I'm getting an error on the start mand when using react-native. The file projectName/node_modules/@babel/core/lib/transformation/file/file.js on line 63 is giving the error

constructor(options, {
                     ^

SyntaxError: Unexpected token {

Here is my package.json file

  }
}

I've tried deleting my node_modules file, clearing the npm cache, and reinstalling but to no avail. The problem seems to be in the cli.js file.

I was using the last version of the react-native and nodejs. Unfortunately, I needed to go back to the version 8.11.2. In my case, it is resolved. I removed the node_modules dir.

$ rm -rf node_modules
$ nvm install 8.11.2
$ nvm use 8.11.2
$ npm install [email protected]
