macOs: Crash to OS user login screen

[MattRCole]

PyLNP version: 0.14a
macOs version: 10.14.6

Upon trying to start up the utility, a brief error message is show:

{Traceback (most recent call last):}
{ File "python.lnp/core/launch.py", line 12, in <module> }
{ File "python.lnp/core/lnp.py", line 113, in __init__ }
{ File "python.lnp/core/lnp.py", line 132, in initialize_program }
{ File "python.lnp/core/lnp.py", line 309, }
{SystemExit: 2} 

after which, the program crashes, the user is booted out of their "user session," I suppose, and then needs to log back in.

When trying to run the program from the commandline, the following output is given:

This is the first time I've booted up the program, so no config has changed.

Please let me know if there's any trouble shooting I can help with.

I've been trying to look into this and... it's very strange.

The executable is built on macOS 10.14, and I even tested the builds on a system that doesn't have Python 3, so it's a little surprising this isn't happening for me.

Based on the first error message, it looks like the program can't find Dwarf Fortress. Make sure you've downloaded that separately from http://www.bay12games.com/dwarves/index.html, and also make sure you've moved both PyLNP and Dwarf Fortress out of your Downloads folder (otherwise macOS will hide things and PyLNP can't do anything).

PyLNP needs to be able to find your Dwarf Fortress folder either in the same folder as it, or in some parent folder. For example, if Dwarf Fortress was unpacked to Desktop/df/df_osx, PyLNP needs to be somewhere inside Desktop/df, either directly in that folder, or in some subfolder of Desktop/df.

Having said that, the crash suggests there are other problems, and that's where it gets tricky...

I understand you have not used previous versions of PyLNP on this computer? Could you try downloading and running 0.13b just to make sure it's only happening after the change in build systems?

Also, could you try running the program from source code to make sure it isn't a general Python issue? macOS should come with everything required to start the program - download the source code for 0.14a and unpack it in a folder next to where you currently have the program, then run launch.py from within that folder.
