Windows command line error messages are confusing, but here's the solution

[zackees]

On Windows 10:

This command:

docker2exe-windows-amd64.exe --name fastled

Produces the following help file instructing me to add in --image

NAME:
   docker2exe - create an executable from a docker image

USAGE:
   docker2exe-windows-amd64.exe [global options] command [command options] [arguments...]

COMMANDS:
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --name value               name of your executable
   --image value              name of your docker image
   --embed                    embed a docker image in the binary (default: false)
   --workdir value, -w value  mount the user's current directory in the image
   --env value, -e value      whitelist environment variables
   --volume value, -v value   bind mount a volume
   --output value             directory to output
   --target value, -t value   platforms and architectures to target

   --help, -h                 show help (default: false)
Required flag "image" not set

But when I do so:

C:\Users\niteris\dev\fastled-wasm>docker2exe-windows-amd64.exe --name fastled --image fastled
go mod init github.com/DESKTOP-I3718DO\Zach Vorhies/fastled
go: 'go mod init' accepts at most one argument
make: *** [go.mod] Error 1
exit status 2

I get this error that makes no sense to me. But I'm not a go programmer.

I was able to work through the problem with AI.

If anyone else stumbles on this same error, it's because you didn't put enough arguments into the command.

Seems like an easy fix to the developer to warn on unexpected number of arguments.. Anyway, here's a full command that's now working for me.

docker2exe-windows-amd64.exe --name fastled --image niteris/fastled-wasm --module "github.com/niteris/fastled-wasm" --embed

Okay, it didn't complete using cmd.exe, complaining about a missing /usr/bin/env

I worked around it by dropping down into git bash and running that same command.
