@zakdances Hmm. Please provide a simple example that produces the error.

@johnsoftek I couldn't re-create this error. Sorry for wasting your time!

@zakdances @johnsoftek

Do we know what resolved this issue?

I'm trying to create a JSPM plugin using Pug. I'm running into this same issue (see screenshot below).

@coderfin Are you trying to include uglify a Javascript file?

coderfin commented 7 years ago

@johnsoftek Yes, it's part of pug/jade

johnsoftek commented 7 years ago

@coderfin pug/jade is written for node.js, so it uses modules and objects that exist in node.js such as fs and the process object. So you need to avoid code that uses those features. For example, plugin-jade replaces the built-in include to bypass the use of fs.

I assume that you are using include name-of-javascript-file.uglify. You could extend the include replacement to recognise .uglify and invoke a browser friendly uglifyjs - or process as plain js.
