Typescript编译时遇到d.ts中的定义冲突：
tsc -p ./ ../../../../../Users/lusin/AppData/Roaming/npm/node_modules/typescript/lib/lib.es2015.iterable.d.ts:41:6 - error TS2300: Duplicate identifier 'IteratorResult'. 41 type IteratorResult<T, TReturn = any> = IteratorYieldResult<T> | IteratorReturnResult<TReturn>; ~~~~~~~~~~~~~~ ../node_modules/@types/node/index.d.ts:77:11 77 interface IteratorResult<T> { } ~~~~~~~~~~~~~~ 'IteratorResult' was also declared here. ../node_modules/@types/node/index.d.ts:77:11 - error TS2300: Duplicate identifier 'IteratorResult'. 77 interface IteratorResult<T> { } ~~~~~~~~~~~~~~ ../../../../../Users/lusin/AppData/Roaming/npm/node_modules/typescript/lib/lib.es2015.iterable.d.ts:41:6 41 type IteratorResult<T, TReturn = any> = IteratorYieldResult<T> | IteratorReturnResult<TReturn>; ~~~~~~~~~~~~~~ 'IteratorResult' was also declared here. Found 2 errors.解决方案是在tsconfig.json的compilerOption中加入下面两项：
"skipLibCheck": true, "allowSyntheticDefaultImports": true完整例子：
{ "compilerOptions": { "module": "commonjs", "target": "es6", "outDir": "out", "rootDir": "src", "sourceMap": true, "skipLibCheck": true, "allowSyntheticDefaultImports": true }, "include": ["src"], "exclude": ["node_modules", ".vscode-test"], }
