Simply install by running npm install -g nexe, and try to run nexe my-node-app.js gives me this error message:

/usr/local/lib/node_modules/nexe/node_modules/fuse-box/Utils.js:68
function uglify(contents, { es6 = false, ...opts } = {}) {

Oh Shoot! Looks like fuse-box introduced a > node 8 requirement.

Any update on this?

I've been trying to work out how I can install Node 8 separately, and use this purely for NEXE to get round the problem.

Unfortunately I have to keep Node 7 as my default instance as I use Nodeclipse, which is not compliant with Node 8.

Being a bit of a newbie, I haven't worked that bit out yet, so any pointers would be helpful!!

Have you tried nvm? [https://davidwalsh.name/nvm]. Looks like it makes it easy to switch between Node versions.

This should work for anyone hitting this issue until it can be fixed:
