Typescript compiler: Cannot find name 'Map'

Question

I have Electron + Angular app. I would like to use Typescript for Electron, so I have main.ts file and want to compile it to main.js using 'tsc main.ts'. However, I get the following error:

node_modules/@types/selenium-webdriver/remote.d.ts:139:29 - error TS2304: Cannot find name 'Map'.

Still main.js is generated and can be used when i run electron without tsc command. However, I would like it run by one script without any error.

My tsconfig.json contains:

{
 "compileOnSave": false,
 "compilerOptions": {
  "baseUrl": "./",
  "outDir": "./dist/out-tsc",
  "sourceMap": true,
  "declaration": false,
  "module": "es2015",
  "moduleResolution": "node",
  "emitDecoratorMetadata": true,
  "experimentalDecorators": true,
  "target": "es5",
  "typeRoots": [
    "node_modules/@types"
   ],
  "lib": [
   "es2017",
   "dom"
  ]
 }
}

I've already tried various combinations of target and lib configuration (e.g. es6) but with no success.

Can anybody please help? Many thanks!

Your target and lib properties are fine. It's probably something to do with typeRoots. Perhaps the library depends on a version of the nodejs types or something and it is installed in a subdirectory due to multiple versions — Aluan Haddad

When you run tsc main.ts, your tsconfig.json file is not being used. Instead run tsc -p . or simply tsc, and if necessary, restrict the input files to the compilation using the files, include, and exclude options in tsconfig.json.

Many thanks Matt, solved by changing command to just tsc and by adding include and exclude sections before compilerOptions in tsconfig.json

For some reason, when I added the include and exclude sections as above, I still got errors:

"../node_modules/@types/selenium-webdriver/http.d.ts:24:14 - error TS2583: Cannot find name 'Map'. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later"

The errors stopped when I ran: npm i @types/node

I would love to know why (:

I had this issue after upgrading from Angular 6 to Angular 8. Turns out the upgrade script updates the Typescript version, but the @types/node package was outdated in my package.json (and apparently, not compatible anymore with the new Typescript version). Updating it did the trick !
