✅ Step 1: Check Python Installation

• First, make sure Python is installed properly.

• Open Command Prompt (cmd) and type:

  python --version
  
  

• If it doesn’t show a version, install Python from the official site: python.org.

• While installing, don’t forget to tick the box “Add Python to PATH” — this is important.

✅ Step 2: Install / Update pip

• Pip is Python’s package manager. Update it to avoid errors:

  python -m pip install --upgrade pip
  
  

✅ Step 3: Install Jupyter Lab

Now try installing Jupyter Lab directly:

pip install jupyterlab

✅ Step 4: Common Fixes if It Still Fails

• Issue: pip not recognized → Means Python/Pip is not added to PATH. Fix it by editing Environment Variables.

• Issue: Installation too slow → Use a faster mirror like:

  pip install jupyterlab -i https://pypi.org/simple
  
  

• Issue: Dependency conflicts → Create a clean environment with Anaconda or venv:

  python -m venv myenv
  myenv\Scripts\activate
  pip install jupyterlab
  
  

✅ Step 5: Launch Jupyter Lab

After installation, just run:

jupyter lab

It will open in your default browser.

💡 Extra Tips

• Many beginners prefer Anaconda Distribution (comes with Jupyter Lab pre-installed and avoids most errors).

• Always keep Python and pip updated.

• If something breaks, uninstall and reinstall:

  pip uninstall jupyterlab
  pip install jupyterlab
  
  

👉 In simple words:
Fixing Jupyter Lab on Windows 11 is usually about three things — Python setup, pip working, and clean installation. Once those are sorted, Jupyter runs smoothly like a personal coding diary.
