Duplicate of #1268 and fixed by #1425.

Try a newer version of yarn.

The error message is pretty clear, the name value in your own package.json is invalid. Remove all the invalid characters from it and it will work.

which is the invalid characters ?

{
  "name": "yarn test",
  "version": "1.0.1",
  "description": "yarn & chocolatey",
  "main": "index.js",
  "repository": {
    "url": "https://github.com/xgqfrms-GitHub/webgeeker",
    "type": "git"
  },
  "author": "webgeeker",
  "license": "MIT"
}
