I added omniauth gem to my gemfile and tried to run bundle install, but got a message about incompatibility of rails and bundler versions. I tried to update rails, but got messages about incompatibility with other gems. How can I downgrade bundler to 1.0?
$ bundle install

Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 3.0.0) ruby depends on
bundler (~> 1.0.0) ruby
Current Bundler version:
bundler (1.1.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
and
$ bundle update rails

Try the following commands:
gem uninstall bundler
gem install bundler --version '1.0.0'

To install downgraded version of bundler, try:
gem install bundler --version '<= 0.10.6'
so you could have both version installed (check: gem list bundler
/bundler _0.9.26_ -v
), then run using that specific version, e.g.:
bundle _0.9.26_ install

There are some problem when we are trying to uninstall global bundler version. I solve this problem of my own technique. Follow the steps:
Step-1: run: gem list bundler
*** LOCAL GEMS ***
bundler (2.0.2, 1.17.3)
bundler-unload (1.0.2)
rubygems-bundler (1.4.4)
I have 2 bundler version here 2.0.2 and 1.17.3. Now I uninstall 2.0.2 because I will use 1.17.3. But when I am trying to uninstall 2.0.2 using this command gem uninstall bundler --version '2.0.2'
I find an error:
ERROR: While executing gem ... (Gem::InstallError)
bundler is not installed in GEM_HOME, try:
gem uninstall -i /home/habib/.rvm/gems/ruby-2.3.1@global bundler
because It is my global bundler. But Error message have the solution. then I try step 2.
Step-2: run gem uninstall -i /home/habib/.rvm/gems/ruby-2.3.1@global bundler
output: Successfully uninstalled bundler-2.0.2
step-3: I check my bundler list again run gem list bundler
*** LOCAL GEMS ***
bundler (1.17.3)
bundler-unload (1.0.2)
capistrano-bundler (1.2.0)
rubygems-bundler (1.4.4)
Here I have only one bundler 1.17.3
and I can use it my any project
check your bundler version: run bundler -v
output:
Bundler version 1.17.3
