"exclude" property of tsconfig.json is not being respected

Question

I am working with the excellent Express/Node/Typescript example code found here. It transpiles the .ts code with the following command from run.sh:

./node_modules/.bin/tsc --sourcemap --module commonjs ./bin/www.ts

This works as advertised, but I would prefer to use a tsconfig.json file and tsc -p . However, when I run that command I get a raft of TS2300: Duplicate identifier 'foo' errorswhen tsc(erroneously?) tries to walk the ./node_modules and ./typings directories. Below is the tsconfig.json I am using:

{
  "compilerOptions": {
    "target": "ES5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules",
    "typings"
  ]
}

Any ideas? I am using tsc 1.7.3 FWIW.

In a similar vein I was having issues with node_modules exclusion.

Here's a heavy handed solution, that ignores all *.d.ts files.

I added to compilerOptions:

"compilerOptions": {
    "skipLibCheck": true,
    ...
 }
