AttributeError: 'dict' object has no attribute '__dict__'

Expected Behavior:

Running pros make template in a freshly-cloned pros directory builds the template project.

Actual Behavior:

The following error is shown:

running make template works fine.

System information:

Operating System: Arch Linux
PROS Version: 2.6.1

Can you post the content of the project.pros inside your PROS project?

[sealj553]

It's the default from pros

{
    "py/object": "pros.conductor.project.Project",
    "py/state": {
        "project_name": "hello",
        "target": "cortex",
        "templates": { },
        "upload_options": {}
    }
}

It looks like this project was created with PROS 3 and you're working with it in PROS 2. Is that correct?

[sealj553]

I'm not sure which version the project was created with, but it's the 'template' project from the pros master branch along with pros-cli (2).
I can compile as is with just make template, but would you recommend using pros cli-3-support branch along with pros-cli3?

[edjubuh]

PROS CLI 2.x.x doesn't currently have forward compatibility with projects created with PROS CLI 3.x.x. That's not something we're currently interested in implementing, but would be open to a pull request which supports this.

[sealj553]

It appears that this error is caused by a python syntax error, not anything directly relating to project files. I figured it should be a simple fix on line 25 of prosconfig/__init__.py but I don't have much experience with python.
