RollupJS `resolve failed: Error: Cannot find module 'babel-runtime'`

Question

rollup-error-example

Illustrate a (possible) problem with rollup.

Am I missing something? Here is a project with a minimal configuration to reproduce the "problem" I running into. The problem seems only to be extraneous command-line logging without affecting the bundle itself; i.e. the bundle is created correctly and accurately.

This project displays the output:

$ ./node_modules/.bin/rollup -c rollup.js
node_modules/nan
resolve failed:  { Error: Cannot find module 'babel-runtime'
    at Function.Module._resolveFilename (module.js:472:15)
    at Function.requireRelative.resolve (/Users/jkalis/Pro/QL/WebCore/luxui/rollup-testing/node_modules/require-relative/index.js:30:17)

    at Module._compile (module.js:573:32) code: 'MODULE_NOT_FOUND' } babel-runtime

The command(s) to reproduce this are:

• npm run bundle, or
• ./node_modules/.bin/rollup -c rollup.js

In other projects I have similar issues with additional resolve "failures" that seem not to affect the bundle itself. Is this something that is easily fixable?

I have created a Git repository - https://github.com/kalisjoshua/rollup-error-example - which exhibits this behavior.

What am I missing?

Answer 1

The repo on github that shows how to reproduce the error shows version 1.2.0 of babel-preset-es2015-rollup being used. I found the following on github:

• https://github.com/rollup/rollup/issues/1141
• https://github.com/rollup/babel-preset-es2015-rollup/issues/18

It looks like the babel-preset-es2015-rollup package just needs updated to latest, as after I tried that, the error no longer occured.
