execjs: 2.2.1
ruby: 2.1.0
OS: Debian/testing on PowerPC

I am trying to use Jekyll (http://www.jekylrb.com) and I get the following error when I do
anything with it:

% jekyll --version

I have Rhino and Spidermonkey installed.   I have also installed therubyrhino as per the documentation.

This seemed to work for me: what I did is that I saw that it was asking for some execjs stuff so I ran the command % dpkg -l | grep execjs. I got nothing, so a did an apt-cache search and found the ruby-execjs package. After I installed that it all worked fine.

execjs: 2.2.1
ruby: 2.1.0.3
OS: Debian Jessie/8

(I feel bad that it took this long for you to get an answer)

Thanks for the tip, but this will not work on non-Intel platforms because
ruby-execjs depends on nodejs, which is Intel only.,
I am running on a PowerPC based G4 Mac.

Install therubyracer? therubyrhino is for jruby.

I did install therubyracer and still had no luck with it. At the moment I have stepped away from using
jekyll and am going with plain Emacs/org-mode based static publishing. This can be closed, unless folks want to keep it open.

I have the same issue on OpenBSD 5.6.

I have tried different options. I tried to intall libv8 with

pkg_add libv8
gem install libv8 -- --with-system-v8

Then I tried to install therubyracer through package.

pkg_add ruby20-therubyracer

After I installed therubyracer the simple example works fine in irb

require "execjs"
ExecJS.eval "'red yellow blue'.split(' ')"
# => ["red", "yellow", "blue"]

But I still get this error when I try to start rails (3.2.21) server.

rails server
/usr/local/lib/ruby/gems/2.0/gems/gems/execjs-2.2.2/lib/execjs/runtimes.rb:51:in autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable) from /usr/local/lib/ruby/gems/2.0/gems/gems/execjs-2.2.2/lib/execjs.rb:5:inmodule:ExecJS'
from /usr/local/lib/ruby/gems/2.0/gems/gems/execjs-2.2.2/lib/execjs.rb:4:in `<top (required)>'

I also tried to force runtime selection to ruby_racer and try to make sure that available? returns true.

export EXECJS_RUNTIME="RubyRacer"
irb
irb(main):001:0> require "v8"
=> true
rails server
/usr/local/lib/ruby/gems/2.0/gems/execjs-2.2.2/lib/execjs/runtimes.rb:65:in `from_environment': therubyracer (V8) runtime   is not available on this system (ExecJS::RuntimeUnavailable)
    from /usr/local/lib/ruby/gems/2.0/gems/execjs-2.2.2/lib/execjs/runtimes.rb:50:in `autodetect'
    from /usr/local/lib/ruby/gems/2.0/gems/execjs-2.2.2/lib/execjs.rb:5:in `<module:ExecJS>'

So it seems that something works but execjs still choke on start.

UPDATE:

This seems to work with Node runtime on OpenBSD.

pkg_add node

rails server
=> Booting WEBrick
=> Rails 3.2.21 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2014-12-15 22:01:16] INFO  WEBrick 1.3.1
[2014-12-15 22:01:16] INFO  ruby 2.0.0 (2014-05-08) [x86_64-openbsd]
[2014-12-15 22:01:16] INFO  WEBrick::HTTPServer#start: pid=7376 port=3000

So node runtime works. Still strange that I didn't get RubyRacer to work.

The v8 is issue on non-Intel platforms. Hence Fedora's ARM guys suggest to use WebKit's JavaScriptCore on ARM, provided by webkitgtk4-devel package. Unfortunately, the path [1] is hardcoded and Mac specific. Is there some way around?

Add "gem 'therubyracer'" on Gemfile works for me...

@welligton1993 adding that to the gemfile then using bundle install worked.

Reproduced using this tutorial code https://github.com/gotealeaf/bootstrap-todo-app
Fixed adding 'therubyracer' to Gemfile as workaround worked for me
