Error: spawn UNKNOWN

[XavierGeerinck]

Operating System: Windows 10 (last update)
Node Version: v8.1.0
NPM Version: 5.0.2
Command Run: zenbot trade --paper
Problem: When running the command stated above, I get the error shown below. I went to check into the code and only got that error back from the node process. Is there anyone that had this before? Since a quick search online does not return the solution for me.

Output:

PS E:\Projects\zenbot> zenbot trade --paper
fetching pre-roll data:
internal/child_process.js:317
    throw errnoException(err, 'spawn');
    ^

Not sure how interested devs are to fix this, since it's on Windows. I dug up the following about a similar problem:
nodejs/node#3116

I would rather advise to use mac or linux.

You are right indeed, I overlooked the fact that it is executing a shell script so that Windows can not interpret it (no idea how I overlooked that). A solution for windows users is to execute node within the "Bash on Windows" subsystem. Maybe we should add this to the docs somewhere?

[DeviaVir]

@thebillkidy if you are inclined on figuring this out, you could PR an update to the README.md specific for Windows users, that would be great.

[XavierGeerinck]

I got it running now, though it is a workaround rather than a solution. Should I PR the workaround somewhere?

[DeviaVir]

@thebillkidy I think I have an idea for a place for it.

Could you write in a response here the exact steps a Windows user must take to get this working? I will then put it in the right place for you.

Ok, great! So what I did is the following:

Windows

1. Install the "Bash on Windows subsystem" (see https://msdn.microsoft.com/en-us/commandline/wsl/about for more information)

Note: This will change soon, seeing that Microsoft decided to have Ubuntu, Fedora and OpenSUSE available. They will also drop the requirement for requiring dev mode enabled on windows soon.

2. Open the terminal window, your disks will now be mounted under /mnt/*. So for example navigate to your directory (example: cd /mnt/c/zenbot)
3. Install node (`curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -; sudo apt-get install nodejs)
4. Run zenbot as you would otherwise

@DeviaVir Is this enough? :)

May I quote this answer in the FAQ?

[XavierGeerinck]

Yep you may
