I am sorry, but I still think this issue applies. Or at least additional descriptions in documentation would be nice…

If I am pointing to a local package bar in a package foo like:

dependencies: {
    "bar": "file:../bar"
}

and I run lerna bootstrap it will not install bar in node_modules of foo.

However, if I run lerna bootstrap --scope foo it will install the local dependency as expected.

If I use the lerna add bar --scope=foo to add it, it will add the dependency like this(as if it was installed remotely from the npm registry):

dependencies: {
   "bar": "^1.0.0"
}

and it will work as expected.

As someone already pointed out, I really find a lack of documentation here - it was really hard to figure out how to do it properly and know that Lerna was actually symlinking and using the local package.

I’d gladly contribute and add a PR for update documentation, but I am still not entirely sure I get how it works so…

@luponZ I can confirm your solution works, however, I would like to know why. From my understanding it should also work with --scope. Maybe this should be reopened because it is a bug?
