Overview

The Ionic command-line interface ([CLI](/docs/faq/glossary#cli)) is your go-to tool for developing Ionic apps.

Installation

The Ionic CLI can be installed globally with npm:

$ npm install -g ionic

Help

The Ionic CLI ships with command documentation that is accessible with the --help flag.

$ ionic <command> --help

Architecture

The Ionic CLI is built with TypeScript and Node.js. It supports Node 6+, but the latest Node LTS is always recommended. Follow development on the open source Github repository.

Troubleshooting

To troubleshoot issues with the Ionic CLI, the following may be useful:

  • Make sure the latest version of the Ionic CLI is installed. Update with npm install -g ionic.
  • Make sure the latest Node LTS is installed. See Node & npm environment setup.
  • The --verbose flag prints debugging messages, which may narrow down the issue.
  • Connection issues may be due to improperly configured proxy settings. See Using a Proxy to configure request proxying.
  • The global Ionic CLI configuration directory is ~/.ionic on all platforms. It can safely be deleted and the Ionic CLI will repopulate it, but all configuration (including user sessions) will be lost.
