Visual studio 2017 | TS2304: Cannot find name 'unknown'
I tried to load some new type definition files into my cordova/typescript project.
Now i receive the following error:
TS2304: Cannot find name 'unknown'.
In those definition files, the unknown type (keyword) isn't painted in blue like 'any' or 'string' etc.
Manually installing typescript extension also didn't solve it.
tsconfig.json:
{
"compileOnSave": true,
"compilerOptions": {
"inlineSources": true,
"module": "system",
"noEmitOnError": true,
"noImplicitAny": false,
"out": "www/scripts/appBundle.js",
"preserveConstEnums": true,
"removeComments": true,
"sourceMap": true,
"target": "es2015"
},
"files": [ ... ]
}
VS2017 info:

Kinda sounds like you're on an older version of Typescript, so the compiler doesn't recognize theunknownkeyword which was introduced in TS 3.0. Can you check your Typescript version like so
