Ionic 2 RC 0 Build Tsconfig.json Error


I go to start a new ionic 2 project.

When I open my project in atom IDE, typescript gives me this error:
tsconfig.json: The project files contain invalid options: unknown option: lib.

This is what my tsconfig.json looks like:

  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
    "module": "es2015",
    "moduleResolution": "node",
    "target": "es5"
  "exclude": [
  "compileOnSave": false,
  "atom": {
    "rewriteTsconfig": false

This would not be a big issue, but this error blocks me from seeing other errors that come up as I move over my project to the rc. Any ideas on how to get rid of this typescript error?

Thanks in advance

Chances are you do not have TS2.0 installed. Please install

npm install -g typescript

Thanks for your help - all I had to do was update my atom typescript package.
