I have been running my code which involves deployment of smart contract to Ethereum Ropsten network. I ran this successfully for some time but last week did installed another software after which started getting these errors:

command: solc --combined-json abi,asm,ast,bin,bin-runtime,clone-bin,devdoc,interface,opcodes,userdoc
return code: 1
Invalid option to --combined-json: clone-bin

EDIT I'm running this on Jupyter notebook where environmental variable for python3.6 is set up. I have no clue why I'm getting them. Anyone can help?

  • This is compiler error - please see my complete answer here

Latest version of solc has removed few options.

The --clone-bin and --combined-json clone-bin command line options were removed.


You can downgrade the version if this functionality is required.

  • Thanks for your reply. its actually Jupyter notebook output
