# Install or update the Snyk CLI You can install or update the [Snyk CLI](https://docs.snyk.io/developer-tools/snyk-cli) using the methods explained on this page. After you install the Snyk CLI, you must [authenticate](https://docs.snyk.io/developer-tools/snyk-cli/commands/auth). Then you can [get started](https://docs.snyk.io/developer-tools/snyk-cli/getting-started-with-the-snyk-cli) testing and fixing your vulnerabilities, beginning with testing your installation. {% hint style="info" %} Snyk recommends always keeping your CLI installation updated to the latest version. You can check which version of the Snyk CLI you have installed by running `snyk --version`. {% endhint %} For information about installing the CLI for an IDE, see the [IDE documentation](https://docs.snyk.io/developer-tools/snyk-ide-plugins-and-extensions). You can also install the CLI in a CI/CD environment. For details, see the [CI/CD documentation](https://docs.snyk.io/developer-tools/snyk-ci-cd-integrations). ## Install with standalone executables {% hint style="info" %} When you use this method, you must keep the Snyk CLI up to date manually. {% endhint %} Use [GitHub Releases](https://github.com/snyk/snyk/releases) to download a standalone executable (macOS, Linux, Windows) of Snyk CLI for your platform. Snyk also provides these standalone executables on the Snyk Content Delivery Network (CDN). See the latest `release.json` [file](https://downloads.snyk.io/cli/stable/release.json) for the download links. Examples for a specific version or platform follow: * /release.json * * For example, to download and run the latest Snyk CLI on macOS, you could run: ```bash curl --compressed https://downloads.snyk.io/cli/stable/snyk-macos -o snyk chmod +x ./snyk mv ./snyk /usr/local/bin/ ``` You can also use these direct links to download the executables: | OS\Architecture | amd64 | arm64 | | --------------- | ----------------------------------------------------------------- | --------------------------------------------------------------------------- | | macOS | [snyk-macos](https://downloads.snyk.io/cli/stable/snyk-macos) | [snyk-macos-arm64](https://downloads.snyk.io/cli/stable/snyk-macos-arm64) | | Linux | [snyk-linux](https://downloads.snyk.io/cli/stable/snyk-linux) | [snyk-linux-arm64](https://downloads.snyk.io/cli/stable/snyk-linux-arm64) | | Alpine | [snyk-alpine](https://downloads.snyk.io/cli/stable/snyk-alpine) | [snyk-alpine-arm64](https://downloads.snyk.io/cli/stable/snyk-alpine-arm64) | | Windows | [snyk-win.exe](https://downloads.snyk.io/cli/stable/snyk-win.exe) | - | You can rename the files for example snyk-win.exe to snyk.exe so you can run snyk commands as documented, for example, `snyk test`. {% hint style="info" %} To use CLI releases before version 1.1230.0 on an Apple M1 or M2 machine (darwin/arm64), see [Using CLI releases before version 1.1230.0 on an Apple M1 or M2 machine](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/using-cli-releases-before-version-1.1230.0-on-an-apple-m1-or-m2-machine). To use the CLI with Alpine Linux, see [Prerequisites for CLI and Jenkins plugin on Alpine Linux operating system](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/prerequisites-for-cli-and-jenkins-plugin-on-alpine-linux-operating-system). For more information see [verify CLI standalone binaries](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/verifying-cli-standalone-binaries). {% endhint %} ## Install with Homebrew (macOS, Linux) Install Snyk CLI from [Snyk's tap](https://github.com/snyk/homebrew-tap) with [Homebrew](https://brew.sh) by running the following. The tap is updated daily with the latest Snyk CLI release. ```bash brew tap snyk/tap brew install snyk ``` {% hint style="warning" %} For Apple M1 or M2 (darwin/arm64), see: [Using CLI releases before version 1.1230.0 on an Apple M1 or M2 machine](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/using-cli-releases-before-version-1.1230.0-on-an-apple-m1-or-m2-machine). {% endhint %} ## Install with Scoop (Windows) Install Snyk CLI from [Snyk's bucket](https://github.com/snyk/scoop-snyk) with [Scoop](https://scoop.sh) by running the following. The bucket is updated daily with the latest Snyk CLI release. ``` scoop bucket add snyk https://github.com/snyk/scoop-snyk scoop install snyk ``` ## Install the Snyk CLI with npm or Yarn Before installing the Snyk CLI using npm, be sure you have installed the **prerequisites**: * Install the latest version of npm in your local environment, using Node.js version 12 or later. For information on how to update Node.js see [Install or upgrade to version of Node.js required for Snyk CLI](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/install-or-upgrade-to-version-of-node.js-required-for-snyk-cli). * To run Snyk on Alpine Linux, first install libstdc++.\ For more information see [Prerequisites for CLI and Jenkins plugin on Alpine Linux operating system](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/prerequisites-for-cli-and-jenkins-plugin-on-alpine-linux-operating-system). Then follow these **steps to install with npm or Yarn**: [Snyk CLI is available as an npm package](https://www.npmjs.com/package/snyk). If you have Node.js installed locally, you can **install** the npm package by running `npm install snyk -g`. If you are using Yarn, **install** by running `yarn global add snyk`. For additional information see [Installing Snyk CLI as a binary using npm](https://docs.snyk.io/developer-tools/snyk-cli/install-or-update-the-snyk-cli/installing-snyk-cli-as-a-binary-using-npm). ## Snyk CLI in a Docker image Snyk CLI can also be run from a Docker image. Snyk offers multiple Docker images under [snyk/snyk on Docker Hub](https://hub.docker.com/r/snyk/snyk). See [snyk/snyk-images on GitHub](https://github.com/snyk/snyk-images) for details. These images wrap the Snyk CLI and, depending on the Tag, come with relevant tooling for different projects. An example follows for scanning a Gradle project with `snyk/snyk`: ```bash docker run -it \ -e "SNYK_TOKEN=" \ -v ":/project" \ -v "/home/user/.gradle:/home/node/.gradle" \ snyk/snyk:gradle:6.4 test --org=my-org-name ``` This is an example for scanning a Maven project with `snyk/snyk`: ``` docker run --rm \ -e SNYK_TOKEN= \ -v :/app \ -v /settings.xml:/root/.m2/settings.xml \ snyk/snyk:maven snyk monitor \ --all-projects=true \ --maven-aggregate-project ``` ## Windows Subsystem for Linux (WSL) Snyk CLI does not natively support WSL. It may be possible to install and use the CLI in a WSL environment, but compatibility is not guaranteed. By extension, some Snyk integrations, such as IDE extensions and CI/CD plugins that rely on the CLI, also do not natively support WSL.
