Typescript, confusing "duplicate identifier" error message -

can me understand why getting , many more errors of kind? link github key code snippets below. think have basic misunderstanding of how dependency , "include" chaining works. thanks!

csvproc(master)> tsc node_modules/typescript/bin/lib.core.d.ts(83,5): error ts2300: duplicate identifier 'configurable'. node_modules/typescript/bin/lib.core.d.ts(84,5): error ts2300: duplicate identifier 'enumerable'. node_modules/typescript/bin/lib.core.d.ts(85,5): error ts2300: duplicate identifier 'value'. node_modules/typescript/bin/lib.core.d.ts(86,5): error ts2300: duplicate identifier 'writable'. 

all code can found here.

my tsconfig.json:

{     "compileroptions": {         "module": "commonjs",         "noimplicitany": false,         "outdir": "built/",         "sourcemap": true,         "target": "es5"     } } 

my tsd.json:

{   "version": "v4",   "repo": "borisyankov/definitelytyped",   "ref": "master",   "path": "typings",   "bundle": "typings/tsd.d.ts",   "installed": {     "node/node-0.10.d.ts": {       "commit": "6387999eb899d0ba02d37dd8697647718caca230"     },     "should/should.d.ts": {       "commit": "e1182d56ccb192379eade6055d9ba3fb6a0bacc4"     }   } } 

my tsd.d.ts:

{   "version": "v4",   "repo": "borisyankov/definitelytyped",   "ref": "master",   "path": "typings",   "bundle": "typings/tsd.d.ts",   "installed": {     "node/node-0.10.d.ts": {       "commit": "6387999eb899d0ba02d37dd8697647718caca230"     },     "should/should.d.ts": {       "commit": "e1182d56ccb192379eade6055d9ba3fb6a0bacc4"     }   } } 

this because of combination of 2 things:

• tsconfig not having files section. http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

if no "files" property present in tsconfig.json, compiler defaults including files in containing directory , subdirectories. when "files" property specified, files included.

• including typescript npm dependency : node_modules/typescript/ means of typescript gets included .... there implicitly included lib.d.ts in project anyways (http://basarat.gitbooks.io/typescript/content/docs/types/lib.d.ts.html) , conflicting 1 ships npm version of typescript.

fix

either list files explicitly or have atom-typescript generate key : https://github.com/typestrong/atom-typescript/blob/master/docs/tsconfig.md#filesglob
