solidity_flattener -h crashes

[yaronvel]

I just try solidity_flattener -h and get

  File "/usr/local/bin/solidity_flattener", line 27
    print("FATAL: '{name}' was defined multiple times. Aborting.".format(name=contract_name), file=sys.stderr)

I am using ubuntu with python 3.5.

Same thing here:
File "/usr/local/bin/solidity_flattener", line 27
print("FATAL: '{name}' was defined multiple times. Aborting.".format(name=contract_name), file=sys.stderr)
^
SyntaxError: invalid syntax

Sorry, using Mac OS Sierra 10.12.6 and Python 3.6.2

This error happens if the script is executed under Python2. Will be looking into how to address this. Thanks for the report!

I think the easiest way to fix this is to change the shebang-line to, instead of pointing to the common location of /usr/bin/python, to /usr/bin/python3. Whether this is something you can do easily, or if it is something that pip usually manages for you and is hard to alter, I do not know.

At least, manually altering that line using sudo vim /usr/bin/solidity_flattener solved the problem for me, for now 🙂.

pip has been updated with the latest package. Please run pip3 install solidity-flattener --no-cache-dir -U in order to grab it, should be listed as version 0.2.0.

Thank you for the reports, everybody!
