But if you ever try to run a command like git and get an error that it isn’t installed, or some other prompt about the command line developer tools, you’ll need to install them.
## What is the Command Line Tools Package?
The Command Line Tools Package is a small self-contained package available for download separately from Xcode and that allows you to do command line development in macOS. It consists of the macOS SDK and command-line tools such as Clang, which are installed in the `/Library/Developer/CommandLineTools` directory.
## Should I install Xcode or the Command Line Tools Package?
This depends. If you’re planning to do development on the Mac, you probably want to install the full version of Xcode from the App Store, which includes everything in the Command Line Tools Package. However, if you just need the basic command line tools, you can install the Command Line Tools Package independently of Xcode.
## How to Install the Command Line Tools Package
#### 1. Open the Terminal Application
The Terminal application can be found in the `/Applications/Utilities/` directory.
#### 2. Install the Command Line Tools
Run the following command in the terminal:
“`bash
xcode-select –install
“`
This will trigger a popup from the system letting you start the installation process.
> **Note:** If you’re on macOS 10.9 or later, you can also install the command line tools directly from the command line without any user interaction by running:
> “`bash
> xcode-select –install
> “`
#### 3. Agree to the License Agreement
After the download is complete, you may be prompted to agree to the license agreement. You can do this by running the following command:
“`bash
> sudo xcodebuild -license
“`
#### 4. Verify the Installation
After installation is complete, verify the tools have been installed by running:
“`bash
> git –version
“`
or
“`bash
> clang –version
“`
If these commands return version information, the tools have been successfully installed.
#### 5. Optional: Switch Between Xcode and Command Line Tools
If you have both Xcode and the Command Line Tools installed, you can switch between them using:
“`bash
> sudo xcode-select –switch /Library/Developer/CommandLineTools
“`
or to switch back to Xcode:
“`bash
> sudo xcode-select –switch /Applications/Xcode.app/Contents/Developer
“`
