[BUG] on npm install npm does not run the prepublish scripts in workspace packages.

[michalczaplinski]

Current Behavior:

Repo has workspace packages like:

├── package.json
└── packages
    └── a
        └── package.json

Workspaces are defined like:

// root package.json
"workspaces": [
  "packages/*"
]

Package a has a prepublish script:

"scripts": {
  "prepublish": "touch a-prepublish"
},

then when running npm install at root, the prepublish script does not run.

Expected Behavior:

The prepublish script should run on npm install in all of the packages that are specified as workspace packages.

Steps To Reproduce:

https://github.com/michalczaplinski/npm-bug-repro

run npm install at root of the repo.

You can verify that the file a-prepublish file was not created in the package a.

Environment:

> npm -v
7.9.0
> node -v
v15.11.0

I think the prepublish script might be going/gone away, but it's currently the only way to make package build scripts actually work with workspaces.

See #3034 for a similar issue I was experiencing.

npm install does not currently support workspaces. It is being worked on right now, and script ordering will be something that is handled correctly when it does ship.

You can follow the progress of adding workspace support to all of arborist's reify commands in the cli here
