LoadError: UndefVarError: active_repl not defined with ReplMaker

Hello all! I am having some trouble with ReplMaker.jl, and getting this error in return:

LoadError: UndefVarError: active_repl not defined

I wrote a little module I was intending to put " using UnixRepl" into my startup.jl file. Here is the code for my entire module so far:

using ReplMaker
Base.atreplinit() do repl
    repl.interface = REPL.setup_interface(repl)
    repl.interface.modes[1].prompt =
                 Pkg.REPLMode.promptf()[1:end-6] * " julia> "
end
function parse_command(s)
    dims = split(s, " ")
    command = dims[1]
    if length(dims) != 1
        param = dims[2]
    end
    if command == "cd"
        cd(param)
    elseif command == "ls"
        readdir()
    elseif command == "pwd"
        pwd()
    else
        try
            run(Cmd(s))
        catch
            println("Could not determine command")
        end
    end
end
initrepl(parse_command,
    prompt_text="bash> ",
    prompt_color = :yellow,
    start_key='[',
    mode_name="bash")

This is what I get when I include it from the original project files after activating with Pkg:

bash> ls

bash> pwd

However, anytime it is either
A. loaded into startup.jl
B. ran in startup.jl
C. imported simply using using
I get that same return, here is a stacktrace:

emmett@y700:~/dev$ julia
  Activating new environment at `~/dev/UnixRepl.jl/Project.toml`
ERROR: LoadError: LoadError: UndefVarError: active_repl not defined

And that is with this startup.jl file:

using Pkg; Pkg.activate("UnixRepl.jl")
include("UnixRepl.jl/src/UnixRepl.jl")

I am uncertain, what is this issue? Thank you for the help.
