2. Install Nitro by opening a terminal and running

   bash <(curl -sLS http://installer.getnitro.sh)
   

macOS via Brew

You can alternatively install Nitro using the Homebrew (opens new window) package manager if you have it installed.

1. Install Docker Desktop:

   brew install homebrew/cask/docker
   

2. Install Nitro:

   brew install craftcms/nitro/nitro

macOS Manual Installation

If you run into issues with either install method, you can manually install Nitro instead by adding the appropriate binary to your system:

1. Install Docker Desktop Docker Desktop (opens new window) 3.0.0 or higher.
2. Visit Nitro’s GitHub Releases (opens new window) page and download the archive for your system.
3. Extract the release archive and make nitro executable with chmod +x ./nitro.
4. Move the binary into your path with sudo mv ./nitro /usr/local/bin.

   If the /usr/local/bin/ directory doesn’t exist, create it with
   sudo mkdir -p -m 775 /usr/local/bin && sudo chown $USER: /usr/local/bin.

5. Allow Nitro to be trusted by opening your terminal and either
   • Running nitro, choosing Cancel for the security prompt, and visiting System Preferences → Security and Privacy → General to choose Allow Anyway next to the warning about nitro being blocked.
   • Running the following to strip the quarantine flag macOS adds automatically:
     xattr -dr com.apple.quarantine /usr/local/bin/nitro
6. Run nitro init and follow the prompts to initialize the Nitro environment.

Installing Nitro for Linux

1. Install Docker Engine for your distro.
   • Ubuntu (opens new window)
   • Fedora (opens new window)
   • Debian (opens new window)
   • CentOS (opens new window)
   • binaries (opens new window)
2. Open a terminal and run bash <(curl -sLS http://installer.getnitro.sh).

Make sure you follow instructions (opens new window) to add your user to the docker group so you don’t need to run Docker using sudo.

Linux Manual Installation

1. Visit Nitro’s GitHub Releases (opens new window) page and use the nitro_linux_x86_64.tar.gz bundle.
2. Extract the release archive and make the nitro executable with chmod +x ./nitro.
3. If /usr/local/bin does not exist for you, create it with sudo mkdir -p -m 775 /usr/local/bin && sudo chown $USER: /usr/local/bin.
4. Move the binary into your path with sudo mv ./nitro /usr/local/bin.
5. Run nitro init and follow the prompts to initialize the Nitro environment.

Installing Nitro for Windows

Nitro 2 runs on Windows 10 Home or Pro and requires build 19042 or higher with WSL2.

Read Developing using Nitro and WSL2.

1. Install Docker Desktop (opens new window) 3.0.0 or higher, making sure Install required Windows components for WSL 2 is checked.
2. Install WSL2 (opens new window).
3. Install the WSL2 Linux kernel update package (opens new window).
4. In Windows PowerShell, set the default WSL to version 2 using wsl --set-default-version 2.
5. Install a WSL2 compatible distro from the Microsoft Store. We recommend Ubuntu 20 (opens new window).
6. In Docker Desktop, go to Settings → General and make sure Use the WSL 2 based engine is checked.
7. In Docker Desktop, go to Settings → Resources → WSL Integration and make sure WSL is enabled for the distro you installed.

   If your distro isn’t listed after choosing Refresh or restarting Docker Desktop, make sure it’s installed and upgraded to WSL v2. If running wsl -l -v lists your distro with a 1 next to it, upgrade with wsl --set-version [distro name] 2.

8. Open the WSL2 terminal. If you installed Ubuntu, for example, it will be listed as “Ubuntu” in the Start Menu.
9. Verify Docker is running inside the distro by running docker ps. If Docker is not running you’ll get an error message, otherwise you should see a table for containers even though there aren’t any running yet:

   oli@ubuntu:~$ docker ps
   CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
   oli@ubuntu:~$
   

10. From the WSL terminal, run bash <(curl -sLS http://installer.getnitro.sh).

Windows Manual Installation

If you run into issues with the shell script installer, you can manually install Nitro:

1. Visit Nitro’s GitHub Releases (opens new window) page and use the nitro_linux_x86_64.tar.gz inside your WSL2 instance.
2. Extract the release archive and make the nitro executable with chmod +x ./nitro.
3. If /usr/local/bin does not exist for you, create it with sudo mkdir -p -m 775 /usr/local/bin && sudo chown $USER: /usr/local/bin.
4. Move the binary into your path with sudo mv ./nitro /usr/local/bin.
5. Run nitro init and follow the prompts to initialize the Nitro environment.

Uninstalling Nitro
