TypeScript build error TS5023

Question

I am trying to compile TypeScript & NodeJS an getting this error any help?

tsc --version => Version 2.7.2

error TS5023: Unknown compiler option 'lib'.
error TS5023: Unknown compiler option 'strict'.
error TS5023: Unknown compiler option 'esModuleInterop'.
The terminal process terminated with exit code: 1

Updated, added tsconfig.json

{
  "compilerOptions": {
    "target": "ES5",                          
    "module": "commonjs",                    
    "lib": ["es2015"],                            

    "sourceMap": true,                     
    "strict": true,                           
    "esModuleInterop": true, 

    "mapRoot": "./map"                      
  }
}

Doing tsc on the command line would probably just give you the globally installed version. Is your local typescript version updated? — kingdaro

I have found my mistake forget to call local version of TypeScript ./node_modules/.bin/tsc --init

What do you mean by call local version of TypeScript. Do you have an example?

You mean you weren't using the local version of Typescript in the project... ?

I had a similar issue where I was using ntsc npm package as a part of an example. Changing to use the correct tsc command fixed half my issues.

npm install --save-dev [email protected] fixed it at my side.

What fixed for my was installing global the typescript via npm package manager:

npm install -g typescript

And then the tsc compiler was available:

e.g.: tsc -p src/server/ -w
