Typescript typings - 重复名称Promise /无法找到名字Promise

Question

我正在构建一个客户端/服务器JS应用程序，并且使用Promises有一个大问题。它们要么是未定义的，要么是重复的，它似乎取决于@types包。

npm install --save @types/es6-promise` 

这会给服务器象这样的错误：

cd ../server 
➜ server git:(master) ✗ tsc 
../node_modules/@types/es6-promise/index.d.ts(11,15): error TS2300: Duplicate identifier 'Promise'. 
../node_modules/@types/es6-promise/index.d.ts(42,19): error TS2300: Duplicate identifier 'Promise' 
.../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(4936,11): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5261,11): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5511,13): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5737,11): error TS2300: Duplicate identifier 'Promise'. 
➜ server git:(master) ✗ 

如果我删除该程序包，然后我得到的客户端错误：

tsc 
src/components/GeneralChatAdminInputArea.tsx(100,14): error TS2304: Cannot find name 'Promise'. 
src/components/GeneralChatAdminInputArea.tsx(103,16): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(11,21): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(12,21): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(13,3): error TS2304: Cannot find name 'Promise'. 

有什么出路呢？

我tsconfig.json看起来是这样的：

{ 
    "compilerOptions": { 
     "sourceMap": true, 
     "noImplicitAny": false, 
     "target": "es6", 
     "jsx": "react", 
     "module": "commonjs", 
     "moduleResolution": "node", 
     "isolatedModules": false, 
     "experimentalDecorators": true, 
     "emitDecoratorMetadata": true, 
     "declaration": false, 
     "removeComments": true, 
     "noLib": false, 
     "preserveConstEnums": true, 
     "suppressImplicitAnyIndexErrors": true, 
     "noUnusedLocals": true 
    }, 
    "filesGlob": [ 
     "**/*.ts", 
     "**/*.tsx", 
     "**/*.tsd" 
    ], 
    "compileOnSave": true, 
    "buildOnSave": false, 
    "atom": { 
     "rewriteTsconfig": false 
    } 
} 

这里的显示问题来来去去另一个版本

客户端编译罚款

➜ author git:(402-compile-errors) ✗ cd client 
➜ client git:(402-compile-errors) ✗ tsc 
➜ client git:(402-compile-errors) ✗ cd ../server 

但服务器失败

➜ server git:(402-compile-errors) ✗ tsc 
../node_modules/@types/es6-promise/index.d.ts(11,15): error TS2300: Duplicate identifier 'Promise'. 
../node_modules/@types/es6-promise/index.d.ts(42,19): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(4936,11): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5261,11): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5511,13): error TS2300: Duplicate identifier 'Promise'. 
../../../../../../../usr/local/lib/node_modules/typescript/lib/lib.es6.d.ts(5737,11): error TS2300: Duplicate identifier 'Promise'. 

删除库，现在服务器将编译

➜ server git:(402-compile-errors) ✗ rm -rf ../node_modules/@types/es6-promise 
➜ server git:(402-compile-errors) ✗ tsc          
➜ server git:(402-compile-errors) ✗ cd ../client 

但现在客户端无法

➜ client git:(402-compile-errors) ✗ tsc 
src/components/GeneralChatAdminInputArea.tsx(100,14): error TS2304: Cannot find name 'Promise'. 
src/components/GeneralChatAdminInputArea.tsx(103,16): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(11,21): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(12,21): error TS2304: Cannot find name 'Promise'. 
src/routes/users/index.ts(13,3): error TS2304: Cannot find name 'Promise'. 
➜ client git:(402-compile-errors) ✗ 

所以它似乎是一个catch22

在tsconfig.json缺少lib：

// tsconfig.json 
{ 
    "compilerOptions": { 
    "lib": [ 
     "es2015" 
    ] 
    } 
}
