Unfortunately, I have not found a solution to this, but I can give you some notes on what I had tried debugging:

• I was speculating it may have to do with mixing / and \ in those paths on Windows in the modulManifest.js file, which is generated by setup.ts. However, in setup.ts we’re using import { resolve, posix, relative } from "path"; which should choose the proper file delimeter for each platform. I don’t think it is related to this after all.
• looking at the specific error you posted, that seems to be referenced in js-beautify, which is a dependency of mjml-cli:

 grep -R "./lib/beautify"  node_modules
node_modules/js-beautify/js/index.js:    "./lib/beautify",
node_modules/js-beautify/js/index.js:    "./lib/beautify-css",
node_modules/js-beautify/js/index.js:    "./lib/beautify-html"

It may have to do with the way that the .mailing folder includes its node_modules – there is no directory .mailing/node_modules, instead we rely on module resolution traversing up to the root directory node_modules and finding those libraries correctly. I might give a look in your project root node_modules directory to see if you have a js-beautify directory and it has all the right stuff in it:

ls node_modules/js-beautify/js/lib/*
node_modules/js-beautify/js/lib/beautifier.js		node_modules/js-beautify/js/lib/beautify-html.js
node_modules/js-beautify/js/lib/beautifier.min.js	node_modules/js-beautify/js/lib/beautify.js
node_modules/js-beautify/js/lib/beautify-css.js		node_modules/js-beautify/js/lib/cli.js

node_modules/js-beautify/js/lib/unpackers:
javascriptobfuscator_unpacker.js	p_a_c_k_e_r_unpacker.js
myobfuscate_unpacker.js			urlencode_unpacker.js

Sorry I don’t know a concrete next step here, but hopefully that helps your debugging?

current semi fix is to use wsl for development
