Cannot Run 'pip install' Command on MacOS zshrc

Installing Xcode

The first step in configuring a new MacBook Pro for software development is to install Xcode. Xcode is a software development environment (IDE) for macOS, and it includes everything you need to create great apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. To install Xcode, follow these steps:

1. Open the App Store on your Mac.
2. Search for Xcode.
3. Click the "Get" button next to Xcode.
4. Enter your Apple ID and password when prompted.
5. Wait for Xcode to download and install.

Once Xcode is installed, you can open it and start exploring its features. Note that Xcode is a large application, and it may take some time to download and install.

Installing iTerm2, Oh My Zsh, and Tmux

The next step is to install iTerm2, Oh My Zsh, and Tmux. These tools are essential for any software developer, as they provide a more powerful terminal experience than the default Terminal app. Here's how to install them:

iTerm2

1. Download iTerm2 from https://iterm2.com/downloads.html.
2. Double-click the downloaded file to open it.
3. Drag the iTerm2 icon into the Applications folder.
4. Open iTerm2 from the Applications folder.

Oh My Zsh

1. Open iTerm2.
2. Type the following command and press Enter: sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
3. Wait for Oh My Zsh to install.

Tmux

1. Type the following command and press Enter: brew install tmux
2. Wait for Tmux to install.

Once these tools are installed, you can start using them. Oh My Zsh will automatically be set as your default shell, and you can start a new Tmux session by typing tmux in iTerm2.

Setting Aliases for pip, python, pip3, and python3

The next step is to set aliases for pip, python, pip3, and python3. This will make it easier to use these tools, as you won't have to remember the exact command to use. Here's how to set the aliases:

1. Open the .zshrc file in your home directory.
2. Add the following lines to the file:
   alias pip=pip3 alias python=python3

3. Save the .zshrc file.
4. Close and reopen iTerm2 to apply the changes.

Now you can use pip and python to run pip3 and python3, respectively.
