unable to run 'yarn run build'

Question

I'm trying to build my site. It works when I run yarn start

Now I want to build it.

I run yarn run build and i get this error

yarn run build  
yarn run v1.22.17
warning package.json: No license field   
error Command "build" not found.

I have a package.json that contains the same script that allowed previous projects to run.

{
  "name": "bl_site_12_28",
  "version": "0.1.0",
  "private": true,
  "dependencies": {

      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

I tried running yarn run as another post suggested to get a list of possible posts, but i get a similar message above. It seems that yarn is not reading my package.json

@KyleRifqi's helpful comment was all that was needed. I used ls to identify the files in the current directly I was running yarn run build from.

I realized the package.json was not in that directory. I cd into the correct directory and then it worked
