Unable to install with --pre under Ubuntu: Asks for Ruby >= 2.0.0 when it’s 2.2.0

[kleinfreund]

Although I have Ruby 2.2 installed, the installation of Jekyll 3.0.0.beta is aborted due to the required ruby version being 2.0.0.

philipp@RAUMBASIS:~$ git --version
git version 2.3.2
philipp@RAUMBASIS:~$ sudo gem cleanup

That's gotta be a bug in RubyGems?

[kleinfreund]

I try to update Ruby and RubyGems. After that I’ll try using a different Ruby version with rvm (i.e. 2.1.5).

[envygeeks]

This might either be an edge on your system (what do you use to manage your Ruby? I build mine into /opt/ruby) or an edge in RubyGems. I just manually installed the gem on my system and it immediately let me remove it.

jordon@laptop:~/development/envygeeks/docker$ gem --version && ruby --version
2.4.6
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]

[kleinfreund]

I updated Ruby via rvm from 2.2.0 to 2.2.1. Also did sudo gem update --system which installed rubygems-2.4.6. Issue is not resolved by that.

Next thing. rvm install 2.1.5 && sudo gem install jekyll --pre. Same thing.

[envygeeks]

What is the value of $GEM_HOME?

[kleinfreund]

philipp@RAUMBASIS:~$ echo $GEM_HOME
/home/philipp/.rvm/gems/ruby-2.2.1

(Changes accordingly when I do rvm use 2.x.x)

[envygeeks]

For now since I don't know how this bug is existing lets just see if we can work around the edge:

find ${GEM_HOME} -type f -name jekyll.gemspec -exec sed -i 's/10 s/^/#//g' {} \; && gem uninstall jekyll

[kleinfreund]

philipp@RAUMBASIS:~$ find ${GEM_HOME} -type f -name jekyll.gemspec -exec sed -i 's/10 s/^/#//g' {} \; && gem uninstall jekyll
Remove executables:
    jekyll

in addition to the gem? [Yn]  y

Got it running under OS X (same Ruby/RubyGems version) in the meantime without issues.

[envygeeks]

Perhaps @mpapis or @drbrain can provide some insight? Since both of their softwares are included.

[envygeeks]

Also @kleinfreund we provide a jekyll binary for Ubuntu now (with isolated Ruby and packages) in the meantime while I try to figure out how this is happening perhaps you can use that: https://github.com/jekyll/jekyll/releases/tag/v3.0.0.beta2

[mpapis]

drop the sudo and try: gem install jekyll --pre - when you run with sudo it goes to system ruby so you would need to check sudo ruby -v and sudo gem -v

[kleinfreund]

@mpapis Yikes, I always felt that this was not the right way to handle things, since installing Ruby Gems on OS X always worked without sudo. Best thing would be to reinstall the whole stuff without sudo, huh?

@envygeeks Thanks for you help, I’ll first try to get Ruby/RubyGems to work on Ubuntu without sudo as this seems to be the more logical approach. I’ll come back to the binaries later.

[kleinfreund]

Alright, it worked. What did I do?

• rvm remove 2.2.1 && rvm remove 2.1.5 to remove the current rvm rubies I had
• rvm install 2.2.1 to reinstall the latest Ruby version
• gem install sass jekyll-sitemap jekyll-sass-converter jekyll to install my default gems
• gem install jekyll --pre to install beta (which strangely is beta1, should it not be beta2?)
• gem uninstall jekyll -v 2.5.3 && gem uninstall liquid -v 2.6.2 to remove conflicting gems

Thank you guys for your help 👍

[envygeeks]

Closing this ticket now then. Glad it's fixed! Thanks @mpapis

[parkr]

It was the uses of sudo, yep glad you guys got this fixed!

Same here. Thanks!
