node-js examples not compiling

To try and run the examples I do the following with a freshly cloned repo:

cd examples/examples-nodejs
npm i
tsc faceDetection.ts

I get the following error:

node_modules/@types/webgl2/index.d.ts:582:13 - error TS2403: Subsequent variable declarations must have the same type.  Variable 'WebGL2RenderingContext' must be of type '{ new (): WebGL2RenderingContext; prototype: WebGL2RenderingContext; readonly ACTIVE_ATTRIBUTES: number; readonly ACTIVE_TEXTURE: number; ... 556 more ...; readonly WAIT_FAILED: number; }', but here has type '{ new (): WebGL2RenderingContext; prototype: WebGL2RenderingContext; readonly ACTIVE_ATTRIBUTES: number; readonly ACTIVE_TEXTURE: number; ... 557 more ...; readonly MAX_CLIENT_WAIT_TIMEOUT_WEBGL: number; }'.

582 declare var WebGL2RenderingContext: {
                ~~~~~~~~~~~~~~~~~~~~~~

  ../../../../../../usr/lib/node_modules/typescript/lib/lib.dom.d.ts:16485:13
    16485 declare var WebGL2RenderingContext: {
                      ~~~~~~~~~~~~~~~~~~~~~~
    'WebGL2RenderingContext' was also declared here.


Found 1 error.

I have the following: tsc --version: 3.7.2 node --version: 12.13.0

I have tried adding skipLibCheck: true to tsconfig.json but it did not do any difference.

Do you have any idea why it is not working for node?

The solution was to first run

npm i && npm run-script build

in the root directory before trying to run the examples.

This command compile. tsc --skipLibCheck faceDetection.ts But then it doesn’t work
