Error: Cannot find module './reports/base'

[mateusvahl]

I just installed tap and received the follow errors:

How to reproduce:

1. Install tap and esm: yarn add tap esm

{
  "tap": "14.10.2",
  "esm": "^3.2.25"
}

2. Tap a file: tap my-test-file.js

const tap = require('tap')
tap.pass('this is fine')

Info

• macOS with docker
• node version: 10.16.3

How did I solved:

It seems that adding a reporter solves the problem: tap my-test-file.js --reporter classic

Let me know if you need more information,

I've experienced this issue as well with npm. I determined that having babel.config.js which enables the plugin @babel/plugin-transform-modules-commonjs caused the issue. This would include @babel/preset-env. CC @jaydenseric

Adding ignore: ['**/node_modules/**'] to my babel.config.js worked around this issue. I've posted a PR to import-jsx to fix this issue.

[coreyfarrell]

Not sure what happened, the ignore: ['**/node_modules/**'] was working earlier (I think) but now it's not for me. I've rewritten my babel.config.js to restrict all options within the overrides option:

'use strict';

module.exports = {
	overrides: [{
		test: ['src/**'],
		plugins: [
			'@babel/plugin-transform-modules-commonjs'
		]
	}]
};

This issue should be resolved by tap@14.10.6, can anyone confirm?

[coreyfarrell]

If anyone still experiences the issue with tap 14.10.6+ let us know and this issue can be reopened.

I'm seeing something similar to this with certain modules and Node.js 16. For example, this is from running npm's test suite:

 added 522 packages, and changed 14 packages in 41s
 > npm@7.8.0 test
 > tap
 TAP version 13

Adding a reporter as suggested here resolves the issue.
