Ways of Installing Ruby. We have several tools on each major platform to install Ruby: On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM). On macOS machines, you can use third-party tools (rbenv and RVM). Click 'Mac OS X' to download for Mac. Install from the downloaded file postgresql-9.4.0-1-osx.dmg just like any other Mac installers. Follow through the installation wizard with the default options. Installing Stack Builder is optional and can be omitted.

Applications

There are a good many applications that will get you up and running with Sass in a few minutes for Mac, Windows, and Linux. You can download most of the applications for free but a few of them are paid apps (and totally worth it).

• CodeKit (Paid) Mac
• Ghostlab (Paid) Mac Windows
• Hammer (Paid) Mac
• LiveReload (Paid, Open Source) Mac Windows
• Prepros (Paid) Mac Windows Linux
• Scout-App (Free, Open Source) Windows Linux Mac

Command Line

When you install Sass on the command line, you'll be able to run the sass executable to compile .sass and .scss files to .css files. For example:

First install Sass using one of the options below, then run sass --version to be sure it installed correctly. If it did, this will include 1.27.0. You can also run sass --help for more information about the command-line interface.

Unzip RAR files on your Mac from the Context menu. With WinZip for Mac 2.0 or later, you can right-click (or press CTRL and click) your saved RAR files and use the Context Menu to unzip them. Click on Services at the bottom of the Context menu, then choose Unzip. Buy WinZip for Mac. Rar zip for mac. IZip is a free powerful archiving utility designed specifically for Mac. Easily manage ZIP and RAR files directly from the OS X Finder. Open and securely share ZIP, encrypted ZIP and RAR plus other compressed file formats.

Install Gem For Mac Mojave

Once it's all set up, go and play. If you're brand new to Sass we've set up some resources to help you learn pretty darn quick.

Install Anywhere (Standalone)

You can install Sass on Windows, Mac, or Linux by downloading the package for your operating system from GitHub and adding it to your PATH. That’s all—there are no external dependencies and nothing else you need to install.

Install Anywhere (npm)

If you use Node.js, you can also install Sass using npm by running

However, please note that this will install the pure JavaScript implementation of Sass, which runs somewhat slower than the other options listed here. But it has the same interface, so it’ll be easy to swap in another implementation later if you need a bit more speed!

Install on Mac OS X or Linux (Homebrew)

If you use the Homebrew package manager for Mac OS X or Linux, you can install Dart Sass by running

• Current Releases:
• Dart Sass1.27.0
• LibSass3.6.4
• Ruby Sass ⚰

A brief note on how to install and setup PostgreSQL for Ruby on Rails on Mac OS.

Install Gem For Mac High Sierra

• Install PostgreSQL
• Install pgAdmin

Prerequisites

This note assumes that Ruby on Rails has already been properly installed and the purpose is to replace the default DB engine SQLite with PostgreSQL.

Install PostgreSQL

As shown in the official Postgres download instructions here, there are few ways of installing PostgreSQL on Mac OS. Homebrew or Postgres.app are the common ones that often recommeded by other Mac users.

However, as I also use Linux and Windows machines for development, installing PostgreSQL using grapichal installer from EnterpriseDB would be a more widely used solution that keeps everything consistent across all my environment. This grapichal installer provides an easy and straightforward wizard to get Postgres installed with few simple clicks.

Download

1. Go to https://www.enterprisedb.com/software-downloads-postgres
2. Select a version. (For example, the latest installer version is Version 9.4.0).
3. Click 'Mac OS X' to download for Mac.

Install

1. Install from the downloaded file postgresql-9.4.0-1-osx.dmg just like any other Mac installers.
2. Follow through the installation wizard with the default options.
3. Installing Stack Builder is optional and can be omitted.

Add to PATH

1. Locate where PostgreSQL's binary is. By default, it should be /Library/PostgreSQL/9.4/bin/psql, where 9.4 is the PostgreSQL version number. Otherwise, use the following find command to find the path.

   sudo find / -name 'psql'

2. Open ~/.bash_profile with following command.

   

   open ~/.bash_profile

3. Add the following line to .bash_profile using the PostgreSQL's binary path.

   PATH=$PATH:/Library/PostgreSQL/9.4/bin

Install pgAdmin

Install Gem Bundler Mac

Install Gem Mysql2 Mac

pgAdmin is the most popular and feature rich Open Source administration and development platform for PostgreSQL. It helps users manage PostgreSQL databases through graphical interfaces.

Install

1. Download Mac OS dmg installer from https://www.pgadmin.org/download/macos4.php.
2. Install it (e.g. the latest is pgadmin3-1.20.0.dmg).

Connect to server

1. Open up pgAdmin III from the applications.
2. The local DB should be already shown up in Obeject Browser -> Server Groups -> Servers -> PostgreSQL 9.4 (localhost:5432). If not, manually add a server pointing to localhost:5432 or the port number specified when installing PostgreSQL.

Install pg gem

Install Gem For Mac Catalina

1. Open up a terminal window

2. Find out where pg_config is using the command below. By default, it should be /Library/PostgreSQL/9.4/bin/pg_config for PostgreSQL 9.4.

   sudo find / -name 'pg_config'

3. Install the gem with pg-config path explicitly specified.

   gem install pg -- --with-pg-config=/Library/PostgreSQL/9.4/bin/pg_config

Install Gem For Mac Os

Update Ruby on Rails project

1. Update 'Gemfile'. Replace gem 'sqlite3' with gem 'pg'.

2. Run bundle install.

3. Open config/database.yml file and update it like the following:

Original (for SQLite):

Install Gem Mac Brew

New (For PostgreSQL):

Create DB using PostgreSQL

rake db:create && rake db:migrate
