Answer 1

I had the same issue the last days. I solved it using this part of my tsconfig.json

"atom": {
    "rewriteTsconfig": true
  },
  "compileOnSave": false,
  "buildOnSave": false,
  "compilerOptions": {
    "experimentalDecorators": true,
    "module": "commonjs",
    "target": "es5",
    "isolatedModules": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "removeComments": false,
    "noImplicitAny": false,
    "sourceMap": true
  },
  "filesGlob": ...

And i also deleted all .js and .js.map files from my working directory. As @KRONWALLED already mentioned, the problem is occuring when you use an IDE which is auto compiling your .ts files. When you are using the atom-typescript package it could be that this is autocompiling your .ts files. That's why you get this error. The important line in the tsconfig.json file is

"compileOnSave": false,

Here we declare that our compiler should not compile the file on save. Only when meteor is running, then the files get compiled with meteor.

I hope this will help you.
