Support nodejs experimental-modules

[jehon]

Are you creating an issue in the correct repository?

The "bug" (unwanted feature) is at jasmine.js#89.5

Expected Behavior

We should be able to use the "ecmascript" experimental modules of nodejs (https://nodejs.org/dist/latest-v11.x/docs/api/esm.html),

Current Behavior

we receive an error:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /mnt/c/Users/jhn/src/kiosk/tests/server/basic-test.mjs

at Jasmine.execute (/mnt/c/Users/jhn/src/kiosk/node_modules/jasmine/lib/jasmine.js:257:8)

Possible Solution

Jasmine should use "import" instead of "require" when loading esm modules. But that is not that easy, since "import" is asynchronous, while require is synchronous.

Suite that reproduces the behavior (for bugs)

• Create a .jsm file (can be any test, even a simple one)
  launch nearly as usual:

node --experimental-modules node_modules/.bin/jasmine

Context

This is blocking to use jasmine in this new (experimental) context.

Your Environment

• Version used: 3.3.1
• Environment name and version (e.g. Chrome 39, node.js 5.4): nodejs v10.15.1
• Operating System and version (desktop or mobile): ubuntu
• Link to your project:

After looking, I think it is part of the jasmine-npm package. I opened a bug there:
jasmine/jasmine-npm#150

[jehon]

Reopened to include the management of the stacktrace in core

[frank-dspeed]

where is the pr?

[frank-dspeed]

#1662

[damianobarbati]

Is there any workaround actually to use jasmine with node v14.3 and ESM imports?

jasmine/jasmine-npm#150 (comment) :

jasmine --require=esm

or

  "requires": [
    "esm"
  ],

Closing this issues as the relevant issue on jasmine-npm has been resolved and merged into main there to be included in the next release.
