Import "solcx" could not be resolved

[yarg119]

I keep getting this error. anyone know what I can do about this. I just got to the point where I am using Visual Studio Code, and this error seems to one that can jack up an entire contract. I downloaded all of the dependencies and troubleshooting to get rid of all of the errors that were coming up during installation. I've been working on this for about two hours now, and I need some help.

solcx.install_solc: The term 'solcx.install_solc' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Update when I try to deploy

[yarg119]

I did not fix this issue, however, I was able to run deploy.py

Hello @yarg-eth did you change the python interpreter on vscode (bottom left corner) and choose the one you have solc-x installed on?

[yarg119]

No, I had not. This fixed the error message. Thank you so much.

[yarg119]

To clarify, if you have some extra extensions installed. It is the curly brackets on the bottom bar of your vscode that allows one to change their python interpreter.

I have a similar problem, @cromewar , i installed solcx, however it keeps giving me this error, i tried changing the interpreter but it doesn't work!
solcx.exceptions.SolcNotInstalled: solc 0.6.0 has not been installed. Use solcx.install_solc('0.6.0') to install.

Hello @nixon-crypto please refer to chronological-issues-from-video.md there you will have more info about some lines you must add to that lesson in order to work.

[marescialloNino]

thank you @cromewar

As far as I can tell the plug in is 'broken' with higher versions of Python. If I can figure out a virtual environment with an earlier version (3.8 maybe) it might work. There's no indication that anyone is working on a fix for this so a note should be added to the video regarding what version of Pythons it works with

Can anyone assist? I keep getting the following error:

\demos\web3_py_simplestorage\deploy.py", line 1, in
from solcx import compile_standard, install_solc
ModuleNotFoundError: No module named 'solcx'

Had this resolved and then it came back, cant continue the course for the time being.
Here is my code:

from solcx import compile_standard, install_solc
import json

from web3 import Web3

install_solc("0.6.0")

with open("./SimpleStorage.sol", "r") as file:
simple_storage_file = file.read()

compiled_sol = compile_standard(
{
"language": "Solidity",
"sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
"settings": {
"outputSelection": {
"": {"": ["abi", "metadata", "evm.bytecode", "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"]

abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]

w3 = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545"))
chain_id = 5777
my_address = "0x3748F7ACa1d2cadeb0b52F6E72CEA058E1760526"
private_key = "0x73dc41d1cd1bcb782bd9300d3eae36d1c475c59a9ee463c77012ac11039ef903"

SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
print(SimpleStorage)

@JohnEMagee there is actually a difference between python and python3 on mac (as python uses python 2.7) are you using a m1 chip mac?

[JohnEMagee]

I am yes - in the thread I started myself regarding this issue I spelled it out, I'm using an m1 mac mini - i know it has issues with certain things but I usually find work arounds, didn't find one for this yet...

[solanamagic]

I will give it another try today but if the plug-in is broken does that mean that I will struggle to continue with the course?

[JohnEMagee]

Maybe? I've made it through to 6 just by switching to solana 0.8.12 - you have to do some tweaking along the way but it's not huge. I'm waiting on an answer about the chainlink plug ins because that causes an issue too since you can't use solidity 0.6.0 to compile those either

[yarg119]

@solanamagic you might have to reinstall everything. Once I got to the part with brownie, I had to uninstall python and everything with that. What I would do is start fresh, uninstall everything that you can and reinstall it but make sure to delete the leftover directories after uninstallation. Some of this is probably completely unrelated with your problem now, but it will save you a lot of time and similar problems later in the course.
