Load error when running rails console

Question

I am using rails 4.1 and ruby 2.1.1 Everything works, but when I run rails console I get this error ``` > rails console Loading development environment (Rails 4.1.0) load error: /home/andreas/.rvm/rubies/ruby-2.1.1/.irbrc NoMethodError: undefined method `split' for nil:NilClass /home/andreas/.rvm/scripts/irbrc.rb:41:in `<top (required)>' ``` After the error the console opens and can be used. Here's the 41th line and surroundings in the .irbrc file. ``` 39 # Calculate the ruby string. 40 rvm_ruby_string = ENV["rvm_ruby_string"] || 41 (ENV['GEM_HOME'] && ENV['GEM_HOME'].split(/\//).last.split(/@/).first) || 42 ("#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}" rescue nil) || 43 (RUBY_DESCRIPTION.split(" ")[1].sub('p', '-p') rescue nil ) || 44 (`ruby -v` || '').split(" ")[1].sub('p', '-p') ``` I get these results when testing in the console ``` irb(main):008:0> ENV['GEM_HOME'] => "" irb(main):009:0> ENV['GEM_HOME'].split(/\//).last => nil ``` If I run irb outside the rails application, I get ``` 2.1…

If you encounter this problem you should restart you computer. If that does not fix it read on.

The bin/spring file sets ENV["GEM_HOME"] to a blank string

bin/spring

```
11 ENV["GEM_PATH"] = ([Bundler.bundle_path.to_s] + Gem.path).join(File::PATH_SEPARATOR)
12 ENV["GEM_HOME"] = ""
13 Gem.paths = ENV
```

This crashes when running rails console because in line 41

```
ENV['GEM_HOME'].split(/\//).last
```

returns nil if `ENV['GEM_HOME']` is blank

~/.rvm/rubies/ruby-2.1.1/.irbrc

```
39 # Calculate the ruby string.
40 rvm_ruby_string = ENV["rvm_ruby_string"] ||
41 (ENV['GEM_HOME'] && ENV['GEM_HOME'].split(/\//).last.split(/@/).first) ||
42 ("#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}" rescue nil) ||
43 (RUBY_DESCRIPTION.split(" ")[1].sub('p', '-p') rescue nil ) ||
44 (`ruby -v` || '').split(" ")[1].sub('p', '-p')
```

rvm uses the string to set the prompt message in the console. If you change line 12 in bin/spring to

```
ENV["GEM_HOME"] = "Spring is great!"
```

You get this nice prompt

```
bin/rails c
Loading development environment (Rails 4.1.0)
Spring is great! :001 > 
```

I don't really understand why `ENV["GEM_HOME"]` is set to a blank string. So, I just change this to get rid of the error. I have posted an issue on the spring github page.

Beware!

Any changes to the bin/spring file gets overwritten when you run the `spring binstub` command
