nohoist with workspaces still hoisting

Question

Inside my Monorepo I have one packages in which I want all the dependencies inside its node_modules.

But whatever I do, it's node_modules remains empty.

So, for the purpose of my question I was able to reproduce the issue with the following setup

/
 package.json
 lerna.json
 node_modules
 packages/
          A/
            node_modules
            package.json
            index.ts
          B/
            node_modules
            package.json
            index.ts

I've created a repo for this!

Main package.json

{
  "name": "A-B-test",
  "private": true,
  "workspaces": {
    "packages": ["packages/*"],
    "nohoist": [ "**/B" ]
  },
  ...
  "devDependencies": {
    "lerna": "^3.13.4"
  }
}

B/package.json looks like

{
  "name": "@scaljeri/B",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {
    "angular": "^1.7.8"
  },
  "devDependencies": {
    "browserify": "^16.2.3",
    "typescript": "^3.5.2"
  }
}

Now when I run yarn in the root of the project, all dependencies are installed in the root node_modules.

yarn version: 1.16.0 node: 12.4.0

Any suggestions what might be the problem?

Answer 1

In my experience, it has been necessary to doubly specify each package in the following manner:

{
  "nohoist": [
    "**/B",
    "**/B/**",
    "**/C",
    "**/C/**"
  ]
}

In addition, I have found it necessary to delete all existing node_modules folders after modifying the nohoist settings. So, if your projects are in packages, and you are in your project directory, you can delete all of those node_modules folders like this:

# delete node_modules on linux
rm -rf ./packages/*/node_modules
rm -rf ./node_modules

# install again
yarn install --check-files
