Errno::ENOEXEC

ruby-talk
1

I have the following line in my code:
puts `bundle install`

This gives me the following error:
C:/../<abc>.rb:11:in ``': Exec format error - bundle install
(Errno::ENOEXEC)

Im using a windows machine. What could be wrong?
Have anyone faced this issue?

Any reason you're using `backtics` around your string? If you're just
trying to print to console, use 'single' or "double" quotes. If you're
trying to execute an external command, then that command needs to be
installed.

Try it like this to just print to console:

puts 'bundle install' #using single quotes

When I use backtics on my linux machine, this lists the contents of the
current working directory:

puts `ls` #using backtics indicates system command

Hope this helps,
Alex

Thanks for you reply.
And yes, I am trying to execute a command.
puts `ls`, works for me.
install bundle works for me from command line.
But I want to execute it from ruby code.

I did not understand "then that command needs to be installed"

Do you have the path to the executable listed in your $PATH environment
variable?

Which version of ruby are you using? You may need to run something like:

puts `bundle.bat install`

Hi Alex

I am facing similar issue and I do have $PATH variable setup in the
windows.
Basically, it happens, when I run cucumber features on culerity gem.
Error is:

(::slight_smile: failed steps (::slight_smile:

Exec format error -
C:/Ruby/lib/ruby/gems/1.8/gems/culerity-0.2.10/lib/../bin/run_celerity_server.rb
(Errno::ENOEXEC)

The only line in run_celerity_server.rb I could see is:
#!/usr/bin/env jruby
require File.dirname(__FILE__) << '/../lib/culerity/celerity_server'
Culerity::CelerityServer.new(STDIN, STDOUT)

Thanks in advance.

Running ruby scripts are a bit different. You may want to try adding
'ruby ' to the begining
