ERROR: Cannot install aider-chat==0.5.0, aider-chat==0.5.1, aider-chat==0.5.2 and aider-chat==0.5.3 because these package versions have conflicting dependencies.
The conflict is caused by:
aider-chat 0.5.3 depends on aiohttp==3.8.4
aider-chat 0.5.2 depends on aiohttp==3.8.4
aider-chat 0.5.1 depends on aiohttp==3.8.4
aider-chat 0.5.0 depends on aiohttp==3.8.4
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ASSISTANT: It seems there is a dependency conflict when trying to install `aider-chat` from TestPyPI. The conflict is caused by the `aiohttp` package version. To resolve this issue, you can try the following steps:
1. Update the `requirements.txt` file to loosen the version constraint for `aiohttp`. For example, you can change it to `aiohttp>=3.8.4` to allow any version greater than or equal to 3.8.4.
2. Update the `setup.py` file to read the updated `requirements.txt` file.
3. Re-upload the package to TestPyPI with the updated dependencies.
Here's the change you need to make in the `requirements.txt` file:

USER: why is it trying to install multiple versions of aider-chat?
ASSISTANT: The reason pip is looking at multiple versions of `aider-chat` is that it's trying to find a version that is compatible with the other packages and their dependencies in your environment. This process is part of pip's dependency resolution mechanism.
In this case, it seems that all the versions of `aider-chat` have a conflicting dependency on `aiohttp==3.8.4`. To resolve this issue, you can try loosening the version constraint for `aiohttp` in the `requirements.txt` file, as I mentioned in my previous response. This should help pip find a compatible version of `aider-chat` that works with the other packages in your environment.
USER: I added these *read-write* files: requirements.txt
ASSISTANT: Great! Now, let's update the `requirements.txt` file to loosen the version constraint for `aiohttp`. Change the line with `aiohttp==3.8.4` to `aiohttp>=3.8.4`. Here's the change you need to make:
```plaintext
requirements.txt
<<<<<<< ORIGINAL
aiohttp==3.8.4
=======
aiohttp>=3.8.4
>>>>>>> UPDATED
```
After making this change, you can re-upload the package to TestPyPI with the updated dependencies and try installing it again.
