After I upgraded to Typescript 2.9.1 (from 2.8) I got compile error said 

node_modules/typescript/lib/lib.es2017.full.d.ts:33:11 - error TS2300: Duplicate identifier 'Account'.

This is never happened when I was using typescript 2.7 and 2.8.

Environment:

  • MacOS 10.13.5
  • Node.js v9.11.1
  • NPM: 6.1.0
  • Typescript 2.9.1 (in my project's node_modules folder and no global typescript)
// tsconfig.json

Just a workaround, I'm using skipLibCheck: true to bypass the type check in lib files so there's no error. But I still don't know why this happen in 2.9.1.
