lerna init

Create a new Lerna repo or upgrade an existing repo to the current version of Lerna

Install lerna for access to the lerna CLI.

Usage

$ lerna init

Create a new Lerna repo or upgrade an existing repo to the current version of Lerna.

Lerna assumes the repo has already been initialized with git init.

When run, this command will:

1. Add lerna as a devDependency in package.json if it doesn't already exist.
2. Create a lerna.json config file to store the version number.
3. Generate a .gitignore file if one doesn't already exist.

Example output on a new git repo:

$ lerna init
lerna info version v2.0.0
lerna info Updating package.json
lerna info Creating lerna.json
lerna success Initialized Lerna files

Options

--independent

$ lerna init --independent

This flag tells Lerna to use independent versioning mode.

--exact

$ lerna init --exact

By default, lerna init will use a caret range when adding or updating the local version of lerna, just like npm install --save-dev lerna.

To retain the lerna 1.x behavior of "exact" comparison, pass this flag. It will configure lerna.json to enforce exact match for all subsequent executions.
