Issues trying to run BSK example code

[lostpig23]

Hi everyone, I've been trying to run BSK but I ran into this issue. What does this error mean and how do I solve it?

P.S: I am a beginner student programmer. I sincerely apologize for not knowing some concepts and terms in advance.

Error message:

No module named 'Basilisk.utilities'
Stack trace:

File "C:\Users\Nizam\Downloads\Basilisk\dist3\bsk1.py", line 19, in (Current frame)
from Basilisk.utilities import SimulationBaseClass

Loaded 'runpy'
The program 'python.exe' has exited with code -1 (0xffffffff).

Sounds like it's not recognizing Basilisk when you run that script. Please make sure that you're running that script in the environment where Basilisk is installed.

For a virtual environment and if you're using an IDE to run the script, check that the interpreter you're using is the one inside the environment where you installed Basilisk, not the one your computer defaults to.

For a virtual environment and if you're using the terminal command line to run the script, enter the virtual environment before running the script from the command line.

It's highly recommended that you use a virtual environment to avoid conflicts between different Python installations. Everything should be explained on the Basilisk install instructions.

Hi joaogvcarneiro, thank you for the reply. I have tried running the script in the virtual environment as you suggested and it shows this error. May I know what it means and how do I solve it?

More specifically, I am talking about this error message:

Traceback (most recent call last):
File "scenarioBasicOrbit.py", line 211, in
bskPath = path[0]
TypeError: '_NamespacePath' object is not subscriptable

I don't know what is causing it. It does sound like it's an issue with Python and not Basilisk. Are you sure you installed everything that's needed? It looks like some packages need to be included or something. Also, Basilisk compiling in half a second is very odd. I'm wondering if it's even compiling properly.

Not sure what is happening here either. As João mentioned, I would look into path issue. Your environment does appear to be finding the compiled Basilisk library.
