kandi X-RAY | sdbm Summary
SDBM provides a simple file-based key-value store, which can only store String keys and values. Note that Ruby comes with the source code for SDBM, while the DBM and GDBM standard libraries rely on external libraries and headers.

QUESTION
I am a novice programmer trying to use a Jekyll theme for my Github blog. This is my first time using it... and I'm having problems with bundle exec jekyll serve
command.
(FYI, I'm using Windows OS.)
Here's the output:
...ANSWER
Answered 2022-Jan-27 at 06:04From what I understand, Ruby moves all stdlib parts into gems, some are "default gems", as in, they are normally installed with Ruby and don't need a reference in your Gemfile
, but some are "bundled gems" which also are installed with Ruby, but need a reference in Gemfile
. The problem stems from a fact, that with every Ruby release, some "default gems" become "bundled gems".
Such a situation happened with webrick
in the past.
In your case it's most likely that you need rexml, which just became a "bundled gem" in Ruby 3.0: https://stdgems.org/rexml/
All this about a theory, but a solution is pretty simple. You just need to do

For full transparency, I started learning about Cucumber an hour ago. I've been following a concise tutorial on using Selenium in Ruby with Cucumber and I've had no issues until this point.
In essence, I'm trying to run a test scenario(?) but I am receiving this error:

Answered 2021-Mar-18 at 15:18This is a RubyMine bug. Nothing we can fix on the Cucumber end.
You can either consult a non-recommended monkeypatch / hack. Or downgrade to an early version of Cucumber5.
See https://youtrack.jetbrains.com/issue/RUBY-27294 for more information, including other possible workarounds and a time-frame for the fix from Jetbrains.

I tried to create a website using Jekyll.
I used git clone
to copy jekyll-theme-hackcss,
and then followed instructions from the arch-wiki rubygems page to get the right gem packages.
From inside the cloned folder I used:

Answered 2020-Jun-23 at 05:04There may be one culprit gem here but you will run into this problem again and again unless you fix your underlying approach.
Look at your gems environment; all gems are installed into one folder, regardless of the project you’re working on. So, if you have two projects with conflicting dependencies you will get this problem again.
There are tools, like RVM, which let you create environments for each project. So, each project has its own separate collection of gems and even distinct versions of Ruby if you need 2.7 in one project and 2.5 for another.
See "Easy way to setting Ruby Version Manager (RVM) on projects" for how to use RVM and create a gemset for each project.
QUESTION
I'm having an issue with rbenv and what I believe is an issue is of require
trying to read from my system gems rather than from shims.
I'm trying to create a single script file without the overhead of needing bundle - though I've tried adding a Gemfile and put the script and Gemfile in the same directory.
Reproducible steps:
brew install rbenv
export PATH="$HOME/.rbenv/bin:$PATH"
in my.zshrc
- Add
eval "$(rbenv init -)"
to my.zshrc
- Source:
. ~/.zshrc
rbenv install 2.6.3
rbenv rehash
rbenv global 2.6.3
rbenv rehash
for brevity- Close terminal
- New terminal:
ruby -v
= "ruby 2.6.3p62"rbenv version
= "2.6.3 (set by $HOME/Desktop/.ruby-version)"
which ruby
= "$HOME/.rbenv/shims/ruby"gem env
