require is not defined

Just updated my pyodide from 0.17.0 runnig from a WebWorker to 0.18.1. Since I updated I get the following error when calling loadPyodide from the WebWorker:

Uncaught (in promise) ReferenceError: require is not defined
    at fetchRemotePackage (pyodide.asm.js:14)
    at loadPackage (pyodide.asm.js:14)
    at pyodide.asm.js:14
    at pyodide.asm.js:14
    at loadPyodide (pyodide.js:227)
    at async listener (pyWorker.js:78)

Looks like fetchRemotePackagewas changed in 0.18 to use require('fs') when process is defined as an Object (which it is in a WebWorker).

Yes, indeed thanks for the report. I initially backported emscripten-core/emscripten#11785 to add Node support, but we also should also backport emscripten-core/emscripten#14501 to resolve this. Or better -- update emscripten version to 2.0.25+.

More worrisome though is that WebWorker tests didn't catch this.
