Check Dependencies and Version Compatibility Ensure that all used libraries (such as  pyscrum  and  solders ) are correctly installed and that their versions are compatible with each other. Sometimes, version mismatches can lead to import errors. You can try to update these libraries to the latest versions to see if the problem can be solved:

bash

pip install --upgrade pyscrum pip install --upgrade solders Check PublicKey Import Errors Carefully check the import path and usage of  PublicKey . There may be path errors or import problems due to changes in the library structure. If  PublicKey  is in the  solders  library, ensure that the  solders  library is correctly installed and imported. You can try to reinstall the  solders  library:

bash

pip uninstall solders pip install solders Debugging and Error Handling Add detailed error - handling and debugging statements to the code to get more information about the import error. For example:

python

try: from solders.pubkey import Pubkey except ImportError as e: print(f"ImportError: {e}")

This can help determine the specific cause of the error, such as missing dependencies or naming conflicts.
