Error when running on Ubuntu

[micheldebree]

I've installed git and yarn, and NodeJS (v8.10), and I've installed RetroPixels via npm, and it doesn't give me any errors during installation. However, when I run it, I get the following errors I can't interpret:

/usr/local/lib/node_modules/retropixels/node_modules/fs-extra/lib/mkdirs/make-dir.js:85 } catch { ^

SyntaxError: Unexpected token { at createScript (vm.js:80:10) at Object.runInThisContext (vm.js:139:10) at Module._compile (module.js:616:28) at Object.Module._extensions..js (module.js:663:10) at Module.load (module.js:565:32) at tryModuleLoad (module.js:505:12) at Function.Module._load (module.js:497:3) at Module.require (module.js:596:17) at require (internal/module.js:11:18) at Object. (/usr/local/lib/node_modules/retropixels/node_modules/fs-extra/lib/mkdirs/index.js:3:44)

Any ideas about what I need to install? I don't recognize any of this stuff.
