Error for popen missing interactive slave

Hi, I'm getting this error when I try to do a completely different command (rails generate active_admin:install).

Any idea why rinruby is trying to automatically start up R?

Thanks, Joel

Do you have R on your path, right?
If not, you can use
require 'rinruby'
r=RinRuby.new(@eXecutable="/home/user/bin/R"

@clbustos Hi, is there any way I can avoid using r=RinRuby.new(@eXecutable="/home/user/bin/R"
I am receiving the same error when I deploy my app on the server..

No such file or directory - R --interactive --slave (Errno::ENOENT)

Even if I remove require 'rinruby', this error is popping up..

Any suggestions for this???

@kumarsaurabh20 I have the same problem. Did you manage to fix it? Thank you!

@pilarcormo I think I was getting this error because rails was not detecting R in the production environment. I did solve this problem by adding the following line in the .htaccess file in the public folder of my production server.

SetEnv PATH Path/to/your/server/R/bin
