Rbenv: Cannot load such file "script/../config/boot'

Created on 17 Sep 2015 · 4Comments · Source: rbenv/rbenv

I just moved from rvm`` torbenv```. I needed to install a newer version of ruby and I wanted to insulate the ruby that was running for a legacy Rails 2.3.15 application I have on this server.

I have had that legacy app working with Bundler for 2 years.

After reinstalling ruby, my Rails application refuses to load. I ended up installing a newer version of Ruby (2.1.5) since it was a nightmare trying to get any version of 1.8.7 (openssl issues) or 1.9.3 installed via rbenv. I don't think this is a shortcoming of rbenv, just configuration changes over the years.

Anyway, this 2.1.5 ruby version absolutely refuses to load the config/boot.rb file. Just flat out says it can't load it. Very unhelpful.

The require line that is failing in script/console:

require File.dirname(__FILE__) + '/../config/boot'
/home/myapp/.rbenv/versions/2.1.5/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- script/../config/boot (LoadError)

At the top of this script/console file is:

#!/usr/bin/env ruby

Could that somehow be causing a problem?

It's probably not impossible, but it's excruciatingly painful on RedHat. Lots of known issues with compiling against RH's OpenSSL with Ruby 1.8.7. I just have to last a little longer with this old app during the rewrite.

It's silly, but I was able to run this using:

./script/console

instead of just calling:

/script/console

Works like a champ.

In newer versions of Ruby, the current directory is no longer in $LOAD_PATH by default. That means that using require to load files relative to the current directory (such as script/../config/boot which expands to simply config/boot) won't work.

Your alternatives are:

edit $LOAD_PATH to include the current directory (by e.g. $LOAD_PATH << ".");
use require_relative "../config/boot" in script/console; or
just ditch script/console and use rails console which is the new way of starting the console in newer Rails versions.
