This is my first question, so be cool, mkay?
I have jekyll 3.3.1 installed, and jekyll-docs 3.3.0 seems to be the latest version. 'jekyll docs' fails with 'You must install the 'jekyll-docs' gem to use the 'jekyll docs' command.' I have installed jekyll-docs, so I'm not sure what the problem is. My research has indicated that jekyll and jekyll-docs need to be the same version in order to function properly.
Can anyone weigh in on this? Thank you!

I'm attempting to start learning Ruby on Rails via a YouTube tutorial series(https://www.youtube.com/watch?v=GY7Ps8fqGdc), but seem to be struggling getting everything properly installed and set up to do so. The tutorial requires MySQL with MySQL Workbench and Ruby on Rails. I've gotten several errors in the first few steps and taken some steps to try to resolve them, here's basically where I've gotten.
Installed the most recent version of MySQL and Ruby on Rails. I ran the rails new [name] -d mysql command without issue and it ran to completion. I then navigated to the newly created project folder and ran the bundle install at which point I was given the following error:
Gem::InstallError: nio4r requires Ruby version >= 2.3.
An error occurred while installing nio4r (2.5.2), and Bundler cannot continue.
Make sure that `gem install nio4r -v '2.5.2'` succeeds before bundling.
At this point I installed version 2.6 of Ruby on the machine, which did not seem to yield any improvements. Basically I think I'm overcomplicating all of this and want to know if anyone has an easy solution to install all the tools required for working in Ruby on Rails.
Thanks
First thing first, you're following a 5 yr old tutorial on youtube.
I would advise to always follow the newer ones even though some of the old ones might still work and the reason is simple; recent tutorials will probably work off the bat.
Now, judging by the video you shared, I can see that you should've installed RVM at some point. Official RVM website
In your terminal run ruby -v and check if you're actually using the Ruby version you just downloaded. To change the ruby version while using rvm you should use in your terminal:
$ rvm list
To check on your available ruby versions installed and then
$ rvm use <version>
This will switch your ruby version to the one you want. ( If you already installed it of course. ) and then try bundle install again.
Since you were asking for an easier solution I'd say to try following Rails official getting started guide. This guide installs the minimum amount of gems which will help you avoid all these version issues and even though it uses sqlite instead of mysql, later on you will be able to switch to mysql if you want with a better understanding of it.
I think I'm just at the finish line for installing jekyll on windows, It's connecting fine, but I'm getting an error message:
Liquid exception: No such file or directory - python C:/Ruby193/lib/ruby/ms/1.9.1/gems/pygments.rb-0.6.3/lib/pygments/mentos.py in _posts/2015-06-09-welcome-to-jekyll.markdown<-[0m done.
Please add the following to your Gemfile to avoid polling for changes: gem 'wdm','>=0.1.0' if Gem.win_platform
I'm not sure what messages I can ignore and what I need to fix. What do you guys think?
If adding this to my gemfile is as simple as entering a cmd prompt, what do I need to enter to install it?
This was an issue that was addressed by me by another question a few days ago.This is the original question and my answer.
Basically the issue here is that you need to install Python to use Jekyll on Windows because the code highlighter Pygments is written in Python, hence requires Python to function. Pygments is alsothe default code highlighter currently. In the future versions of Jekyll will use the Rouge highlighter, which is written completely in Ruby. This issue is tracked on GitHub.
To solve your current problem, you just need to install Python 2.x, which the official linked guide from the Jekyll documentation provides very clear instructions there. You will also need to install pip. I have also included alternatives in the other SO answer I have given, so I will just provide you the link to it to reduce duplicate information and copy-paste.
Once you have Python 2.x and pip set up, and install pygments, your Jekyll install should be up and running with the site template!
Regarding the Gemfile
A summary of what a Gemfile is: A file that lists all the required Ruby gems for a particular program. For example, you wrote a ruby program that depends on 10 other gems, rather than ask the user of your new gem to go download the previous 10 gems, and then later wrestle with outdated gem issues, a Gemfile is used to keep track of what gems are needed and version. The Gemfile is used by Bundler, which is also a gem that automatically keeps track of what gems you need. In the case of Jekyll, you can use a Gemfile to dictate what you want added into your Jekyll install or removed. This is used by GitHub to keep local versions of Jekyll and other gems updated with the version used by Github Pages.
As for that notification, all you would need to do to avoid polling for changes is:
Open notepad or text editor of choice.
Add this line: gem 'wdm','>=0.1.0' if Gem.win_platform, just that line of text. You can later add gems by typing in gem 'nameOfGem in a separate line.
Save the file as Gemfile in your Jekyll site's folder. Notice that there is not .txt extension, which you can create a file with no extension in notepad by choosing 'All Files' instead of '.txt' under 'Save As'. Or, you could just edit the file extension to remove the .txt.
Install bundler by executing gem install bundler.
Run bundle install to update the gems. If you're using GitHub, add the Gemfile and the newly generated Gemfile.lock into git.
The tags say it all, really. This is a project that used to work on earlier versions, but not now. If you know the answer, just stop reading and tell me how.
An existing project is working fine on older releases of NetBeans and MySQL. I am just trying to get it working on the latest release of everything. Nothing fancy. Just plain vanilla Ruby on Rails on Windows/MySQL.
Clean install of Netbeans 7.4. No problems.
Clean full install of MySQL 5.5. No problems. Includes Java connector.
Clean install of ruby and rails from community: http://plugins.netbeans.org/plugin/38549. No problems.
Everything is working just fine.
Webrick starts and runs. Absolutely no surprises to this point.
I tried to gem install MySQL: it fails, but it is not unexpected. I have no interest in pursuing that line. Ditto for MySQL 2. It's always hard building native libraries on Windows.
I tried to gem install all/any of the following:
* activerecord-jdbc-adapter
* activerecord-jdbcmysql-adapter
* jdbc-mysql
They install just fine, but the end point is always the same:
cannot load com.mysql.jdbc.Driver.
I think I know what this means, but I have no idea how to fix it. Is it a classpath problem? Is it a bug? Is it an incompatibility just about to be fixed? Is it because I'm using Windows? Who knows? I can't think of anything else to try, and the forums are full of these errors with no solutions that seem to fit my problem.
I am not sure, but maybe the blog post Installing MySQL on Windows 7 x64 and using Ruby with it will help.
Just started ROR Lynda Tutorial, Error while trying to execute the rails server in terminal.
New to ROR. Followed tutorial closely and installed all necessary gems and files. Creating a simple CMS. However I'm stuck with the following error.
$ rails server

Could not find gem 'mysql2 (~> 0.2.6)' in any of the gem sources listed in your Gemfile.
I have installed MySQL server version 5.5.13. I have Rails version 3. I have the MySQL(0.3.2) gem file installed. Any help would be appreciated. Thanks
The best way to fix this is to run
gem pristine --all
This rebuilds the Gems and should get rid of the error for you.
From the error I see that most likely your setup is not right. You should do a 'bundle check' to see if all dependencies have been met, I am quite sure they haven't. If you haven't yet done a 'bundle install' you need to do so, if you've done that already, then the problem is that bundler wasn't able to install mysql2 gem version 0.2.6 (it must be mentioned somewhere either in you Gemfile or somehow in the Gemfile.lock in case you've got that from somewhere else). So you would then either bundle install will fix it, or if not, then you should probably do a 'bundle update mysql2'
For the last several days, I've been struggling to get ruby on rails to work on my mac. The main culprit is MySQL. Every time I fix one thing, another error shows up. I upgraded/downgraded MySQL to play nice with ruby, rail and gems, but nothing. My latest error is:
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
/!\ FAILSAFE /!\ Wed Aug 05 21:09:23 -0700 2009
Status: 500 Internal Server Error
dlopen(/usr/local/lib/ruby/site_ruby/1.8/i686-darwin9.7.0/mysql.bundle, 9): Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib...
I don't have libmysqlclient.16.dylib; just *.15.dylib. Tried all the techniques, even installed or tried to install ruby-mysql-0.2.6 posted at tmtm.org
FYI: Last error prior to the one stated above had to do with authentication.
Appreciate any help.
Well, this question is a bit old already, but since I got here after getting the same error (but on LINUX), I would like to post my solution for future reference.
I simply had to install ruby-mysql.i686
yum install ruby-mysql.i686
Hope it helps somebody else in the future... tnx
Have you installed Xcode Developer tools? You can download it for free at http://developer.apple.com/.
Whenever I have issues with Ruby and MySQL, I never had Xcode installed. Could be wrong.
Answering my own question.
I don't know why and I don't know how, but took #Garrett's advice and re-installed Xcode. That didn't do anything. Went ahead and upgraded MySQL after that, which I had done before, and voilá! it worked. I'm guessing both re-installations finally got it working somehow. Weird!
Try using the below command . Provide the location of the mysql directory in your Mac .
sudo gem install mysql -- --with-mysql-dir= /usr/local/mysql
It looks like you haven't specified the location of mysql directory .
Good luck !
