Visual Studio - Error TS1005 'Unexpected token'

After spending nearly 5 hours scouring the internet for a solution, I am still unable to resolve this persistent issue. The responses I've found so far do not seem to address the specific problem I'm facing.

Although I have upgraded the tsc version to the latest version 3.7.3, the problem persists on visual studio 2017 community.

Upon inspection, the typescript.d.ts file located in node_modules/typescript/lib/ is showing over 3347 errors in visual studio. However, I discovered that not all errors are TS1005; there are also instances of TS2307, TS2304, and others, all pointing to the same file.

Various errors keep occurring on different parts of the page, such as:

Error 1005: 

Error TS1005(TS) '(' expected. Location: Property\node_modules\typescript\lib\typescript.d.ts

Error 2304: 

TS2304 (TS) Cannot find name 'FileReference'. Property\node_modules\typescript\lib\typescript.d.ts 4960

I'm at a loss as to what I might be doing incorrectly here.

Below is an excerpt from my tsconfig.json file:

{
  "compilerOptions": {
    "noImplicitAny": true,
    "noEmitOnError": true,
    "removeComments": false,
    "sourceMap": true,
    "module": "es6",
    "target": "es5",
    "jsx": "react",
    "allowJs": true,
    "outDir": "./wwwroot/_compiled",
    "moduleResolution": "node",
    "typeRoots": [ "node_modules/@types" ]
  },
  "exclude": [
    "wwwroot/dist",
    "node_modules"
  ]
}

Answer №1

Successfully identified the typescript version being utilized by Visual Studio and updated it to the latest version. This resulted in most of the errors disappearing.

Only webpack-related errors remained, but now I can focus on resolving them since I have control over them.
