Solution

  • This is a known issue for chatterbot; here are the workarounds:

    This error message indicates that there is a dependency conflict while trying to build or install a package.

    Updating Dependency Versions: Try upgrading the installed "wheel" package to make its version range compatible with the requirements of the "preshed" package. You can use either of the following commands to attempt an update:

    pip install --upgrade wheel

    or

    pip install wheel>=0.32.0,<0.33.0

    Lowering Version Requirements: If the requirements of the "preshed" package are strict, you might consider looking for a "preshed" version that is compatible with the existing "wheel" version. You can try to install a specific version of the package using the following command:

    pip install preshed==2.0.1

    Check Other Dependencies: Sometimes, the dependencies of one package can conflict with dependencies of other packages. Try checking the dependencies of other relevant packages and ensure they align with the requirements of both the "preshed" and "wheel" packages.

    Create a Virtual Environment: If you're using multiple packages in a project and their dependencies clash, consider creating a virtual environment. Virtual environments isolate dependencies for different projects, helping to avoid conflicts.
