Hi @MaxDaxDax,
I was experiencing the exact same error, with very similar versions:
λ npm version
{ 'pzl-script-editor': '1.0.0',
npm: '6.9.0',
ares: '1.15.0',
brotli: '1.0.7',
cldr: '35.1',
http_parser: '2.8.0',
icu: '64.2',
modules: '64',
napi: '4',
nghttp2: '1.34.0',
node: '10.16.0',
openssl: '1.1.1b',
tz: '2019a',
unicode: '12.1',
uv: '1.28.0',
v8: '6.8.275.32-node.52',
zlib: '1.2.11' }

Using this link as a reference, I ran the following commands from my project directory and got it working.

npm rm -g gulp
npm install -g gulp-cli
npm install --save-dev [email protected]
gulp -v

My gulp version after running these:
λ gulp -v
CLI version: 2.2.0
Local version: 3.9.1

I believe it was necessary to target 3.9.1 based on the entry in the devDependencies section of the package.json folder:
"gulp": "^3.9.1"

Per the node.js semver documentation at this link the caret character indicates

a range of acceptable versions that include all patch and minor versions from the ones specified up to, but not including, the next version. So "^1.2.3" can be approximately expanded as ">=1.2.3 <2.0.0".
