My goal is to use libmspack. It depends on ffi-compiler, I've forked ffi-compiler, to add some custom code, and I want libmspack to use my modified version.
I have a simple Gemfile:
source 'http://rubygems.org'
gem 'ffi-compiler', :github =>'survili/ffi-compiler'
gem 'libmspack'
When running 'bundle install', installation of 'ffi-compiler' completes fine, but 'libmspack' install fails with an error that it can't find 'ffi-compiler'.(LoadError: cannot load such file -- ffi-compiler/compile_task)
I've noticed that if I remove 'libmspack' from Gemfile, and try to install it using 'bundle exec install libmspack', it works fine.
Can someone explain, what is the correct way to achieve my goal, causing libmspack to use custom ffi-compiler gem ?
I've found this SO post, which asks the same, but has no answer: Gem::LoadError when using a git repo in Gemfile
Thank you in advance

I have been fighting this thing for days. I'm on rbenv and I have multiple rubies installed trying to get one stupid decade old app running.

Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 3.0.0) was resolved to 3.0.0, which depends on
bundler (~> 1.0.0)
Current Bundler version:
bundler (1.17.3)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (~> 1.0.0)', which is required by gem 'rails (= 3.0.0)', in any of the sources.
#thefonso, I manage multiple decade old apps running stable on Ruby 1.9.3-p551 daily. Here are a few things to ensure:
Make sure you're running latest release of Ruby 1.9 which is 1.9.3-p551. It needs to be installed with SSL/TLS patches as per below:
# Make sure you have latest OpenSSL
sudo apt-get purge -y libssl-dev
sudo apt-get install -y libssl1.0-dev
# Now install Ruby 1.9.3-p551
rbenv install --force --patch 1.9.3-p551 < <(curl -sSL https://git.io/JOtSv)
rbenv global 1.9.3-p551 # (optional)
rbenv rehash
# Now install Bundler 1.17.3
gem install bundler -v 1.17.3 --no-rdoc --no-ri
# Add require 'openssl' to .../versions/1.9.3-p551/bin/bundle file right under require 'rubygems'
# This command below will do it automatically for you as long as you provide it the correct file path
sed "/^require .*/a require 'openssl'" -i "PATH_TO_RBENV_DIR_HERE/versions/1.9.3-p551/bin/bundle"
# That's it! Run commands below to ensure you have patched Ruby 1.9.3-p551
rbenv rehash
curl -Lks 'https://git.io/rg-ssl' | ruby
Now that's out of the way, you can try installing rake 10.5.0
gem install rake -v 10.5.0 --no-ri --no-rdoc
A Gemfile.lock would avoid this problem. If you had one from the last time you ran this code, it would still have the appropriate versions for Rails 3 and Ruby 1.9. Bundler would follow the Gemfile.lock. Unfortunately back then it was not the practice to commit Gemfile.lock.
Since you don't have a Gemfile.lock you're in dependency hell. Bundler is trying to resolve the dependencies using each gem's own gemspec. It doesn't matter which gems you have installed. Where versions are specified it will use that. Where they are not, it will try to use the latest version. Most gems aren't thinking about Ruby 1.9 any more, or old versions of gems didn't have good dependency specifications, so there's going to be problems.
For example, Rails 3.0.0's rails.gemspec depends on railties 3.0.0. railties 3.0.0's railties.gemspec depends on rake >= 0.8.4. There's no upper bound, so Bundler grabs the latest rake and it doesn't work with Ruby 1.9.
To solve this you will need to add more versioned dependencies to your Gemfile. For example, rake 11 should work with Ruby 1.9. Try adding this to your Gemfile.
gem 'rake', '~> 11'
Or you can be super conservative and specify the exact versions you have installed.
gem 'rake', '0.9.2.2'
Run bundle. This should get you past rake and onto the next dependency problem. Add a version restriction for that and bundle. Continue until there's no more dependency issues. Check in the Gemfile.lock.
I am trying to bundle install a project running gem 'rails', '4.2.0'.
Running Bundle install, I get :
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.2.0) was resolved to 4.2.0, which depends on
bundler (>= 1.3.0, < 2.0)
Current Bundler version:
bundler (2.1.4)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (>= 1.3.0, < 2.0)', which is required by gem 'rails (= 4.2.0)', in any of the sources.
Thus I then try to install bundler v 1.3.0 to successfully bundle this gemfile : gem install bundler -v 1.3.0
gem list bundler shows me that I successfully installed bundler at v 1.3.0
Then when trying to bundle install with v 1.3.0 like this bundle _1.3.0_ install, I get Could not find command "_1.3.0_".
How can I successfully run bundle install with that specific version of bundler ?
Basically, you need:
Bundler (>= 1.3.0, < 2.0) installed on your local machine.
Ability to run that Bundler version.
Run that Bundler version to install other gems required by your app (bundle install).
First, check if you have successfully install Bundler (>= 1.3.0, < 2.0) on your local machine:
$ gem list bundler
You should see:
*** LOCAL GEMS ***
bundler (2.1.4, 1.17.3, 1.3.0)
If not, install it:
$ gem install bundler -v "<2" -N
# Install lasted bundler below version 2
# -N: No document
Second, check if you can run that Bundler version:
$ bundle _1.17.3_ -v
You should see:
Bundler version 1.17.3
If you installed Bundler 1.17.3 but cannot run "bundle 1.17.3 -v", there is something wrong with your RubyGems gem. Check if you installed updated version (latest is 3.1.3):
$ gem -v
Try to update the RubyGems gem, because it is the one help you run a specific gem version:
$ gem update --system
You should see:

/home/lqt/.rbenv/versions/2.7.1/bin/bundle
...
RubyGems system software updated
Check again if you can run a specific Bundler version:
$ bundle _1.17.3_ -v
If you see:
Bundler version 1.17.3
Then, step 3, just run Bundler 1.17.3 to install other gems:
$ bundle _1.17.3_ install
you can try to add this to your Gemfile,
gem 'bundler', '1.17.1'
then try these commands:
gem install bundler -v 1.3.0
gem uninstall bundler -v 2.1.4
bundle update --bundler
bundle install
You can install bundler version 1.3 this way:
gem install bundler -v 1.3
And then use that specific version for installing gems:
bundle _1.3.0_ [install]
Hope that helps!
There was a bug with bundler previously, if you're using the wrong version of ruby gems. Try
gem update --system
I keep getting following:
remote: Gem::InstallError: spree_core requires Ruby version >= 2.1.0.
remote: An error occurred while installing spree_core (3.0.4), and Bundler cannot
remote: continue.
remote: Make sure that `gem install spree_core -v '3.0.4'` succeeds before bundling.
when I run
gem install spree_code -v '3.0.4'
it is successful and afterwards when I run git push heroku master again I get the exact same error.
rbenv versions
shows following:
2.2.2 (set by /Users/Martijn/.rbenv/version)
Heroku needs the ruby version defined in the Gemfile, like:
ruby "2.2.1". More info: https://devcenter.heroku.com/articles/ruby-versions.
I'm going through the rails tutorial atm. (I'm a beginner so bear with me.)
As you can see below, when I try and install the rubygems using 'bundle install', I get the error message saying that I need to make sure 'gem install json -v '1.8.1' succeeds before I try again.
But when I try and sudo gem install json -v '1.8.1', I get the

If I'm asking a stupid question, or if I've left out any necessary info, just let me know. I'm new to this -- CodeAcademy & RailsForZombies are the extent of my knowledge.
