Python error when trying to create genesis block

Hey, I'm getting apython error when I'm trying to generate the genesis block:

python ./mk_genesis_block.py --extradata 0x11bbe8db4e347b4e8c937c1c8370e4b5ed33adb3db69cbdb7a38e1e50b1b82fa

Have you tried upgrading bitcoin pip lib:
(sudo) pip install --upgrade bitcoin

Yeah. that didn't help, however adding --insight worked. Thanks!

im getting exactly the same error but --insight isnt working for me... anybody an idea?


python mk_genesis_block.py --extradata --insight 0x11bbe8db4e347b4e8c937c1c8370e4b5ed33adb3db69cbdb7a38e1e50b1b82fa > genesis_block.json
Traceback (most recent call last):

The hash is an argument for extradata, should be appended after it, like that:

python mk_genesis_block.py --extradata 0x11bbe8db4e347b4e8c937c1c8370e4b5ed33adb3db69cbdb7a38e1e50b1b82fa --insight > genesis_block.json

I am at only block 288

@fynn thanks for that

Is anyone else having a syntax error with the script? I keep getting the following response:
File "mk_genesis_block.py", line 293
print json.dumps(evaluate(), indent=4)
^
SyntaxError: invalid syntax

J_Grahn

@HCubed I think you're using Python 3. print is a function: print(json.dumps(evaluate(), indent=4) There will be other changes needed as well. Install Python 2 and solve all of your problems at once.

HCubed

Thanks J_G... did that after checking a few other threads, and it worked. Forgot to update here...

i do have this problem, even with insight

sclopit

after having updated the python bitcoin module

sudo pip install --upgrade bitcoin

I launch

mk_genesis_block.py --extradata 0x11bbe8db4e347b4e8c937c1c8370e4b5ed33adb3db69cbdb7a38e1e50b1b82fa --insight > genesis_block.json

and receive the error message

please advise

thanks in advance

ok, I managed to generate

genesis_block.son

by *omitting* the --insight flag.

maybe the meaning of that flag (what it does, when it should/should not be used) is super-obvious to the inner circle of Ethereum developers.

but you have no idea how confusing/frustrating this all is from someone on the outside.

@sclopit "By default, the script uses Blockr and Blockchain.info to fetch the Genesis pre-sale results. You can also add the --insight switch if you’d instead prefer to use the private Ethereum server to obtain this information. If you are facing issues with the script, please raise an issue on its github."
