TS1086: An accessor cannot be declared in an ambient context

cloakedninjas commented 4 years ago

Describe the bug Upgraded to 5.3.3 just now and our Angular build is failing with the following:

[ng]
[ng] ERROR in ../../node_modules/@storybook/channels/dist/index.d.ts:25:9 - error TS1086: An accessor cannot be declared in an ambient context.
[ng]
[ng] 25     get hasTransport(): boolean;
[ng]            ~~~~~~~~~~~~

From a quick google, it appears other repos are facing the same issue due to the use of TypeScript 3.7.0 - but Angular is restricted to <3.5.0

I believe the breaking change come from TypeScript directly https://github.com/microsoft/TypeScript/issues/33939 - but until a fix is released, the index.d.ts file will need regenerating with npm i typescript@~3.6.0 (swap ^ for ~)

Try "skipLibCheck": true, inside tsconfig.json eg.

"compilerOptions": {
    "baseUrl": "src",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    **"skipLibCheck": true,**
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  },

Hope it will help you !!

Thank you <3
