getting invalid syntax at offset 275

Issue

Hi there, I just installed aider (in a virtual environment) version v0.43 (also tried with v0.43.1-dev) and am trying to run it. Whenever I do, the prompt loads correctly, but if I tell it to do something it throws this error:

Version and model info

No response

[nathanbraun]

Update: I got it working on the repo I was using with the --no-git option. I'm really not sure what the deal is. I do have sub modules in this repo, but I tried installing this same submodule in a different test repository and it worked fine. I guess I'll use it with the --no-git option for now. Let me know if you want any more info to debug.

I did try running it on python versions 3.12, 3.11, and 3.10 and got the same behavior on all of them.

Thanks for trying aider and filing this issue.

How did you install aider? This looks like it might be a problem with your local python environment.

[nathanbraun]

I'm on a mac and made a new virtual environment for it, activated it, then ran:

$ pip install aider-chat

Then when I want to run it somewhere else, I have this environment activated, and run it in a different working directory. It works, but only with --no-git.

[paul-gauthier]

Does this happen for you with every .ts file? I am unable to reproduce this problem.

[nathanbraun]

It doesn't appear to be language specific. I just tried it same repo and it crashed with the same error when I ran:

/add package.json

[paul-gauthier]

This seems to be an issue with your local environment. Perhaps you should try uninstalling aider and re-installing it cleanly? Or try installing via pipx:

https://aider.chat/docs/install/pipx.html

I am unable to reproduce the problem. I've never received other user reports of similar issues. And nothing about this part of aider has changed for many months.

[cjoach]

Hi, I have the same problem. I installed using pip3 install --local aider-chat then pipx install aider-chat. I tried the --no-git option and it indeed works in this case.

SyntaxError: Invalid syntax at offset 275

[cjoach]

I was able to isolate my problem by creating a new repo with a single elm file then running the comment aider --show-repo-map. This seems to be related to the file tree-sitter-elm-tags.scm. I also tested the language.query(query_scm) for all scm files and the Ocaml one is the only other to fail but with the following error:

NameError: Invalid node type infix_operator

[nathanbraun]

Thanks for looking at this @cjoach -- my repo it's failing on indeed also does have Elm files in it.

[paul-gauthier]

@cjoach submitted a PR that should fix this. Thanks!

I had aider add test coverage for all supported languages as well. The tests failed on elm until the PR was merged, so this seems like it may be fixed.

The change is available in the main branch. You can get it by installing the latest version from github:

python -m pip install --upgrade git+https://github.com/paul-gauthier/aider.git

If you have a chance to try it, let me know if it works better for you.

[cbrake]

I ran into the same problem with this project:

https://github.com/simpleiot/simpleiot

And your fix works for me -- thanks!
