Answer 1

The noStrictGenericChecks flag was introduced as part of TypeScript 2.4 . Make sure you have the latest TypeScript version.

You can update your TypeScript version using if you are using globally installed TypeScript for compilation:

npm install -g typescript

Answer 2

I have the same error and have typescript 2.4.0 installed.

npm list typescript

prints typescript@2.4.0

My tsconfig.json file:

{
  "compilerOptions": {
    "noStrictGenericChecks": true,
    "module": "commonjs",
    "target": "es5",
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "noEmitHelpers": true,
    "noEmitOnError": true,
    "lib": [
        "es6",
        "dom",
        "es2015.iterable"
    ],
    "baseUrl": ".",
    "paths": {
        "*": [
            "./node_modules/tns-core-modules/*",
            "./node_modules/*"
        ]
    }
  },
  "exclude": [
    "node_modules",
    "platforms",
    "**/*.aot.ts"
  ]
}

Not enough rep to comment... In the same boat - typescript is 2.4.2 but TypeScript for Microsoft Visual Studio is unable to update past 2.2.2:

I believe this is the source of our pain.
