[BUG] npm 7.10 does not recursively install modules in local filesystem

[andreash]

Current Behavior:

I have

    +- main_project  
    |  +-package.json
    +- packages
       +- package1
          +-package.json

In package1 as cwd I do npm install express and then rm -rf node_modules and rm package-lock.json. Then, in main_project as cwd I do npm install. The express module does not get installed in package1 with npm 7.10. If I use npm 6.14.12 everything is fine and npm installs recursively and express and its dependencies show up in the node_modules subdirectory of package1.

Expected Behavior:

I expect npm 7.10 to behave the same way as npm 6.14.12

Steps To Reproduce:

See steps above and zip attached - pretty simple.

Environment:

• OS: Ubuntu 20.04
• Node: v14.16.1 with npm 7.10 and v12.22.1 with npm 6.14.12
• npm: 7.10 / 6.14.12

@andreash Downgrade npm to 6x or use yarn instead.

[andreash]

Yeah, that's what I am doing (user npm 6.x). Yarn doesn't work for me for other reasons. But I still see this as a bug in npm 7.

Seems duplicate of #2339 (and #3028): npm 7 issue with transient dependencies for local path deps (referenced through file:)

v7 doesn't install package's dependencies that are outside of the root (ie. any package defined as ../... isn't going to get it's dependencies reified) - this is indeed a duplicate
