3:44:45 Errors not Massive Object

[Dcamy]

Hi Patric, awesome course! Thank you so much for putting this out there!

I am stuck at 3:44:45 in the video, instead of getting the massive object I am getting a couple errors. Before I was getting a lot more errors along the way and have slowly whittled them down but this one has stopped me cold.

If anyone has any suggestions please let me know :)

This is the second time we run $ python deploy.py

Here is my error

$ python deploy.py INFO: Could not find files for the given pattern(s).

"""
    Compile Solidity contracts using the JSON-input-output interface.

    See the Solidity documentation for details on the expected JSON input and output
    formats.

    Arguments
    ---------
    input_data : Dict
        Compiler JSON input.
    base_path : Path | str, optional
        Use the given path as the root of the source tree instead of the root
        of the filesystem.
    allow_paths : List | Path | str, optional
        A path, or list of paths, to allow for imports.
    output_dir : str, optional
        Creates one file per component and contract/file at the specified directory.
    overwrite : bool, optional
        Overwrite existing files (used in combination with `output_dir`)
    solc_binary : str | Path, optional
        Path of the `solc` binary to use. If not given, the currently active
        version is used (as set by `solcx.set_solc_version`)
    solc_version: Version, optional
        `solc` version to use. If not given, the currently active version is used.
        Ignored if `solc_binary` is also given.
    allow_empty : bool, optional
        If `True`, do not raise when no compiled contracts are returned.

    Returns
    -------
    Dict
        Compiler JSON output.

Update: Found https://ethereum.stackexchange.com/questions/110405/having-a-problem-with-solc-x-version-solc-0-6-0-has-not-been-installed and made the changes updating 2 lines of code and ran npm install -g solc

New code

from solcx import compile_standard, install_solc

I stared at this code for 2 days making no progress... and the I noticed "source" should be "sources" WITH A SECOND "s" at the end... fml... new issue... "solidity" should be "Solidity" with a capital "S"

New code works perfectly! Finally moving on! :)

from solcx import compile_standard, install_solc

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

# Compile our Solidity

install_solc("v0.6.0")
compile_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
            }
