/usr/bin/env: ruby: No such file or directory

Ruby

Hi

I am getting the error “/usr/bin/env: ruby: No such file or directory”
while trying to create a host in opennebula. ruby is one of the gems
required to install opennebula.

Can anyone help me on this

thanks in advance

regards
imaya

check your shebang line, it should be
“#! <path_to_your_ruby VM i.e. /usr/bin/ruby>”

On a terminal, try

/usr/bin/evn ruby
echo $?

127 – it could not find ruby, check your $PATH or, specify the
full_path_to_ruby
126 – couldn’t start, check with you system administrator to see is
there any restriction, e.g. SELINUX

Not necessarily. The env is a standard way of invoking ruby with the
current environment settings intact.

#!/usr/bin/env ruby

should work as is, provided you have ruby installed in a way that your
environment is aware of. It is the most portable of writing a script
header
in ruby, as it should work across all *nix systems that way.

For the OP, I have no idea what opennebula is. If it is some sort of VM
or
VPS thing, you may need to install ruby to begin with, but I have no
idea
what’s required to do so.

Well, that’s a good place to start:

ps. The command ‘ping -c 1 onehost’ might give you the answer in plain
English.

Thanks in advance

Hi,

mind you, that’s not a ruby related problem at all.

Learn to use a search engine, namely ‘Google’, to find solutions to
errors. Google gives this a third link (iirc)
What Does Destination Host Unreachable Mean? which explains what this
error is.
