Complete Tutorial for Installing Jupyter Notebook on Mac System

# Complete Tutorial for Installing Jupyter Notebook on Mac

## Preparation Work

Before we start the installation of Jupyter Notebook, some preparations are necessary to ensure a smooth installation process.

### Check System Version and Configuration
To install Jupyter Notebook on a Mac, we first need to ensure that the system version and configuration meet the requirements. Please follow these steps to check:
- System version: Make sure your Mac system version is MacOS X 10.7 (Lion) or higher.
- Memory: It is recommended to have at least 2GB of memory for Jupyter Notebook to run smoothly.
- Disk space: Ensure that your hard drive has sufficient available space to install the required software and store data in Jupyter Notebook.

### Install Homebrew Package Manager
Homebrew is a commonly used package manager on Macs, and we can use it to install software and tools. Here are the steps to install Homebrew:
1. Open the Terminal application.
2. In the Terminal, enter the following command and press Enter to install Homebrew:

    /bin/bash -c "$(curl -fsSL ***"

3. Follow the steps prompted in the Terminal to complete the installation of Homebrew.

Once the installation is complete, we can proceed to install Python and Jupyter Notebook. The next section will provide detailed instructions on how to perform these installation steps on a Mac system.

# 2. Install Python

In this section, we will learn how to install Python on a Mac system and set up the corresponding environment variables.

### Use Homebrew to Install Python 3
First, we need to use the Homebrew package manager to install Python 3. Here are the specific steps for the installation process:

1. Open the Terminal and run the following command to update Homebrew:

     brew update

2. Then, use the following command to install Python 3:

     brew install python3

3. You can verify the successful installation of Python 3 by running the command:

     python3 --version

### Set Up Python Environment Variables
After installing Python 3, we need to set up the corresponding environment variables so that the system can correctly recognize and invoke Python. Here are the steps for setting environment variables:

1. Open the Terminal and edit the `~/.bash_profile` or `~/.zshrc` file, adding the following content:

     export PATH="/usr/local/opt/python/libexec/bin:$PATH"

2. Save the file and run the following command to activate the environment variables:

     source ~/.bash_profile

3. Finally, you can verify that Python can be invoked normally by running the command:

     python3 -c "print('Python installed successfully')"

With these steps, we have successfully installed Python 3 and set up the corresponding environment variables, paving the way for the subsequent installation of Jupyter Notebook. Next, we will continue to install Jupyter Notebook.

# 3. Install Jupyter Notebook

Installing Jupyter Notebook is an important step in using Python for data analysis and visualization on a Mac system. Below, we will provide detailed instructions on how to install and start Jupyter Notebook.

### Use pip to Install Jupyter Notebook
First, we need to use the pip tool to install Jupyter Notebook. Execute the following command in the Terminal:

pip3 install jupyter

Once the installation is complete, you can verify the successful installation of Jupyter Notebook by running the command:

jupyter notebook --version

### Start the Jupyter Notebook Server
1. In the Terminal, start the Jupyter Notebook server with the following command:

    jupyter notebook
