Solution

I managed to work around this problem by relocating the workspace to the same drive (from D: to C: in my case).

Before:


   D:\work\myproj\com.work.Test\src\index.js → build\appBundle.js...
    [!] (plugin Rollup Core) Error: Could not load /Users/myuser/AppData/Roaming/npm/node_modules/wpe-lightning-cli/src/alias/wpe-lightning.js (imported by D:\work\myproj\com.work.Test\node_modules\wpe-lightning-sdk\src\Lightning\index.js): ENOENT: no such file or directory, open 'D:\Users\myuser\AppData\Roaming\npm\node_modules\wpe-lightning-cli\src\alias\wpe-lightning.js'

After:


    C:\work\proj\com.work.Test>lng build
    √ Testing internet connection..
    √ Verifying if your installation of Lightning-CLI is up to date.
    √ Removing "C:\work\proj\com.work.Test\build" folder
    √ Ensuring "C:\work\proj\com.work.Test\build" folder exists
    √ Copying support files to "C:\work\proj\com.work.Test\build"
    √ Copying static assets to "C:\work\proj\com.work.Test\build"
    √ Copying settings.json to "C:\work\proj\com.work.Test\build"
    √ Copying metadata.json to "C:\work\proj\com.work.Test\build"
    √ Building ES6 appBundle and saving to "C:\work\proj\com.work.Test\build"

Conclusion: Looks like the path was invalid ... src/alias/ does not exist.
