package.json 中没有许可证

Question

I cloned a project from (...) / I am working on a node project.

When I run my code with the yarn I do the following command:

yarn start

However, it shows:

yarn run v1.22.10

warning ..\package.json: No license field
error Command "start" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

I have tried uninstalling, removing, and updating yarn and npm, but I still have the same error.

I also tried to manually update package.json but I still have the same error.

Answer 1

If package.json in the root folder of your project contains "license" field and you're still getting this warning. That means there is another package.json that is this warning for.

As you can see the path of the JSON file is in the warning:

warning ..\package.json: No license field

That double dots ..\ saying that the package.json file is one folder up where you are running your command. It could be OUTSIDE the project folder you're working on.

So if you go one folder up you will find another package.json file. Either add "license" field into it or simply delete the file if you do not need it.
