The statement

 x = $('#msgBox_' + scope.boxId).position().left;

generates an

error TS2304: Cannot find name '$'

although jquery and @types are installed in the node_modules folder.

My tsconfig.json looks like that:

{

  compilerOptions: {

    module: commonjs,

    target: es5,

    sourceMap: true,

    moduleResolution: node,

    declaration: true

  },

  exclude: [

    node_modules

  ]

}

How can I fix that?
