in a ruby version you have to execute rbenv rehash as described in the docs here and here
For example:
$ rbenv install 2.2.0
$ gem install bundler
$ rbenv rehash
$ gem install rails
$ rbenv rehash
You need to install Rails for each Ruby version within rbenv. Try running rbenv version, I might expect that 2.1.2 is not the ruby version in use for the current project (local version) or maybe your global version.
I ran into the same issue, but none of these other solutions (or any of the others I found elsewhere) worked. I was about to go back to RVM, so I decided to get rid of rbenv completely and it paved the way to the solution.
Try the following - it worked for me:
uninstalling rbenv, remove all references rbenv in your bash profile, and remove the remaining rbenv file folder and its contents.
Reinstall rbenv with homebrew.
Add it back to your bash profile:
export PATH="$HOME/.rbenv/bin:/usr/local/bin:$PATH"
eval "$(rbenv init -)"
Restart the shell:
exec $SHELL -l
Check the path:
echo $PATH
Install Rails:
gem install rails
rbenv rehash
Note: I consulted this for part of this answer: https://www.codementor.io/tips/3732499178/solution-for-rbenv-rails-is-not-currently-installed-on-this-system-to-get-the-latest-version-simply-type
Try to set up your environment with 2.1.2 version running this command line in your terminal:
$ rbenv shell 2.1.2
It works to me
Ensure that the .ruby-version file in your project's directory contains the same ruby version as the one you installed with rbenv.
For me, I set up my environment with the listed "The `rails' command exists in these Ruby versions".
$ rbenv shell 2.1.2
$ rails -v
It works.
Like for example if you want to install Ruby 2.5.3 with Rails 6
follow this way:-rbenv global 2.5.3
$ gem update --system
$ rbenv install 2.5.3
$ rbenv global 2.5.3
$ gem install rails -v 6.0.2.2
$ ruby -v
$ rails -v
The problem is that your global ruby version doesn't match your installed somewhere locally version which is 2.1.2. Try executing anywhere in bash shell:
rbenv global 2.1.2
That way rails will be found by rbenv in your $HOME directory and anywhere else.
rbenv global
Sets the global version of Ruby to be used in all shells by writing
the version name to the ~/.rbenv/version file. This version can be
overridden by an application-specific .ruby-version file, or by
setting the RBENV_VERSION environment variable.
I was using rails 4.1.7 with ruby 2.0.0 and have developed an application.
Recently upgraded to ruby 2.1.4 and made that as "Local" setting using rbenv. Now after doing "gem install rails", everything installed well.
Question is now if I try to run server, i am getting error
"Could not find rake-10.4.0 in any of the sources
Run bundle install to install missing gems."
bundle show rake reveals that its installed under
"bundle show rake
/Library/Ruby/Gems/2.0.0/gems/rake-10.4.0"
Shouldn't this be under 2.1.4?
Use rvm or rbenv to change ruby and gem space to another one. If you will begin usage of the them do the following (NOTE: If you already use one of them, just begin with point 2):
Install rvm with ruby:
$ \curl -sSL https://get.rvm.io | bash -s stable --ruby
or install rbenv, and then install ruby, and make it global:
$ \curl https://raw.githubusercontent.com/fesplugas/rbenv-installer/master/bin/rbenv-installer | bash
$ rbenv install 2.1.4
$ rbenv global 2.1.4
Enter to the project, create two files .ruby-version with just installed version of ruby (in example 2.1.4), and .ruby-gemset with name of your project:
$ cd project-folder
$ echo "2.1.4" > .ruby-version
$ echo "your-project-name" .ruby-gemset
Fix Gemfile with newly intsalled version of ruby adding a line:
ruby '2.1.4'
Reenter to the project folder, and rvm will generate its wrappers:
$ cd .. ; cd project-folder
Issue gem installation:
$ bundle install
New machine. New rbenv install. New rbenv-gemset install. New ruby-2.0.0 install. New rails 4.0.0 app.
When I
$ bundle install
from the rails app directory, I get
Your bundle is complete!
It was installed into ./vendor/bundle
But, if I then
$ gem list
none of the gems that were supposedly installed show up.
I have run
$ rbenv rehash
Why could this be?

Your default in this app is to install to vendor/bundle. You can tell this by It was installed into ./vendor/bundle text which appears after gems installation.
Bundler documentation specifies that you have to pass --system to install in system location:
--system: Install to the system location ($BUNDLE_PATH or $GEM_HOME) even
if the bundle was previously installed somewhere else for this
application
EDIT: More explanation is that your ruby knows only about gems installed with --system option when not using bundle exec. You can see your gems from vendor/bundle or whatever path you've chosen by running bundle exec gem list or (as Casper noticed) bundle list. Now it is your choice whether you want your gems in system location or in application directory.
