how to setup ruby on rail in windows

 STEP 1 — Install Linux (WSL)

In PowerShell (Admin) run:

wsl --install

Wait till it finishes.
Then restart your laptop.

---

🧰 STEP 2 — Open Ubuntu

After restart:

• Press Windows key

• Search Ubuntu

• Open it

It will ask:

Enter new UNIX username:
Enter new UNIX password:

Type anything and remember it.

Now you are inside Linux (this is where Rails will run).

---

🧰 STEP 3 — Update Linux

In Ubuntu terminal run:

sudo apt update && sudo apt upgrade -y

---

🧰 STEP 4 — Install Ruby build dependencies

Run:

sudo apt install -y libssl-dev libreadline-dev libyaml-dev libgmp-dev zlib1g-dev rustc build-essential

This replaces all those brew install commands you saw on YouTube.

---

🧰 STEP 5 — Install rbenv (Ruby Version Manager)

sudo apt install rbenv -y

Then:

rbenv init

Close Ubuntu terminal and open it again.

---

🧰 STEP 6 — Install Ruby

rbenv install 3.3.0
rbenv global 3.3.0
ruby -v

If it shows 3.3.x → success ✅

---

🧰 STEP 7 — Install Node.js (Rails needs it)

sudo apt install nodejs npm -y
node -v

---

🧰 STEP 8 — Install Rails

gem install rails
rails -v

---

🧰 STEP 9 — Install PostgreSQL

sudo apt install postgresql postgresql-contrib libpq-dev -y

---

🚀 STEP 10 — Create Your First Rails App

rails new myapp -d postgresql
cd myapp
rails db:create
rails server

Open browser:

http://localhost:3000

🎉 Your Rails app is running!

---

🧠 IMPORTANT RULE

Always use:

Ubuntu terminal
Never use:

Windows CMD or PowerShell for Rails
