How to migrate private scoped packages from .npmrc to .yarnrc.yml?

[Yohanna]

I'm migrating a Yarn v1 project that uses private scoped packages. The project is first setup to create an .npmrc file with the following values:

@<scope_name>:registry:https://private.registry.com/
//private.registry.com//:_password=<base64 encoded authentication token>
//private.registry.com//:[email protected]
//private.registry.com//:[email protected]
//private.registry.com//:always-auth=true

I assumed I have to use npmRegistries and npmScopes in my configuration like so:

nodeLinker: node-modules

npmRegistries:
  //private.registry.com:
    npmAlwaysAuth: true
    npmAuthIdent: "[email protected]:<base64 encoded authentication token>"

npmScopes:
  <scope_name>:
    npmRegistryServer: https://private.registry.com/

yarnPath: .yarn/releases/yarn-berry.cjs

But when I run yarn install after deleting node_modules & yarn.lock, I get this error:

YN0041: │ @<scope_name>/<package_name>@npm:^3.0.5: Invalid authentication (as an unknown user)

How can I migrate .npmrc file properly to Yarn v2?

Yarn: v2.4.1
Node.js: v14.16.0

Thank you :)

Can you try base64'ing your whole ident? Cf this similar thread: #316 (comment)

If it's this, we probably should help detect the problem.

Thanks, @arcanis. That fixed the issue!

Maybe we can update the npmAuthIdent docs to mention the base64 encoding part?

If you run yarn set version 3.0.0-rc.1 you should be getting a more detailed error.

You can use just npmScopes if you want to

npmScopes:
  <scope_name>:
    npmRegistryServer: https://private.registry.com/
    npmAlwaysAuth: true
    npmAuthIdent: "[email protected]:<base64 encoded authentication token>"

Thanks for your reply, @merceyz. Unfortunately using v3.0.0-rc.1 gave me the same error :(

Oh I didn't pay attention to that. Thanks, that's definitely easier.
