Using pnpm with Lerna

Lerna can be used in a pnpm workspace to get the full benefits of both pnpm and Lerna.

When used in a pnpm workspace, Lerna will:

resolve package locations with pnpm-workspace.yaml (https://pnpm.io/workspaces)
enforce useWorkspaces: true in lerna.json (and ignore packages: in package.json).
block usage of bootstrap, link, and add commands. Instead, you should use pnpm commands directly to manage dependencies (https://pnpm.io/cli/install).
respect the workspace protocol for package dependencies.
- During lerna version, dependencies will be updated as normal, but will preserve the workspace: prefix if it exists.
- If a workspace alias is used, then lerna version will not bump the version of the dependency, since aliases don't specify a version number to bump.

Getting Started

To set up pnpm with Lerna:

If not installed already, install pnpm: https://pnpm.io/installation.
Remove the node_modules/ folder in the root, if it exists. If not already using workspaces, run lerna clean to remove the node_modules/ folder in all packages.
Set "npmClient": "pnpm" in lerna.json.
Create a pnpm-workspace.yaml file in the root of your project. If you are already using npm or yarn workspaces, move the "workspaces" property from package.json to pnpm-workspace.yaml. If you were not already using workspaces, move the "packages" property from lerna.json to pnpm-workspace.yaml. For example:
package.json
```
{
  "workspaces": ["packages/*"]
}
```
and
lerna.json
```
{
  "packages": ["packages/*"]
}
```
become:
pnpm-workspace.yaml
```
packages:
  - "packages/*"
```
(optional) Run pnpm import to generate a pnpm-lock.yaml file from an existing lockfile. See https://pnpm.io/cli/import for supported lockfile sources.
Run pnpm install.
