--- contentType: tutorial --- # npm npm is a quick way to get started with n8n on your local machine. You must have [Node.js](https://nodejs.org/en/) installed. n8n requires a Node.js version between 20.19 and 24.x, inclusive. --8<-- "_snippets/self-hosting/installation/latest-next-version.md" ## Try n8n with npx You can try n8n without installing it using npx. From the terminal, run: ```bash npx n8n ``` This command will download everything that's needed to start n8n. You can then access n8n and start building workflows by opening [http://localhost:5678](http://localhost:5678). ## Install globally with npm To install n8n globally, use npm: ```bash npm install n8n -g ``` To install or update to a specific version of n8n use the `@` syntax to specify the version. For example: ```bash npm install -g n8n@0.126.1 ``` To install `next`: ```bash npm install -g n8n@next ``` After the installation, start n8n by running: ```bash n8n # or n8n start ``` ### Next steps Try out n8n using the [Quickstarts](/try-it-out/index.md). ## Updating To update your n8n instance to the `latest` version, run: ```bash npm update -g n8n ``` To install the `next` version: ```bash npm install -g n8n@next ``` --8<-- "_snippets/self-hosting/installation/tunnel.md" /// note | Docker required The tunnel uses cloudflared, which runs as a Docker container. Make sure [Docker](https://docs.docker.com/get-docker/) is installed on your machine, even when running n8n via npm. /// For npm installations, use the **services only** approach. Start cloudflared as a standalone service, then run n8n locally: ```bash # Terminal 1: Start the cloudflared tunnel service pnpm --filter n8n-containers services --services cloudflared # Terminal 2: Start n8n locally pnpm dev ``` The `services` command starts cloudflared, fetches the public tunnel URL, and writes a `.env` file to `packages/cli/bin/.env` with `WEBHOOK_URL` and `N8N_PROXY_HOPS=1`. n8n picks up this `.env` automatically on startup. Clean up when done: ```bash pnpm --filter n8n-containers services:clean ``` For the full stack approach (n8n and cloudflared both in containers), refer to the [Docker tunnel setup](/hosting/installation/docker.md#n8n-with-tunnel). ## Reverting an upgrade Install the older version that you want to go back to. If the upgrade involved a database migration: 1. Check the feature documentation and release notes to see if there are any manual changes you need to make. 1. Run `n8n db:revert` on your current version to roll back the database. If you want to revert more than one database migration, you need to repeat this process. ## Windows troubleshooting If you are experiencing issues running n8n on Windows, make sure your Node.js environment is correctly set up. Follow Microsoft's guide to [Install NodeJS on Windows](https://learn.microsoft.com/en-us/windows/dev-environment/javascript/nodejs-on-windows).
