Unable to pass command line arguments in Ruby 2.0.0

Question

I just installed Ruby 2.0.0 on Windows 7 (using "rubyinstaller-2.0.0-p247-x64.exe"). I think the File associations are OK:

$> assoc .rb
.rb = rbfile

$> ftype rbfile
rbfile="C:\Ruby200-x64\bin\ruby.exe" "%1" %*

However, I cannot pass any arguments to the interpreter.

So if I run a simple script (test.rb):

puts ARGV[0]

it gives nothing:

>test.rb test1
>

I guess I should add that I had Ruby 1.9.3 installed till yesterday. I uninstalled it, and installed the above (Ruby 2.0.0). Everything used to work fine in Ruby 1.9.3.

Please help !!

Thanks.

Answer 1

Other people had similar problems with Vista and Ruby 1.9 in the past. It seemed to be related to manual modifications or broken uninstalls of old versions.

A clean install of "rubyinstaller-2.0.0-p247-x64.exe" on Windows 7 works for me. The assoc and ftype commands do not know about ruby.

> assoc .rb
File association not found for extension .rb

> ftype rbfile
File type 'rbfile' not found or no open command associated with it.

I'd suggest you unset these values by starting a Shell as Administrator and running ftype rbfile= and assoc .rb=. If this doesn't help (make a backup and) delete all registry keys containing rbfile. The correct keys use RubyFile or RubyWFile. The InnoSetup Script contains the correct registry entries.

Worked for me in Windows 7:

• Run regedit
• Find HKEY_CLASSES_ROOT\Applications\ruby.exe\shell\open\command
• Make sure the "(default)" entry says: (Default) REG_SZ "C:\Ruby21-x64\bin\ruby.exe" "%1" %* When I checked, the %* was missing in mine. Of course, the ruby path must match where your ruby is installed.
