Why lerna version assuming all packages changed?

Question

I use GitHub Action to publish my own package, and I made some changes in @mosiure/pkgA.

However,I found that lerna version will handle all my packages, even though I never made change in those packages.

Did I type the wrong lerna version command? Anyone can help me?

Part of my yaml file:

jobs:
  publish-monorepo:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Use Node.js
        uses: actions/setup-node@v4
        with:
          node-version: 20
          registry-url: https://registry.npmjs.org/

      - name: Global Install pnpm
        run: npm i -g pnpm

      - name: Install Related Package
        run: pnpm install

      - name: Release And Tagged Version
        run: lerna version --conventional-commits --preid beta --yes

      - name: Publish Packages
        run: lerna publish from-git --yes
        env:
          NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}

Expecting: lerna version won`t handle the unchanged package.

Actullay:

Run lerna version --conventional-commits --yes

Answer 1

You are using "fixed versioning" and want to use "independent versioning". See here. Fixed will have one single version number for all packages and release all packages if a single package or more are changed. Independent versioning will release individual versioned packages.

Check your configuration.
