i am trying to install ActiveAdmin Gem i get the following error. i am running it from the commandline
harsha#harshamv:~$ gem install activeadmin
ERROR: While executing gem ... (Gem::DependencyResolutionError)
conflicting dependencies arel (~> 2.0.2) and arel (~> 4.0.0)
Activated arel-4.0.0 via:
arel-4.0.0 (~> 4.0.0), activerecord-4.0.0.rc2 (= 4.0.0.rc2), rails-4.0.0.rc2 (< 4, >= 3.0.0), activeadmin-0.6.3 (= 0.6.3)
instead of (~> 2.0.2) via:
meta_search-1.0.0 (~> 1.0), activeadmin-0.6.3 (= 0.6.3)
If you are using Rails 4, you need to use >= 1.0.0.pre version of ActiveAdmin. The best way of doing that right now is:
gem 'activeadmin', github: 'gregbell/active_admin'
in your Gemfile.

This Rails version remembers the last mammoths so what did you expect? :)
First things first:
Double check you are not trying to build this project on the bleeding edge Ruby (3.x). Even the latest 2.x might be a problem with Rails that old. Google "Rails & Ruby compatibility" to check which Ruby version is recommended for this fossil and don't try to move too far ahead. Use some Ruby version manager to switch between versions easily (my choice is asdf, but more common rbenv or rvm work too).
If downgrading Ruby doesn't help, try removing Gemfile.lock (copy it somewhere just in case) and reinstalling dependencies. Bundler locks dependencies there to minimize the surface of dependencies' changes. This is a very good thing during the normal development cycle, but for "archeological excavations" like the one you have to work with this might be a problem. With the lock file removed bundler will re-evaluate the dependencies graph from scratch so most of the conflicts you see now should be resolved. Probably :)
Be ready that even after this, you might have conflicts that the bundler cannot resolve on its own (due to some older versions of dependencies that are unavailable anymore etc).
I'm having issues getting jekyll to run to create a GitHub Page. After following the instructions as listed in the documentation, I keep getting an error after I edit the Gemfile and try to run bundle update. The error is:
Bundler could not find compatible versions for gem "terminal-table":
In snapshot (Gemfile.lock):
terminal-table (>= 2.0.0)
In Gemfile:
github-pages (~> 215) was resolved to 215, which depends on
terminal-table (~> 1.4)'
I reinstalled terminal-table using 'gem install terminal-table', and listing my gems using 'gem list' I can see that I have version 3.0.1 installed, so I don't understand the error.
Thanks.

Just delete the .lock file and bundle install. You will get a new one.
I just change terminal-table (>= 2.0.0) in Gemfile.lock to terminal-table (~> 1.4). And that seems to work in my environment. Hope this can work for you!
First of all, I'm aware that I'm running the risk that this question is already answered somewhere else, but because I don't know the origin of this issue I'm not sure what to search for to find the answer.
The Problem
I'm running bundle and Jekyll locally, which works perfectly fine. But when I install on Travis-CI, it presents me with the error Could not find public_suffix-4.0.4 in any of the sources. However, public_suffix-4.0.4 is clearly in my Gemfile.lock.
My Question
What might be causing the problem and what hints should I look for to find an answer?

If another bundle install didn't work, delete Gemfile.lock then try specifying the version for public_suffix in Gemfile like so:
gem "public_suffix", "~> 4.0.4"
Then run:
bundle update jekyll
bundle install
bundle exec jekyll serve
I'm trying to setup github page using Jekyll, currently it is using minima theme, and I want to change it to jekyll-theme-hacker.
So, I went to Gemfile,
I added
gem "github-pages", group:jekyll_plugins
under the
gem "minima", "~>2.5"
And after saving it, I did
bundle install
But this gives me the error.
Bundler could not find compatible versions for gem "jekyll":
In snapshot (Gemfile.lock):
jekyll (= 4.0.0)
In Gemfile:
jekyll (~> 4.0.0)
jekyll-theme-hacker was resolved to 0.0.4, which depends on
jekyll (~> 3.3)
Running `bundle update` will rebuild your snapshot from scratch, using
only
the gems in your Gemfile, which may resolve the conflict.
I am very new to the Jekyll and Programming, I wonder why this happened.
As far as what I could figure out was, Bundler is a Gem management tool, which Gem stands for the library or module for ruby programming langauge. So what I was trying to do was trying to install all the necessary things for the my new theme.
However bundler could not find compatible versions for gem "jekyll".
What does this exactly mean? Do I need a different dependency of jekyll to use my new theme?
If it is so, How can I do it?
Thanks a lot in advance.

Edit your Gemfile to look like this :
source 'https://rubygems.org'
gem 'github-pages'
Remove your Gemfile.lock
Launch a bundle command.
That's it !
You're ready to deploy to github pages.
This is occurring because you are requesting conflicting versions of Jeykll. One option is to downgrade the version of Jeykll you are using by changing it in your Gemfile
-jekyll (~> 4.0.0)
+jekyll (~> 3.3)
and then running bundle update jekyll
If you wanted to run the latest version, you could fork the Gem, update the jekyll dependency version and test the changes. If it is working as expected you should submit a PR to the original repo and could use the fork while waiting for it to be merged.
Version 3.7 worked for me, you could try and check the same.
I need activerecord for rake, but when i try to install it it says:
activesupport-5.0.0.1 requires ruby version >= 2.2.2,
which is incompatible with the current version, ruby 1.9.3p484
I tried changing ruby with rbenv to 2.2.2
rbenv versions
outputs
system
* 2.2.2 (set by /home/user/.rbenv/version)
2.3.1
But when i go ruby -v it says
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
Also tried removing it but when i install rake
sudo apt-get install rake
and I get this output
The following extra packages will be installed:
libruby1.9.1 ruby ruby1.9.1
But, I need ruby version 2.2.2 or later to be active (ruby -v) to install active record so i can do the rake command.
You are messing things up.
sudo apt-get install rake
is a system wide debian package, that knows nothing about rbenv. Remove it as well as you have system ruby removed.
Afterwards, do:
rbenv global 2.2.2
gem install rake # ⇐ THIS
I had help with this one and resolved it. In my case i changed gemfile.lock from

BUNDLED WITH

And then installed activerecord and all other that i needed
gem install activerecord -v 3.1.3
sudo apt-get install libmysqlclient-dev
sudo apt-get install ruby1.9.1-dev
gem install activerecord-mysql2-adapter
gem uninstall mysql2
gem install mysql -v 0.3.11
And the rake worked.
rake db:migrate[]
Hope this will help someone! :)
