TypeError: def.isBoolean is not a function

[ronyad]

Hey Im using node 6.3.0
When I ran the following command

$ node RecordingSourceOnly.js -t 5

where RecordingSourceOnly.js is

const commandLineArgs = require('command-line-args')

const optionDefinitions = [
    { name: 'verbose', alias: 'v', type: Boolean },
    { name: 'src', type: String, multiple: true, defaultOption: true },
    { name: 'timeout', alias: 't', type: Number }
]
const options = commandLineArgs(optionDefinitions)

I got

    if (def.isBoolean()) {
            ^

i can't reproduce your issue - when i run the same code it works fine.. please try deleting then re-installing all npm modules.

Ok I found the problem
I'm using also q-io/fs module , therefore the bug reproduce if commandLineArgs is called after qio defined, i.e.

const qio = require('q-io/fs');
const options = commandLineArgs(optionDefinitions) //throw error

But If i changed the the order, i.e.

const options = commandLineArgs(optionDefinitions)
const qio = require('q-io/fs');

Then It works.
I case its matter, i'm using OS x

confirmed - thanks for letting me know what caused the issue.. I recommend you no longer use q-io until this issue is fixed.

consider this lightweight fs library which uses promises: https://github.com/75lb/fs-then-native
