Heads up! If the command line isn't your thing, learn more about GUIs for Less.
Install with npm
npm install less -gThe -g option installs the lessc command available globally. For a specific version (or tag) you can add @VERSION after our package name, e.g. npm install less@2.7.1 -g.
Alternatively, if you don't want to use the compiler globally, you may be after
npm i less --save-devThis will install the latest official version of lessc in your project folder, also adding it to the devDependencies in your project's package.json.
Periodically, as new functionality is being developed, lessc builds will be published to npm, tagged as beta. These builds will not be published as a @latest official release, and will typically have beta in the version (use lessc -v to get current version).
Since patch releases are non-breaking we will publish patch releases immediately and alpha/beta/candidate versions will be published as minor or major version upgrades (we endeavour since 1.4.0 to follow semantic versioning).
The binary included in this repository, bin/lessc works with Node.js on *nix, OS X and Windows.
Usage: lessc [option option=parameter ...] <source> [destination]
