@ozeron https://github.com/ai-christianson/RA.Aid this is the actual devs repo and he fixed this issue already

[natea]

@sosacrazy126 can you link to the bug/issue or git commit in his repo that fixes this bug?

I tried pip installing the latest code directly from git, and for some reason it downgraded my version of ra.aid to 0.11. How is it possible that the package on pypi is a newer version than the code in github?

I'm still getting the error Error running interactive capture even after installing the latest code.

@ozeron were you able to resolve this issue?

[vivmagarwal]

Hi @ruvnet, thanks for all of your awesome work!

I am stuck and not able to try SPRAC due to this error! Can you kindly help.

[crscheid]

Are you on a Mac by chance? I am and I had the same error.

Based on my research, it appears that this is because the default BSD-based script command on a Mac does not take the argument -c. See here for where that command appears to be used. One would need to ensure that this function can detect BSD and non-BSD based systems and provide a method to run it when its on a Mac.

Since I'm just testing and tinkering at this stage, as a workaround, I downloaded Sparc directly and installed via pip install -e .. Then I went into the code here and changed it around so that it would work on my system. But it probably should be fixed if its to work more generally.

[natea]

@crscheid what specific change did you make in order to get it to work on your Mac?

I agree with you that it should be fixed to work more generally (on BSD and non-BSD), but in order to run it on my own machine, it would be great to know how you got it working!

I asked Cursor what it suggested, and here is the suggested code to make it work both on Mac and Linux:

        if os.uname().sysname == 'Darwin':  # macOS
            os.system(f"script -F {shlex.quote(output_path)} {shlex.quote(shell_cmd)}")
        else:  # Linux
            os.system(f"script -q -c {shlex.quote(shell_cmd)} {shlex.quote(output_path)}")

[crscheid]

Very quick hack. Doesn't even check what system is running. I just needed to do some testing. But here is my code:

sparc_cli/proc/interactive.py

How are you installing the sparc command line tool to make sure it's using the one you modified and not the wheel downloaded from pypi?

Also, it's complaining about a legacy version of sparc_cli:

Installing collected packages: sparc
  DEPRECATION: Legacy editable install of sparc==0.87.6 from file:///Users/nateaune/Desktop/everydai/sparc/sparc_cli (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at https://github.com/pypa/pip/issues/11457
