[GO Beginner Basics Chapter 2] Installing Homebrew (Solving Errors) Part 1

"To start programming in GOLANG, it's necessary to download the GOLANG software. Additionally, besides GOLANG, the installation of a few other software programs is required for programming. In Chapter 2, Part 1, we'll download a manager called Homebrew, and in Part 2, we plan to install other necessary software for programming, such as GO, VISUAL STUDIO, GIT Hub, and more.

1. What is Homebrew?

Homebrew is a package manager. Before starting programming, it's necessary to have a manager program like Homebrew to search, install, update, and delete packages or tools required for programming with simple commands. We will install Homebrew and then use it to install GOLANG.

* Understanding Packages

A package is a collection of code, libraries, etc., required to run a program, similar to how various parts like the engine, wheels, and brakes are needed to build a car. An engine, while a complete and essential part on its own, doesn't make a car function by itself. These packages, like engines, wheels, brakes, etc., perform specific functions and are useful independently, but they create greater value as part of a larger system. Just like an engine needs to be combined with other parts to make a car run, packages (like GOLANG, Visual Studio, GIT, etc.) are software components that come together to form a complete software product – the car.

2. Installing Homebrew

 

Homebrew

brew.sh

1. ▶ Visit the Homebrew website at Http://brew.sh.

​

2. ▶ Copy the command /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" from the main screen under "Install Homebrew".

​

3. ▶ Open the Terminal in macOS. Use COMMAND+SHIFT to open the Spotlight search and type Terminal.

​

1. Run Terminal.

2. Paste the copied command from Homebrew and press Enter. Enter your computer's password when prompted.

 

3. Press ENTER

4. Installation is completed.

3. Solving the 'zsh: command not found: brew' Error

 

When faced with the error 'zsh: command not found: brew' after following the guidelines, it can be frustrating, especially for beginners. To resolve this, which prevented the installation of GOLANG:

​

 

1. 'zsh: command not found: brew' 오류가 뜬다

 

​

(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/adellana/.zprofile && (/opt/homebrew/bin/brew shellenv)

2.Copy and paste [the first phrase && the second phrase] as above, and then press ENTER.

​

​

3. Open a new tab in Terminal.

​

​

4. Write brew update and press ENTER.

​

​

5. If it shows 'Already up-to-date', Homebrew installation is complete.

​

​

​

This concludes part 1. In part 2, we will organize brew commands like the 'brew update' practiced earlier and install software.
