Travis is running the the command below and throwing an error:
$ gem install bundler
217ERROR: Error installing bundler:
218 The last version of bundler (>= 0) to support your Ruby & RubyGems was 2.3.26. Try installing it with `gem install bundler -v 2.3.26`
219 bundler requires Ruby version >= 2.6.0. The current ruby version is 2.5.0.
Now I don't know who told it to do that when I have the following in the .travis file:
before_install:
- gem install bundler -v 2.3.26
What could be causing travis to behave like this?
I'm trying to install canvas lms , but I have faced with the following issue. Any help. enter image description hereplease
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
bundler (>= 2.2.17, <= 2.2.24)
Current Bundler version:
bundler (2.2.28)
Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with gem install bundler:2.2.24 and rerun bundler using bundle _2.2.24_ update
I tried updating bundle but no success yet.
Try the following:
gem install bundler -v 2.2.24
bundle _2.2.24_ install
I've just removed rbenv as i wanted to install a newer Ruby version (2.6) than the ones available for rbenv, then installed Ruby 2.6, that went fine, now while trying to reinstall all the gems for my app I ran into the following problem:
$ bundle install
Installing signet 0.14.0
Gem::InstallError: signet requires Ruby version >= 2.4.0.
An error occurred while installing signet (0.14.0), and Bundler cannot continue.
Make sure that `gem install signet -v '0.14.0' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
google_drive was resolved to 2.1.12, which depends on
google-api-client was resolved to 0.21.2, which depends on
googleauth was resolved to 0.6.7, which depends on
signet
But ruby has clearly been upgraded:
$ ruby -v
ruby 2.6.6p146 (2020-03-31 revision 67876) [x86_64-linux-gnu]
and if I try to install signet manually it works fine:
gem install signet -v '0.14.0' --source 'https://rubygems.org/'
Successfully installed signet-0.14.0
Parsing documentation for signet-0.14.0
Done installing documentation for signet after 0 seconds
1 gem installed
But then if i run bundle install again I still get the same problem. I've also tried bundle install --path vendor/cache and bundle install --system to no avail.
Note that the gems seem to install in the right place:
gem which signet
/var/lib/gems/2.6.0/gems/signet-0.14.0/lib/signet.rb
if I compare it to another one installed by bundler:
gem which multi_json
/var/lib/gems/2.6.0/gems/multi_json-1.14.1/lib/multi_json.rb
This is on Ubuntu 16.04.4 LTS and bundler 1.16.3
How do I fix this?
So I've finally figured it out, installing a newer version of bundler (but < 2.0 as Rails 4.2 requires it) did the trick, although i also had to uninstall the ruby 2.2-dev package and install the 2.6-dev package to be able to compile native gems like nokogiri, then running the whole thing specifying the bundler version.
For those interested, these were the commands:
apt-get remove ruby-dev
apt install ruby2.6-dev
gem install bundler -v 1.17.3
bundle _1.17.3_ install
bundler (2.0.1, default: 1.17.2)
How could I change the default to 2.0.1
Following https://bundler.io/guides/bundler_2_upgrade.html#upgrading-applications-from-bundler-1-to-bundler-2, here's what worked for me:
gem install --default bundler
gem update --system
bundle update --bundler
What helped me is to delete the current default manually from the folder
lib\ruby\gems\2.6.0\specifications\default\
and then install fresh bundler as usually
gem install bundler
or as default
gem install --default bundler
I had this same concern when trying to setup Bundler gem 2.2.11 as the default gem on my machine.
Here's how I achieved it:
First, I listed and uninstalled all other versions of the Bundler gem because I did not need them:
gem list bundler
gem uninstall bundler
If you encounter an error like this
Gem bundler-2.1.4 cannot be uninstalled because it is a default gem
Simply run the command below to get your ruby installation directory:
gem environment | grep "INSTALLATION DIRECTORY"
This should display an output like this. In my case my ruby version was 2.7.2:
- INSTALLATION DIRECTORY: /home/mycomputer/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0
Next, navigate to the specifications/default directory of the INSTALLATION PATH:
cd /home/mycomputer/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/specifications/default
Remove/delete the bundler.gemspec file that you have there. In my case it was bundler-2.1.4.gemspec, so I ran the command:
rm bundler-2.1.4.gemspec
Next, I installed the Bundler gem 2.2.11 and made it the default gem:
gem install --default bundler -v 2.2.11
Next, I listed my Bundler versions:
gem list bundler
Finally, I updated my gems to use the newly installed Bundler:
gem update --system
That's all.
I hope this helps
You need to remove .spec file to remove the gem.
Steps:
gem env – try to search in provided list under GEM PATHS, in specifications/default
remove there bundler-VERSION.gemspec
install bundler, if you don't have specific: gem install bundler:VERSION --default
gem install --default bundler:<version>
You need to know where the default specs are, so use gem environment to find out.
the steps I used were:
gem environment
# note INSTALLATION DIRECTORY
cd <installation_dir>
cd specifications/default
rm bundler-2.1.4.gemspec
gem install --default bundler -v 2.2.11
Remove all default bundler versions.
Commands:
$ gem environment
$ cd INSTALLATION DIRECTORY
$ cd specifications
$ cd default
$ rm bundler version
$ gem install bundler
