Installation

Several options are available for installation of Arduino CLI. Instructions for each are provided below:

Install via Homebrew (macOS/Linux)¶

The Arduino CLI is available as a Homebrew formula since version 0.5.0:

brew update
brew install arduino-cli

Command line completion¶

Command line completion files are already bundled in the homebrew installation.

Use the install script¶

The script requires sh, which is always available on Linux and macOS. sh is not available by default on Windows,
though it is available as part of Git for Windows (Git Bash). If you don’t have sh
available, use the “Download” installation option.

This script will install the latest version of Arduino CLI to $PWD/bin:

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh

If you want to target a different directory, for example ~/local/bin, set the BINDIR environment variable like this:

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | BINDIR=~/local/bin sh

If you would like to use the arduino-cli command from any location, install Arduino CLI to a directory already in your
PATH or add the Arduino CLI installation path to your PATH
environment variable.

If you want to download a specific Arduino CLI version, for example 0.9.0 or nightly-latest, pass the version number
as a parameter like this:

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh -s 0.9.0

Arduino CLI checks for new releases every 24 hours. If you don’t like this behaviour you can disable it by setting the
updater.enable_notification config or the
env var ARDUINO_UPDATER_ENABLE_NOTIFICATION to false.

Pre-built binaries for all the supported platforms are available for download from the links below.

If you would like to use the arduino-cli command from any location, extract the downloaded file to a directory already
in your PATH or add the Arduino CLI installation path to your
PATH environment variable.

Latest release¶

Deprecation notice: links in the form
http://downloads.arduino.cc/arduino-cli/arduino-cli-latest-<platform>.tar.bz2 won’t be further updated. That URL
will provide the version 0.3.7-alpha.preview, regardless of further releases.

Previous versions¶

These are available from the “Assets” sections on the releases page.

Nightly builds¶

These builds are generated every day at 01:00 GMT from the master branch and should be considered unstable. In order
to get the latest nightly build available for the supported platform, use the following links:

These links return a 302: Found response, redirecting to latest generated builds by replacing latest with the
latest available build date, using the format YYYYMMDD (i.e for 2019-08-06 latest is replaced with 20190806 )

Checksums for the nightly builds are available at
https://downloads.arduino.cc/arduino-cli/nightly/nightly-<DATE>-checksums.txt

Build from source¶

If you’re familiar with Golang or if you want to contribute to the project, you will probably build Arduino CLI locally
with your Go toolchain. See the “How to contribute” page for instructions.
