I am currently managing an installation of ruby 1.9.3 in red hat 5.
I have found that, during a specific gem install, ruby is trying to download and install the latest version of a particular required gem.
I have attempted to prevent the updating of gems using the --conservative flag, however, this does not seem to work.
The gem in question requires a specific version of launchy which, in turn, requires a specific version of addressable.
The versions of these gems that are already installed meet the requirements of the gem I am attempting to install. However, the gem command attempts to download and install the latest version of addressable.
This is a problem, because the latest addressable requires public_suffix, which only installs in ruby 2.x and greater.
The gem that I am trying to install is a custom gem, and thus I have modified the gemspec, and found that removing the launchy requirement fixes the issue. However, launchy is a required gem, so the requirement needs to stay in the dependency list.
Has anyone had any experience with dealing with this particular version of ruby and gem and found issues with dependencies?
I have tried going in and modifying gemspec for launchy and addressable in the installed gems dirs, but have found that the issue is with the gem install command attempting to update/install the latest gems despite giving it flags telling it otherwise.
ruby 1.9.3
gem 1.8.23
After some additional research prompted by the above responses, it was determined that an outdated version of Hoe was causing the generated gem to try and install the latest dependencies. After moving away from Hoe to manage dependencies and versions, my issue has been solved.
Some of the dependency management classes seem to behave quite differently, so that's probably the first place to look.
Use the -v flag to specify the exact version to install:
gem install your-custom-gem -v 1.1
I'm working on a project and we've just updated bundler to version 1.7.0. There was a few days of trouble in getting all the gemfiles/gemfile.locks in a correct state, but I'm still having trouble with one issue in particular.
If there are differences in Gemfile.lock, I check it out, and then bundle so that I will have the gems in the Gemfile. However bundle seems to always auto-upgrade my gems. For example:
Installing multi_json 1.10.1 (was 1.9.2)
The rest of my team is using 1.9.2 - there's a dependency in another part of the application or...who knows. I should be using 1.9.2, but bundler consistently 'auto-upgrades' everytime i run bundle. Is there a way to prevent this behavior? I'm using RVM 1.25.23
Bundler 1.7.0 has some bugs which can result in unexpected gem updates. Please try upgrading to the latest version (1.7.2 at the time that I write this).
See:
https://github.com/bundler/bundler/issues/3136
https://github.com/bundler/bundler/issues/3142
https://github.com/bundler/bundler/issues/3149
Try:
bundle install --frozen
This should prevent bundler to update the Gemfile.lock.
When I try to bundle install I get the following message:
Your Ruby version is 2.0.0, but your Gemfile specified 2.1.0
In my Gemfile I have the following:
ruby '2.1.0'
And when I run ruby -v in the console I get:
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin12.0]
What does Ruby 2.1.0p0 mean? What version should I have in my Gemfile and why does the error tell me I have Ruby version 2.0.0?
Run
gem install bundler
or
gem update bundler
which may fix your problem.
For all new installed versions of Ruby you should update or install a new bundler.
In the top-level directory of your project, create a file named .ruby-version containing (wait for it...)
2.1.0
That apparently is the cross-{rbenv,rvm} way of spec'ing the version now.
For me, none of the answers helped. I fixed it closing and opening again the terminal.
If you get this in a Rails project, and you recently upgraded your Ruby version you might have spring still running with the old version of Ruby.
./bin/spring stop
will fix this.
None of the other suggestions was working for me. On the server, I had to do:
rvm --default use [correct version number]
brew cleanup ruby worked for me as I use HomeBrew to install Ruby.
I recently updated Ruby through HomeBrew but HomeBrew did not remove the older version. brew cleanup ruby will delete the older version of Ruby.
the main reason for this problem is your machine and gemfile using a different ruby version
so there is multiple problems and solutions for this issue you can try the below solutions one by one
1- make sure your machine install and use the same version of your gemfile if your machine not using the same one try to install this version using rvm
$ rvm install ruby_version_you_want
make sure the version installed success by using this command
$ rvm list
and if the new version doesn't set as a default you can set it using this command
$ rvm --default use ruby_version_you_want
you can check the current ruby version
$ rvm current
$ ruby -v
2- if you have the same issue check your bundler
$ gem install bundler
or
$ gem update bundler
3- in some cases spring still using the old version so you need to stop it
$ ./bin/spring stop
4- another case you can type
$ gem pristine --all
and try to install bundle again
5- also in some cases after install the updated ruby version you just need to restart your terminal.
6- another solution but I didn't recommend it the top-level directory of your project, create a file named .ruby-version containing your active running ruby version
7- if you still have this problem try to remove ruby and install the updated version only
$ aptitude purge ruby
If you are using Capistrano you should also check your deploy.rb file for the set :rbenv_ruby configuration.
I got this after upgrading with ruby-install. Fixed this with:
gem install bundler
followed by:
$HOME/.rubies/ruby-2.4.1/bin/bundle
It shouldn't be necessary to specify the path as which bundle indicates it's already using this path. But it gives the version error if running bundle without the path. I don't know why?
Thanks for the info about installing / updating bundler but it didn't work for me.
I had to do rbenv rehash
If you are using rbenv to manage your ruby environments you can run rbenv local 2.1.0 within your project directory to set the version of ruby your gemfile asks for.
NONE of the above answers worked for me, but
$ gem pristine --all
did the trick for me
buona fortuna
I struggled with something very similar, just different versions. I finally fixed it by going to RubyGems and placing the latest version of bundler in my gemfile, which currently is:
gem 'bundler', '~> 2.1', '>= 2.1.4'
There was still an issue, but after that, I ran:
gem update --system
And it resolved the mixed-up versions of Ruby in the rails project folder. You may have to restart the terminal before you do this. Also, I commented out the bundler gem file, it appears the gem update --system command is what really resolved it.
I got it from here:
For more advanced projects .versions.conf is supported, where more than the Ruby version can be specified.
Generating .versions.conf:
rvm --create --versions-conf use 1.9.3#my_app
Example .versions.conf:
ruby=jruby-1.6.8
ruby-gemset=my_app
env-JRUBY_OPTS=--1.9
Make sure your server configuration points to the correct ruby installation.
I had already updated my Ruby version in the .ruby-version file and that didn't fix it. ruby -v also showed the correct version, but I had forgotten to update my server config.
For example, with rbenv, NGINX, and Pushion Passenger I had in my NGINX server block:
passenger_ruby /Users/myusername/.rbenv/versions/2.3.1/bin/ruby;
And I needed to change to...
passenger_ruby /Users/myusername/.rbenv/versions/2.3.3/bin/ruby;
Then restarted NGINX and it worked.
This could happen when you install new version of ruby and update .ruby-version and Gemfile to the new version without doing install all the gems for new version of ruby first. So do the
$ bundle install
and you might as well need to source .profile or restart your shell.
If you are using rbenv just run
rbenv local 2.0.0
Then
bundle install
I opened Gemfile and replaced 2.7.1 with my own version of ruby 2.7.0 Everything is okay right now.
Had the same problem and I'm working with rbenv
Those are the steps that helped me fix my problem:
First in terminal, type which bundle. For me this gave: /usr/local/bin/bundle
Again in terminal try which ruby. In my case this gave: /Users/Mahmoud/.rbenv/shims/ruby
The problem here thus is that bundle isn't using the same ruby version from rbenv. So the path needs fixing. In other words I need to tell my terminal to use the rbenv version of bundle when I use bundle install.
So step 3: For me I personally already had the path set in ~/.bash_profile:
export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"
but apparently this was not enough as I was using zsh. Had to add those same 2 lines to ~/.zshrc as well.
Restart terminal
Now bundle install is working as expected and which bundle gives:
/Users/Mahmoud/.rbenv/shims/bundle
indicating that the problem was just that bundle was using the wrong ruby.
So if you have this problem, just make sure ~/.bash_profile and ~/.zshrc have the correct path by adding the 2 lines indicated above. If this didnt work take a deep dive into paths to make sure that before starting which bundle gives the equivalent of:
/Users/Mahmoud/.rbenv/shims/bundle
Had the same error. Doing the following fixed it. I was using ruby 2.5.5 and rbenv. Upgraded from 2.5.1.
rbenv rehash
gem uninstall bundler
gem install bundler
gem install bundler:1.17.3 (my app needed specific bundler -v 1.17.3)
gem install rails
I solved this problem by updating my ruby version to ruby '2.4.0'
Then bundle install
Simply closing the terminal I was working on and opening a new one worked for me. Sometimes, updates are not effected immediately until a session is closed. I have found this as the case with many rails errors I faced.
I clean and install with that:
sudo gem pristine --all
and install again:
bundle install
I face the error msg
Your Ruby version is 2.5.1, but your Gemfile specified 2.3.0
and solved by the following steps:
open Gemfile which located at your directory.
change ruby '2.3.0' to ruby '2.5.1' and save the Gemfile
go back to items and run bundle update.
the issue is perfectly solved.
I'm trying to install the RubyInline gem, but to no avail. It says that ZenTest needs RubyGems between versions 1.8 and 2.1. I have RubyGems 2.1.7.
Is RubyInline/ZenTest working on making it compatible with the newer versions?
This is a known (and reported issue) that the author has commented on here:
https://github.com/seattlerb/zentest/issues/48
Feel free to 'watch' that thread for a posted release that fixes this.
What version of ZenTest are you running? The current is 4.9.3.
Try running gem out ZenTest or gem list ZenTest to see if yours is out of date.
You can update all your stale gems using gem up.
You can clean out the stale gems after that using gem clean.
I just installed Ruby 2.0.0 using rbenv and set it to the global ruby version for my system. Since 2.0 is compatible with 1.9.3, I tried to start up a Rails project with it, but got the following error. I did rbenv rehash after installing 2.0
The `rails' command exists in these Ruby versions:
1.9.3-p327
Does this mean that every gem I installed on my system with 1.9.3 has to be reinstalled if I wish to use it with 2.0?
As seen here:
You need to reinstall bundler for each version of Ruby you use. See Ruby versions where you have it installed:
rbenv whence bundle
See your current version:
rbenv version
Install bundler for that version, if missing:
gem install bundler
Yes. Rbenv (and RVM) have separate "gem home" directories for each installed version of Ruby. There may be ways to symlink certain directories to get them to share, but this will likely lead to problems, particularly with gems that include native C extensions, which may or may not compile and run cleanly in multiple versions.
If you have a Gemfile, easiest thing is to just bundle install again for Ruby 2.0, giving you duplicate copies of many gems and Ruby-2.0 compiled versions of any native gems.
Another solution to this is to copy (or reinstall) the gems from your previous version to the newly installed version. How to do that is answered in detail in this question, which has two scripts -- one to install from local cache, one to reinstall from the internet (mine).
