Lesson 4: Import Error with solcx

[HoneyMustardRanchBBQ]

Hello! I'm having some issues when trying to run "python deploy.py" at exactly the 3:44:49 mark in the course! Here is a copy of my code in VScode:

`from solcx import compile_standard, install_solc

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",
)`

---

When I type "python deploy.py" into the terminal of VScode, I get this response in the terminal window:

"Traceback (most recent call last):
File "deploy.py", line 1, in
import solcx
ImportError: No module named solcx"

---

I have installed solcx already, as well. When I try the pip install py-solc-x command in terminal I get this response in the terminal window:

"Requirement already satisfied: py-solc-x in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (1.1.0)

Just trying to figure out how to proceed from here!
Thanks for taking the time to help!

i tried to change my python select interpere i also uninstalled solc and installed again. Also tried installing 1.1.1 and 1.1.0 versions but still im taking this error:

Traceback (most recent call last):
File "deploy.py", line 1, in
from solcx import compile_standard
ImportError: No module named solcx

can you please help me??
and here is my code:

from solcx import compile_standard
from solcx.install import install_solc

from solcx.install import SOLCX_BINARY_PATH_VARIABLE

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

# Compile Our Solidity
install_solc("0.6.0")

compiled_sol = compile_standard(
    {
        "language": "Solidty",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
            }
        },
    },
    solc_version="0.6.0",
)

import solcx

solcx.install_solc("0.8.7")

print(compiled_sol)

what solved the issue for me was using pip3 install py-solc-x instead of pip install py-solc-x

[semsion]

I'm running Ubuntu 20.04, and as Python 2 is installed, running 'python' in the terminal starts the Python 2 interpreter, which doesn't locate the installed solcx package.

If you have a similar configuration you can resolve this by using 'python3' instead, or setting python 3 as default.

[cromewar]

I highly recommend to use python 3 instead.

[slime956]

pip install py-solc

python3 -m venv env
source env/bin/activate
pip3 install py-solc-x

this work for me

[abmi108]

I uninstalled and re-installed python. This did the trick for me.

[slime956]

did you uninstall all the packages as well, honestly i gave up around the 4 hour mark, but i remember having surpassed this part, i remember having solved the error message that "solcx could not be resolved/imported" , and i dont remember how i surpassed it. i uninstalled it and ima try from scratch, hopefully it works.
