Fail to compile wasm locally

[wangtz]

This site is great starting point for learning wasm. However it doesn't seem to work locally with "Download" button.

I tried gulp --require ts-node/register --gulpfile ./build.ts and got the following errors:

[08:59:33] Requiring external module ts-node/register ReferenceError: primordials is not defined at fs.js:35:5 at req_ (/usr/local/google/home/wangtz/projects/emcc/v3/node_modules/natives/index.js:143:24) at Object.req [as require] (/usr/local/google/home/wangtz/projects/emcc/v3/node_modules/natives/index.js:55:10) at Object.

Here is my tsconfig.json file (I copied it from this repo).

{ "compilerOptions": { "outDir": "./dist/", "sourceMap": true, "noImplicitAny": true, "skipLibCheck": true, // "module": "esnext", "moduleResolution": "node", "target": "esnext", "lib": ["dom", "esnext", "es2017.object"], "jsx": "react", "declaration": true, "removeComments": false }, "include": [ "./src/*/", "node_modules/monaco-editor/monaco.d.ts" ], "exclude": [ "./templates/*/" ] }

Any help will be appreciated. Thanks!

Upgrading Gulp to 4 and rewriting build.ts, or Downgrading Node to v10 brings me successful build in my environment.
