I am working on a Jekyll project and it builds/serves properly. When I add github-pages as a gem, I run bundle update because it needs to resolve dependencies. After doing so, I try to build and/or serve and it returns the following error while generating the static site:
jekyll 3.6.2 | Error: SyntaxError: Unexpected token: operator (>)
Here is my Gemfile:
source "https://rubygems.org"
# Hello! This is where you manage which Jekyll version is used to run.
# When you want to use a different version, change it below, save the
# file and run `bundle install`. Run Jekyll with `bundle exec`, like so:
#
# bundle exec jekyll serve
#
# This will help ensure the proper Jekyll version is running.
# Happy Jekylling!
# gem "jekyll", "~> 3.6.2"
# This is the default theme for new Jekyll sites. You may change this to anything you like.
# gem "minima", "~> 2.0"
# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
gem "github-pages", group: :jekyll_plugins
# If you have any plugins, put them here!
group :jekyll_plugins do
gem "jekyll-feed", "~> 0.6"
gem "jekyll-assets"
gem "jekyll-minifier"
end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
Here is the full output when I run build:

Does anyone know why this might be happening?
I've narrowed in on the github-pages gem as a cause for the issue but I'm not sure what the root cause is and how to resolve the problem.
I needed to add theme: minima back into my config. This appears to have resolved the build issues.

I want to customize my development environment with a few extra gems. I am using bundler with rails 3.0.x. I have those extra gems in my local system and i dont want to add them into my Gemfile. How can i by pass bundler and require these gems in my console which was opened using bundle exec ?
I found one way to do it, though it's a little hacky.
$ gem install gem_name
$ gem which gem_name
# outputs <full path to gem>/lib/gem_name.rb
$ rails console
> $LOAD_PATH << "<full path to gem>/lib"
> require 'gem_name'
I'm doing this to play around with different Ruby performance gems, although it might just be easier to add it to your Gemfile, bundle, and then revert before you push up your changes.
The command rails server throws this error.
C:/Ruby200/lib/ruby/gems/2.0.0/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2:in `require': cannot load
such file -- mysql2/2.0/mysql2 (LoadError)
I use Ruby 2.0.0 from RubyInstaller on Windows XP box.
I figured out what is the problem but I don't know how to solve it. The problem is that there is no any 2.0/ directory in the mysql2-0.3.11-x86-mingw32 gem. This is the gem that rails installs as its dependency from Gemfile:
GEM
remote: https://rubygems.org/
specs:
... many gems here
mysql2 (0.3.11-x86-mingw32)
... many gems here
DEPENDENCIES
...
mysql2
...
This is what is in that mysql2.rb file:
# C:\Ruby200\lib\ruby\gems\2.0.0\gems\mysql2-0.3.11-x86-mingw32\lib\mysql2\mysql2.rb
RUBY_VERSION =~ /(\d+.\d+)/
require "mysql2/#{$1}/mysql2" # <<-- this is that #2 line that throws an error
It is obvious that it takes the current Ruby version number and uses it as the path segment to reach some mysql2 file. In fact it is mysql2.so file. As I use Ruby 2.0.0 the path segment is 2.0:
mysql2/2.0/mysql2
Ok, now lets see how that directory of mysql2-0.3.11-x86-mingw32 gem looks like:
dir: C:\Ruby200\lib\ruby\gems\2.0.0\gems\mysql2-0.3.11-x86-mingw32\lib\mysql2\
No any 2.0/ directory.
I know the issue about libmysql.dll. I have it in my C:\Ruby200\bin. It doesn't help.
I read this answer https://stackoverflow.com/a/5368767/1114926 from the creator of RubyInstaller. I tried but it didn't help. It works for Ruby 1.9.3 because there is 1.9/ directory. But it doesn't work for Ruby 2.0.0.
How to solve it?

Thank you for your answer. I've tried. Unfortunately I have ERROR: Failed to build gem native extension. error:

It says:

But I have full DevKit installed, RubyInstaller installs it. Can't understand what else does it need.
I've already posted an issue to mysql2 GitHub page https://github.com/brianmario/mysql2/issues/364. No answers yet.
Had the absolutely same issue on Windows 7 x64 with Ruby 2.0.0 and DevKit 4.7.
The following steps helped me.
gem uninstall mysql2
Download last MySQL connector from http://cdn.mysql.com/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip
Extract it to C:\connector-6.0.2
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\connector-6.0.2\lib" --with-mysql-include="C:\connector-6.0.2\include" --with-mysql-dir="C:\connector-6.0.2"'
Or even shorter:
gem install mysql2 --platform=ruby -- --with-opt-dir="C:\connector-6.0.2"
uninstall mysql2-0.3.11-x86-mingw32, gems compiled before Ruby200 won't work. You have to compile it yourself.
If you run gem uninstall mysql2 and there is a non compiled version listed then just uninstall mysql2-0.3.11-x86-mingw32 - the compiled version else...
Installation
gem install mysql2 --platform=ruby. that would work.
Follow this guide on installing devkit http://rubyonwindowsguides.github.com/book/ch02-04.html.
Then try again.
Exactly the same behavior when I try to install Redmine on windows XP
when I try to do the "rake generate_secret_token", I got "cannot load
such file -- mysql2/2.0/mysql2 (LoadError)"
and when I try to re build mysql2 using --platform=ruby, I got the
same message as you green.
for the moment, I am stucked there ... but if anybody has anything to allow me to move forward, it will be very welcome.
I will keep informed as well

I almost done the same what #odiszapc described. Uninstall old gem, download mysql-connector-c-noinstall, unzip, but finally I used this command to build native gem:
gem install mysql2 --platform=ruby -- --with-opt-dir=/c/connector-6.0.2
(If you use git-bash then you can use unix style directory syntax.)
Copy paste from that link: https://github.com/brianmario/mysql2/issues/359. It worked for me.
If after installing the gem, you get an error:
"The specified module could not be found.
C:/Devel/Ruby200/lib/ruby/gems/2.0.0/gems/mysql2-0.3.11/lib/mysql2/mysql2.so"
That can be fixed by copying libmysql.dll to Ruby's bin folder.
I'm following the Michael Hartl Ruby on Rails Tutorial & there is a part where he is he he instructs you to update your Gemfile to include:
group :production do
gem 'pg', '0.12.2'
end
And then enter the below commands in your terminal:
bundle update
bundle install --without production
When you run the bundle update command it throws back the below errors.

An error occurred while installing pg (0.12.2), and Bundler cannot
continue.
Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.
sample_app:$
I was able to overcome this error easily be removing the 'pg', '0.12.2' gem from the Gemfile & replacing it after running the bundle update command. This seems to work fine as the 'pg', '0.12.2' gem is aslo omitted in the without production flag in the latter bundle install --without production.
The 'pg', '0.12.2' gem is only needed for deploying to heroku with the correct database & everything works fine even when I deployed it to heroku but I'm just wondering if this is an error in the Tutorial or am I missing something bigger here?
It's also annoying to have to remove this Gem everytime I run bundle update, is bundle update really that necessary?
Thanks in Advance
I'm following the same tutorial and I think it's redundant to run update without modifying existing dependency, but in this case it's even causing problems because update command has not --without argument.
I stumbled upon Rails 3 cheatsheet which mentions bundler workflow this way:
After adding or removing dependencies from Gemfile
$ bundle
Commit Gemfile and Gemfile.lock
After modifying existing dependency versions
$ bundle update
Commit Gemfile and Gemfile.lock
I read man pages for bundle update and tried RECOMMENDED WORKFLOW which consists of running bundle update after bundle install.
In my case (some output omitted):
$ bundle install --without production
Resolving dependencies...
Using rake (10.0.3)
...
Installing rspec-core (2.11.1)
Your bundle is complete!
Gems in the group production were not installed. <-- check
$ bundle update
Resolving dependencies...
Using rake (10.0.3)
...
Using uglifier (1.2.3)
Your bundle is updated!
Gems in the group production were not installed. <-- check
I tried it with new RVM gem set and everything was installed correctly.
After that Gemfile.lock contains pg (0.12.2) and deploying to Heroku works.
RECOMMENDED WORKFLOW
In general, when working with an application managed with bundler, you
should use the following workflow:
After you create your Gemfile for the first time, run
$ bundle install
Check the resulting Gemfile.lock into version control
$ git add Gemfile.lock
When checking out this repository on another development machine, run
$ bundle install
When checking out this repository on a deployment machine, run
$ bundle install --deployment
After changing the Gemfile to reflect a new or update dependency,
run
$ bundle install
Make sure to check the updated Gemfile.lock into version control
$ git add Gemfile.lock
If bundle install reports a conflict, manually update the specific
gems that you changed in the Gemfile
$ bundle update rails thin
If you want to update all the gems to the latest possible versions
that still match the gems listed in the Gemfile, run
$ bundle update
Installation of postgres fails with this error : "Can't find the 'libpq-fe.h header"
Looks like a lot of people faced this problem, good news is : stackoverflow has the answer ;)
Can't find the 'libpq-fe.h header when trying to install pg gem
(or at least it should help you to look in the right direction)
I have installed google api client with the following code and it installed successfuly.
gem install google-api-client
I am using rails 3.0.3 so i also included the above line bundler and ran bundle install which went successfully.
I have also rvm installed. And created a gemset.
And when I run the following command in the terminal:
gem environment | grep INSTALLATION | awk '{print $4}'
It gives me the following result
/home/jamal/.rvm/gems/ruby-1.9.3-p194
When i try to execute the following code in scintilla outside the project directory. It gives me an error.
require 'rubygems'
require 'google/api_client'
ERROR:
usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- google/api_client (LoadError)
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
What is the main reason of this kind of error?
Possible chances are your editor does not loading the specific gemset in which you install the gem.
Please provide output of gem list google-api-client -d in your questions. So that I can figure it out exactly what is going one.
EDIT:
Another issue which usually occurs are the dual installation of ruby. When we do have a system level installation and a rvm installation, many editor got confused in it. They load up original system installed ruby which do have prefixes like 1.8.7, 1.9.1and available in /usr/share/bin/. Where was you had installed the gem in rvm profile. To overcome this problem you must run your code from terminal after choosing the right gemset
I had that google/api_client (LoadError) message but, it concerned another Google gem.
gem 'google_drive', '~> 0.3.10'
gem 'google-api-client'
I just removed the , '~> 0.3.10' part in case of it was a compatibility problem. That did the trick:
Using google-api-client 0.7.1 (was 0.9.4)
Installing google_drive 1.0.6 (was 0.3.11)
I am trying to use the koala gem per these instructions: https://github.com/arsduo/koala/wiki
I did a gem install koala. I see the gem in the list of installed gems.
The instructions say to add
require 'rubygems'
require 'koala'
It doesn't say where. I tried it to add the lines to the beginning of one of my controllers.
Then I also tried it in the initializer file:
C:\Documents and Settings\mtariq\blog\config\initializers\koala.rb
I always get the same error:
no such file to load -- koala
I installed the gem.. so what 'file' is it trying to load?
Any help would be appreciated. I know I must be doing something stupid but can't find any clues.
Mariam
Assuming you are running rails 3, just add the koala gem to your Gemfile, then run 'bundle install'. No need to require any library.
# Gemfile
gem 'koala'
