dbm's Introduction

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

Simple Syntax
Normal Object-oriented Features (e.g. class, method calls)
Advanced Object-oriented Features (e.g. mix-in, singleton-method)
Operator Overloading
Exception Handling
Iterators and Closures
Garbage Collection
Dynamic Loading of Object Files (on some architectures)
Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers

libgdbm-dev is installed, so all dependencies should be fulfilled to build the gem?

gem update dbm fails - wrong number of arguments (given 4, expected 1)

Hi,

I've never seen this error before!

I tried the suggested solutions in the previous thread: #8

But still not updating?

Clean install of Ubuntu 18.04.5 LTS on Vultr.

Ruby version 2.5.1 via sudo apt install ruby.

Any ideas?

$ gem update dbm
