ffi missing as dependency

Try running wpscan or wpscan --help after installing the package:
<internal:/usr/lib/ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:38:in `require': cannot load such file -- ffi_c (LoadError)

I tried to add ruby-ffi as dependency, but it doesn't help. I guess this is because some of the ruby gems wpscan uses are installed with bundler.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
