whatweb script complains about a missing dependency

[ghost]

Despite my having successfully run bundle install, whatweb keeps on complaining that the addressable gem is missing.

I'm on Debian 10.5.

Do you have multiple versions of Ruby installed?

Based on the output above, addressable was installed with bundle install, but it is not present in gem list.

If you're using multiple versions of Ruby, you will need to ensure you're installing the gems with the correct version of bundler.

ie,

bundle2.7 install
ruby2.7 ./whatweb

Yes, there are ruby2.1 and ruby2.5 installed. But while bundler depends on ruby2.1, both these commands somehow complain about missing dependencies:

$ ruby2.1 ./whatweb
WhatWeb is not installed and is missing dependencies.
The following gems are missing:
 - addressable
 - ipaddr

$ ruby2.5 ./whatweb
WhatWeb is not installed and is missing dependencies.
The following gems are missing:
 - addressable

There are no other ruby versions installed.
