title: Skipping Automatic Dependency Installation
url: /docs/deployments/concepts/settings/skip-dependency-installation/
---
By default, the deployment executor will attempt to install dependencies for your project by using the default dependency manager for the language (i.e. `npm` for nodejs or `virtualenv` for python). However, there may be scenarios where you may want to have more control over the dependency installation step (e.g. you are using `yarn` and/or a different version of `node` than the one that is installed by default).

This is enabled by skipping the default dependency installation step (under Advanced Settings in the UI), and setting a few pre-run commands and environment variables.
