Unable to install gem ruby-debug19 on win7 with installed ruby 1.9.2 and 1.9.3

Question

I've tried many solutions but nothing seems to work! I use Ruby 1.9.3 and Rails 3.1.3 and I want to install the ruby-debug19 gem. This ist what I get from the PowerShell:

PS C:\Users\**\**\**> gem install ruby-debug19

ERROR:  Error installing ruby-debug19:

Answer 1

I've had a similar issue getting ruby-debug-base19x installed and I've been able to get it successfully installed using the following:

gem install ruby-debug-base19x -v 0.11.30.pre3

This worked on my development machine which is running window 7 along with pik (see https://github.com/vertiginous/pik), devkit (see https://github.com/oneclick/rubyinstaller/wiki/development-kit) and Ruby 1.9.3p0 / 1.9.2p290

Here's a sample of what you should see when installing it:

C:\>gem install ruby-debug-base19x -v 0.11.30.pre3

While this worked for me it is a moving target in that we're using a pre release version of the gem to get things done. Best to keep a eye out for a release.

Just an additional note that at the time of writing the current pre release was 0.11.30.pre6 which doesn't work so just doing the following will fail:

gem install ruby-debug-base19x --pre

Similar question was asked on jetbrains site, and its solution worked for me: http://devnet.jetbrains.com/message/5443846#5443846

You should install new linecache19 gem via

curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem

And then ruby-debug-base19x via

gem install --pre ruby-debug-base19x

Answer 3

Had a similar problem with Mac OS X rvm ruby 1.9.3-p0 and a gem install ruby-debug-base19x --pre did the trick.

This installs the pre10 release which seems to do the trick.
