Ubuntu 16.04: Install problem

[skramm]

Machine: up-to-date Ubuntu 16.04

$ sudo apt install whatweb (goes on fine)

$ whatweb`
/usr/bin/whatweb: /usr/lib/ruby/vendor_ruby/rchardet/universaldetector.rb:39: invalid multibyte escape: /[\x80-\xFF]/ (SyntaxError)

`$ whatweb --version`
/usr/bin/whatweb: /usr/lib/ruby/vendor_ruby/rchardet/universaldetector.rb:39: invalid multibyte escape: /[\x80-\xFF]/ (SyntaxError)

And, in case this is useful (?) :

$ ruby --version
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]

Any idea ?

This looks like a problem with the rchardet gem.

Try gem uninstall rchardet if you don't need this functionality, or alternatively update ruby.

Thanks. Did that (uninstall rcharget), now works fine. Sorry, but I'm a complete Ruby noob! The only issue left is a warning (here with --version but happens with whatever command):

$ whatweb --version
/usr/share/whatweb/lib/tld.rb:85: warning: key "2nd_level_registration" is duplicated and overwritten on line 85
/usr/share/whatweb/lib/tld.rb:93: warning: key "2nd_level_registration" is duplicated and overwritten on line 93
/usr/share/whatweb/lib/tld.rb:95: warning: key "2nd_level_registration" is duplicated and overwritten on line 95
WhatWeb version 0.4.8-dev ( http://www.morningstarsecurity.com/research/whatweb/ )

Probably unrelated, but who knows? If not, I'll close the issue.

I see you are using an old version of WhatWeb. Did you install it using a package management system like apt?

One of the more recent releases will be faster, have more features, plugins, etc. https://github.com/urbanadventurer/WhatWeb/releases

Yep, as written in initial post ;-)

ok. So I first uninstalled previous version:

$ sudo apt-get remove whatweb
...
$ whatweb --version
bash: /usr/bin/whatweb: No such file or directory

Then fetched the latest tar.gz (0.5.1), untared, read the page: https://github.com/urbanadventurer/WhatWeb/wiki/Installation opened a shell into the folder, and here we go: (I gave the sudo passwd when requested)

Use `bundle info [gemname]` to see where a bundled gem is installed.

But:

$ bundle info whatweb
Could not find gem 'whatweb'.

However, the one in current folder works:

$ ./whatweb --version
WhatWeb version 0.5.1 ( https://www.morningstarsecurity.com/research/whatweb/ )

Maybe there are some clarifications needed in the install process ?(again, I hav no Ruby background at all, I have no idea what this "bundle" command does) Or did I misread something ?

Anyway, big thanks for what seems to be a great tool !
