Wpscan: Problems with ruby 2.4

[Mi-Al]

Hello! I run Arch Linux (with BlackArch repositories), after upgrading to ruby 2.4 I get the error at each WPScan operation, for instance:

`wpscan --help
[ERROR] cannot load such file -- xmlrpc/client

wpscan --update
[ERROR] cannot load such file -- xmlrpc/client
`
And the same error when I try to start scanning.
Here I read:

• XMLRPC is now removed from stdlib Feature #12160

I tried

gem install xmlrpc

I got

WARNING: You don't have /root/.gem/ruby/2.4.0/bin in your PATH, gem executables will not run. Successfully installed xmlrpc-0.2.1 Parsing documentation for xmlrpc-0.2.1 Done installing documentation for xmlrpc after 0 seconds 1 gem installed

So I did:

export PATH=$PATH':/root/.gem/ruby/2.4.0/bin'
export GEM_HOME=$HOME/.gem
export GEM_PATH=$HOME/.gem

Now I have:

wpscan --help
/usr/lib/ruby/2.4.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)
        from /usr/lib/ruby/2.4.0/rubygems.rb:298:in `activate_bin_path'
        from /usr/bin/bundle:22:in `<main>'

I tried:

gem install bundler
Successfully installed bundler-1.13.7
Parsing documentation for bundler-1.13.7
Done installing documentation for bundler after 6 seconds
1 gem installed

This does not make any affect.

WPScan version: community/wpscan 1:2.9.2-2

Is it possible to run WPScan with ruby 2.4?

ruby 2.4 is not yet supported as several required gems fail to compile due to the Fixnum and BigInteger change :/

I got the same error, I think that you have to downgrade your Ruby version for this to work.

Similar error, in my case, after install a fresh ruby 2.4:
/wpscan.rb -h
[ERROR] no library specified

[petercunha]

Got a solution for MacOS users. If you installed Ruby with Homebrew, run these commands:

brew update
brew remove ruby
brew install homebrew/versions/ruby23

Now, when you run ruby -v you will see that version 2.3.3 is installed. WPScan should now work, but you may need to run bundle install again.

@petercunha @cicadian314 @Mi-Al the latest version in master should support ruby 2.4.0. Can you please verify?

[petercunha]

Thank you @FireFart , I'll verify now

[FireFart]

@petercunha you need to run bundle install to install xmlrpc

[petercunha]

Oops. I forgot to run git pull. Stupid me.

Everything is working great now, thanks for the fast patch @FireFart

Thx @FireFart, soved with master latest version and bundle install.
