`lerna publish from-package` failed about lerna HOT 2 OPEN

I try to run lerna publish prerelase in other test repo, and the packages be successful published!

from lerna.

If others encounter the same situation as mine, here is my solution.

What happend?

The demo file structure in my monorepo:

├── lerna.json
├── nx.json
├── package.json
├── packages
│   ├── base
│   ├── is-even
│   └── is-odd
└── yarn.lock

I only want to publish two packages, packages/is-even and packages/is-odd. The packages/base directory contains utility functions and is not intended to be published as a package. Therefore, I have set packages/base as private:

// packages/base/package.json
{
  "private": true,
  "description": "Base utils"
}

Another necessary content occur the issue which should know is "workspaces" in my root package.json:

// package.json
{
  "name": "root",
  "private": true,
  "workspaces": [
    "packages/*"
  ],
  "dependencies": {},
  "devDependencies": {
    "lerna": "^8.0.0",
    "nx": "17.2.8"
  }
}

Deep dive

Well, I thought lerna would filter and exclude packages/base first because they are private. Indeed, lerna does do that, but before excluding them, lerna also reads private packages to obtain metadata information. This is because packages/base matches the definition in the root package.json under workspaces: ["packages/*"]. During the metadata reading process, lerna reads the "name" property of sub-packages, and since packages/base does not define a "name," it leads to the occurrence of this issue.

Solutions

• option 1: add "name" property in packages/base, or
• option 2: update workspaces: ["packages/is-*"] in root package.json;

After the update, lerna publish from-package works properly! 😄
