yarn link error No registered package found called

Question

I'm developing an npm package for custom React Hooks. And using yarn for package management. The custom hooks are in the src directory, and to prevent posting the wrong code to npm, I've created a new demo folder locally at the same level as src.

To test my hooks code locally, I bundled my hooks and used yarn link to link it in my demo project smoothly as if I installed it from the registry. And next I run yarn start in my demo folder to run my test project. But it reminded me Invalid Hook Call Warning in the Chrome console.

After reading this article I knew that it is because I used duplicate React, So I tried to this command: yarn link ../node_modules/react but it just told me

error No registered package found called "../node_modules/react".
info Visit https://yarnpkg.com/en/docs/cli/link for documentation about this command.

But when I tried to use npm link ../node_modules/react there is no error reported. I can start my test project smoothly.

But here comes the problem: I am using yarn for package management and it has its own lock file yarn.lock. If I want to run my test project, I had to run npm link ../node_modules/react, this step will generate a npm lock file which is a Redundancy for me.

So how can I use yarn link ../node_modules/react instead of npm link ../node_modules/react to link a same version React?

I will assume this question is still relevant because I stumbled upon it while looking for the answer myself. I managed to figure it out eventually.

The yarn link docs state the following:

This command is run in the package folder you’d like to consume.

In order to create a link for React, you have to cd ../node_modules/react and then yarn link while in that directory. You can then use yarn link react from the other side to consume the linked package.

For the record, it doesn't look like it matters which side you create the link from (the library or the consumer) as long as the other side makes use of it.
