Artify Environment

Setting my own environment: Visual Studio Code, Git and Bundler

First, I create a repository in Github.

Then, I create a new folder in my laptop where I want to clone the repository.

I open this folder in my VS code and open the terminal (ctrl + `).

I run: git clone + the https from the repository.

When I make changes:

First, I stage this changes.

Second, I write commit message and commit.

Third, I push my changes.

Installing Bundler

First I make sure I have the latest version of RubyGems. I run in the VS code terminal $gem update –system

Then I instal Bundler: gem install bundler but I got an error message

I don’t have write permissions. I googled this error output and I am trying something  I found in stack overflow: sudo gem install bundler. I gave the personal password for my computer and it worked!

The purpose of sudo is to execute the command given to it with root privileges.

Adding Gems to gemfile

I created a new file gemfile and I am adding my gems to it, bundler.

~> is called “Twiddle-Wakka.” '~> 2.0' means any minor version above 2.0,  2.1, 2.2, 2.3 … and 2.9 included would work (including patches); but version 3.0 wouldn’t work because it indicates a new major version.

The second specification '>= 2.0.1'means any version greater than or equal to 2.0.1. Both specifications have to be true, so this gem couldn’t use version 2.0because it’s lower than 2.0.1.

My Gemfile.lock file

I run in the VS code terminal $bundle installAutomatically a file was created in my directory: Gemfile.lock

Reviewing my installed gems

I run in the VS code terminal $gem list

Checking where my Bundler is

I run in the VS code terminal $bundle show [bundler]

Adding Gemfile and Gemfile.lock to my repository

I run in the VS code terminal $git add Gemfile Gemfile.lock.

I could staged the changes in my VS code, they do the same thing that the git add command.

I check my Github repository….and it didn’t work.

Ok! I forgot to push my changes, so I ran: $git push origin master

Done! I got my two new files in my repository.

Now, I want to install Nokogiri

Installing Nokogiri

I run in the VS code terminal $sudo gem install nokogiri

And after the installation was successfully  I add my new gem to the Gemfile

I check if my changes are in Github and…no! They are not! Why? BecauseI forgot to push them.

My work flow in VSC:

Save changes – stage changes – commit changes – push changes

Installing pry

I run in the VS code terminal $sudo gem install pry

And then I add the new gem to the Gemfile

And I don’t forget about my VSC workflow! Save, stage, commit and push.

Installing ‘open-uri’

I was trying to install it and got this error:

I googled it and…

OpenUri is part of Ruby standard library, I just need to require it.

After all this installations I checked my Gemfile.lock and I couldn’t see anything about nokogiri or pry. I run $bundle install and my Gemfile.lock is updated.

Installing ‘colorize’

I run in the VS code terminal $sudo gem install colorize

I add my new gem to the Gemfile.

And run $bundle install to update my Gemfile.lock.

I open my Gemfile and do this with my pry gem:

After installing all my gems I need to require them where I am going to use them.

config/environment.rb

Now, I create a folder config and a file environment.rb inside. In this file I will be loading, requiring, all of my app’s dependencies like my gems.

With this code all the gems that are inside Gemfile are required.

I need to require ‘open-uri’ and ‘colorize’ too in my environment.
