Jupyter Notebook and JupyterLab are essential tools for working with Python and data analysis. When attempting to perform Jupyter-related instructions in your command prompt or terminal, you may get a frustrating error. 

'jupyter' is not recognized as an internal or external command,operable program or batch file.

This error can occur if your Jupyter installation is outdated or not complete. The error message is as followed:

This error message might be troubling, so let’s take a closer look at this error and learn how we can fix it.

What is the Error?

The error message “Jupyter is not recognised as an internal or external command” indicates that the Jupyter executable cannot be found by the operating system. This problem frequently arises when attempting to run Jupyter commands from the command prompt or terminal.
The ‘jupyter’ executable is not recognized as a valid command because it’s not in the system’s PATH environment variable. 

Causes of the Error

The error “jupyter is not recognized as an internal or external command, operable program or batch file” occurs due to following reasons:

1. Outdated or Missing Installation

An outdated or incomplete Jupyter installation is a common source of this problem. If your Jupyter installation is outdated or incomplete, the system will be unable to locate the files required to perform the command, resulting in the error.

2. PATH Environment Variable Issue

The PATH environment variable is essential for command execution. It includes a list of folders through which the system searches when you run a command. If the directory containing the Jupyter executable is not in the PATH, the system will not know where to look when you run the jupyter command.

Solutions to Fix the Error

We can take the following measures to resolve the error.

1. Solutions to Fix the Error in Windows

Following solutions can be used to resolve the error when occured on windows.

a) Install Jupyter using pip Application

If you already have jupyter but it is not working properly then reinstall jupyter on your command system. For uninstalling previous jupyter, steps are as followed:

  1. Click on the “Start” button located in the Windows taskbar.
  2. From the menu that appears, select “Settings.”
  3. Inside the Settings window, you’ll find a range of options. Locate and select “Apps” from the menu tiles. From there you can uninstall your jupyter notebook.
    Now to install jupyter notebook on your system you can use pip application.

Open your Command Prompt:
Go to start menu and search command prompt or directly press Windows+R then write cmd and click enter. Now, run the following code on your command prompt to install jupyter:

python -m pip install jupyter

b) Add Jupyter to the PATH

Step 1: Locate your jupyter installation directory

  1. Open your command prompt on window.
  2. If you are not sure about your jupyter installation directory, you can use the 'which' command to locate it.
    which jupyter
    This code will display complete path to jupyter executable.

Step 2: Add Jupyter to PATH

  1. Right-click on the Start button and select System.
