javascript - Typescript-typningar - Duplicerat namn Promise/Kan inte hitta namnet Promise
Jag bygger en klient-/server-JS-app och har ett stort problem med att använda Promises. De är antingen odefinierade eller duplicerade och det verkar bero på @types-paketet.
npm install --save @types/es6-promise`
detta kommer att ge serverfel som detta:
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) ✗
Om jag tar bort det paketet får jag klientfel:
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'.
Vad är vägen ut ur detta?
Min tsconfig.json ser ut så här:
{
"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
}
}
här är en annan version som visar problemet kommer och går
klienten kompilerar utan problem
➜ author git:(402-compile-errors) ✗ cd client
➜ client git:(402-compile-errors) ✗ tsc
➜ client git:(402-compile-errors) ✗ cd ../server
men servern misslyckas
➜ 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'.
ta bort biblioteket och nu kommer servern att kompilera
➜ 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
men nu misslyckas klienten
➜ 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) ✗
Så det verkar som ett moment 22
Svar #1
Saknar lib i din tsconfig.json:
// tsconfig.json
{
"compilerOptions": {
"lib": [
"es2015"
]
}
}
