# npm |
|
|
|
|
|
npm is a quick way to get started with n8n on your local machine. You must have [Node.js](https://nodejs.org/en/){:target=_blank .external-link} installed. n8n requires Node.js 18 or above. |

|
## 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){:target=_blank .external-link}. |
|
|
|
|
|
## 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 |
|
|
``` |
|
|
|
|
|

|
|
|
|
|
Start n8n with `--tunnel` by running: |
|
|
|
|
|
```bash |
|
|
n8n start --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){:target=_blank .external-link}. |
