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 {

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