TypeError: Bad argument

When I do "markdown-pdf -o test.pdf test.md", I get this.

TypeError: Bad argument
at TypeError (native)

Granted, I used npmbox to build an offline installer for this. But if I'm missing something, I'd really like to know what. Don't deal with node.js and npm stuff everyday. Any clues would be helpful.

I installed markdown-pdf by first installing NPM via the Mac OS package on their website, and then simply running

npm install markdown-pdf

I also get a similar error:

(node:74342) Warning: Possible EventEmitter memory leak detected. 2 end listeners added. Use emitter.setMaxListeners() to increase limit
internal/child_process.js:289
  var err = this._handle.spawn(options);
                         ^

Having trouble reproducing this. This works for me:

$ uname
Linux
$ node --version
v7.10.0
$ cd $(mktemp --dir)
$ npm i markdown-pdf
[ ... npm output ... ]
$ ./node_modules/.bin/markdown-pdf -o test.pdf <(echo '# hi')
[ ... markdown-pdf output ... ]

@mdeforge Are you also on Mac OS?

Hey folks, I met the same trouble on MacOS, and I find this

markdown-pdf requires phantomjs-prebuilt
Medium/phantomjs#533

And it works for me
