This is on ubuntu 14.04 64-bit set up with SIFT and REMnux. What other information can I provide? Thank you

[svent]

It seems that the ruby gem 'therubyracer' has a problem with an already installed version of the gem 'libv8'. I cannot reproduce this problem right now, but removing libv8 and reinstalling therubyracer might solve to problem:

$ gem uninstall libv8
$ gem install therubyracer

Please note that this might have side effects on other programs depending on a specific version of libv8.

[DigiAngel]

Thanks for looking at this. Here's what I have: /var/lib/gems/1.9.1/gems/libv8-3.16.14.7-x86_64-linux /var/lib/gems/1.9.1/gems/libv8-3.3.10.4-x86_64-linux

To be honest I'm not sure if SIFT or Remnux installed this. In either case I will give the remove and install a go...thank you.

When I trying to bundle install it gives the same error. I'm trying to install it on Kali 2.0.

I follow the steps you mention above, unisntall libv8 and then install therubyracer but it still gives an error.

This is first error. When I apply the steps and trying to execute jsdetox, it still says there is a missing gems.

./jsdetox
[JSDetox] Loading framework ... Could not find gem 'therubyracer (= 0.9.8) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.

How should I fix this?

[svent]

I tested this on Kali 2.0 and ran into the same problems. Unfortunately, this dependency hell is hard to solve. As jsdetox should be used in a virtual machine anyway, I would recommend to use an Ubuntu 14.04 LTS installation.

On Kali 2.0, you could try to replace the line gem 'therubyracer', '0.9.8' in the Gemfile with gem 'therubyracer'. That way bundle install should work, but the v8 integration (for executing and tracing javascript code) will be somehow broken.

Thanks for sparing time. I use it on Ubuntu as you said.
