solc.compile_source() Failed

• py-solc Version: 2.1.0
• solc Version: 0.4.21 (here is solcjs)
• Python Version: 3.5.4
• OS: linux(ubuntu)

What was wrong?

Use compile_source(source) fail !!

My commands:

Install solc: npm install -g solc Install py-solc: pip3 install py-solc Use solc in python3: from solc import compile_source compile_source(‘pragma solidity ^0.4.0; contract A{ funcion A() public{}}’)

Details:

Traceback (most recent call last): File “<stdin>”, line 1, in <module> File “/usr/local/lib/python3.5/dist-packages/solc/main.py”, line 106, in compile_source stdoutdata, stderrdata, command, proc = solc_wrapper(**compiler_kwargs) File “/usr/local/lib/python3.5/dist-packages/solc/utils/string.py”, line 85, in inner return force_obj_to_text(fn(*args, **kwargs)) File “/usr/local/lib/python3.5/dist-packages/solc/wrapper.py”, line 165, in solc_wrapper stderr_data=stderrdata, solc.exceptions.SolcError: An error occurred during execution command: solc --combined-json abi,asm,ast,bin,bin-runtime,clone-bin,devdoc,interface,opcodes,userdoc return code: 1 stderr:

Its possible that @ajax-2 hit another issue before hitting the syntax error. When I ran the example snippet I got:

        <stdin>:1:46: Error: Expected token Semicolon got 'LParen'
pragma solidity ^0.4.0; contract A{ funcion A() public{}}

I am using the apt packaged solc. Im wondering if the version of solc installed by the npm package is different than the regular solc binary. I also thought that the npm solc command was “solcjs”, which definitely does behave differently.

EDIT: @ajax-2 It does appear you are using solcjs instead of the solc binary. Did you link the solcjs executable to solc? I would remove that link and install the solc binary via apt:

sudo apt-get install solc

Example showing solcjs error output when piping the source:

$ echo 'pragma solidity ^0.4.0; contract A{ function A() public{}}'|solcjs --combined-json abi,asm,ast,bin,bin-runtime,clone-bin,devdoc,interface,opcodes,userdoc

There is a typo in your solidity snippet. Missing the T in function. Should be:

compile_source('pragma solidity ^0.4.0; contract A{ function A() public{}}')
