Installing Ruby Dev Kit on Windows 7

[Ash Mulekar]

I have Ruby 2.0 installed and running on my Windows 7 machine. I installed MySQL on my machine. Then I followed a tutorial here which instructs to use this command "gem install Mysql"
I installed the ruby dev kit on my machine and then when I typed the command on my machine into my terminal I see this:

So my questions is what should I do now? I dont know whats not working or where to begin?
Id really appreciate some help.

Thanks

Hello, the error message states that no compiler was detected, so that indicates no devkit was installed.

Did you follow the instructions listed in the wiki page?

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

If you're getting started with ruby and rails I would suggest you install ruby 1.9.3.

I will also recommend follow this tutorial to install mysql gem:

Hope that helps.

Hi Thanks for your response. 

After seeing this link:

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

Yes, I installed the DevKit now and tried to test that the installation was properly done by running this command:
"gem install mysql"

When I ran that I see this at my command line:

So I am still stuck in terms of being able to use Ruby to connect to MySQL. Not sure how to proceed forward from here.

Does anyone have some suggestions?

Thanks

Hello,

You're not stating what DevKit you downloaded, and there are different ones depending on the version of Ruby.

But if is not able to find the compiler, is because is the wrong one.

Please, look at the downloads page:

http://rubyinstaller.org/downloads

For Ruby 2.0.0 x64, you need a 64bits compiler.

Down this page, several and different versions of Development Kits (DevKit) are listed. Please download the right one for your version of Ruby:

• Ruby 1.8.6 to 1.9.3: tdm-32-4.5.2
• Ruby 2.0.0: mingw64-32-4.7.2
• Ruby 2.0.0 x64 (64bits): mingw64-64-4.7.2

Most likely you downloaded the wrong one.

Please review what you did, download the correct DevKit and force the installation.

Hi,

Thanks for your reply. Ive been going back and forth with this problem. Ive unistalled the devkit version and reinstalled another version. but I still cannot get any gems to download. Ruby is running, but the devkit is just not working out.

So let me start from scratch:

Q1) How do I uninstall the devkit version I have the right way? Im looking here and Ive done these steps however, I dont see a gcc.bat and other files mentioned in that link, so there is nothing to delete.(Looks like they may not have been installed in the first place)

Q2) this brings me to the next question. Maybe I installed the wrong version of devkit. But How do I find which is the right version for my machine?

Thanks a lot for helping.'

gcc.bat and others where tricks used by older versions of DevKit, if the file is missing, that is good :)

To change the DevKit you have installed, it is simple: you need to force the installation of the new one at the "install" command:

ruby dk.rb install --force

That will ensure this new DevKit gets in the right place.

Of course, this assume you have first:

- Extracted DevKit into a folder without spaces

- "CD" into that directory from the command prompt

- Executed "ruby dk.rb init"

- Verified the right path of Ruby is listed in config.yml (as indicated, see the "review" command)

(and then you can perform the install command mentioned before)

Q2) this brings me to the next question. Maybe I installed the wrong version of devkit. But How do I find which is the right version for my machine?

The "Right DevKit" is the one listed in the downloads page:

http://rubyinstaller.org/downloads

WHICH DEVELOPMENT KIT?

Down this page, several and different versions of Development Kits (DevKit) are listed. Please download the right one for your version of Ruby:

Ruby 1.8.6 to 1.9.3: tdm-32-4.5.2

Ruby 2.0.0: mingw64-32-4.7.2

Ruby 2.0.0 x64 (64bits): mingw64-64-4.7.2

In your case, if you download Ruby 2.0.0, you need mingw64-32-4.7.2

If you downloaded the 64bits version of Ruby (you can verify by doing "ruby -v" at the command prompt) you will need the 64bits version of DevKit.

In relation to mysql gem, I noticed that is not taking the --with-mysql-dir parameter in the newer versions of RubyGems, you can use --with-opt-dir instead.

See this thread for similar issue:

https://github.com/luislavena/mysql-gem/issues/23#issuecomment-21168293

Let us know if that helps and if not, please post back the following information:

- Version of Windows (if is 32 or 64bits too)

- Version of Ruby (use "ruby -v" and paste the entire output in your response)

- Version of RubyGems (use "gem -v" and paste it here)

- What version of DevKit did you download (and under which directory you extracted it)

- What are the contents of config.yml (the file that gets generated inside the DevKit directory)

- What is the entire output of "gem install --platform=ruby json"

That will help us assist you better.

Regards.

If you downloaded the 64bits version of Ruby (you can verify by doing "ruby -v" at the command prompt) you will need the 64bits version of DevKit.

===

You downloaded 64bits version of Ruby (x64-mingw32 is the 64bits version of the platform)

So you NEED 64bits version of the DevKit.

You downloaded the 32bits version.

Please: download the right one and proceed to install it again.

Also please read the entire instructions I provided before.
