Given this code: from solcx import compile_standard, install_solc
import json
install_solc('0.6.0')
with open('./SimpleStorage.sol', 'r') as f:
simple_storage_file = f.read()
compiled_sol = compile_standard(
{
'language': 'Solidity',
'sources': {'SimpleStorage.sol': {'content': simple_storage_file}},
'settings': {
'outputSelection': {
'*': {'*': ['abi', 'metadata', 'evm.sourceMap']}
}
}
},
solc_version = '0.6.0',
)
with open('compiled_code.json', 'w') as file:
json.dump(compiled_sol, file)
bytecode = compiled_sol['contracts']['SimpleStorage.sol']['SimpleStorage']['evm']['bytecode']['object']
print(f'bytecode: {bytecode}')I get this output: Here is my compiled_code.json: {

Hello @spencergoff the reason is you are missing the following: "outputSelection": {
"*": {
"*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]
}
}"evm.bytecode", give it a try. |

Thanks @cromewar! That worked. |

Hey @spencergoff how did you copy and paste your code into the question like that? |

thanks! For me, I realized I used "emv" instead of "evm" and it would have taken me longer to see that if I hadn't seen your response |

I have the exact same issue, BUT in my case I didn't miss the "evm.bytecode" in my code, and I still get the same error. I cannot find a solution anywhere on the whole internet. What should I do? Here's the codeÚ from solcx import compile_standard, install_solc
import json
install_solc("0.6.0")
with open("./SimpleStorage.sol", "r") as file:
simple_storage_file = file.read()
# compile our solidity
install_solc("0.6.0")
compiled_sol = compile_standard(
{
"language": "Solidity",
"sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
"settings": { "outputSelection": {
"*": {
"*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]}
}
},
},
)
with open("compiled_code.json", "w") as file:
json.dump(compiled_sol, file)
# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["evm"]["bytecode"]["object"]
# get abi
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]
print(abi)` |

Jum is is weird as it seems is not taking the compiled sol, could you please copy and paste this on your code? (just replace it) compiled_sol = compile_standard(
{
"language": "Solidity",
"sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
"settings": {
"outputSelection": {
"*": {
"*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]
}
}
},
},
solc_version="0.6.0",
)
with open("compiled_code.json", "w") as file:
json.dump(compiled_sol, file)
# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"][
"bytecode"
]["object"] |

Hey! So I have searched the whole Internet for KeyError: 'evm' too and replaced with the code you have given but it did not work. Please is there any solutions cause I stuck here and can not progress. |
