The "file" argument must be of type string. Received type object

Hi,

When I run markdown-pdf README.md I get the following error:

    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

Can anyone suggest any solution?

I get the same with node 11.11.0. Reinstall without --ignore-scripts option and worked fine.

better to do:

sudo npm uninstall -g markdown-pdf
sudo npm install -g markdown-pdf --unsafe-perm
