Lesson 4 : solcx.exceptions.ContractsNotFound: Input JSON does not contain any sources

[0x3N3jVhPUV]

Here is my code:

from solcx import compile_standard, install_solc

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

# Compile our solidity
install_solc("0.6.0")

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

print(compiled_sol)

Here is my output:

Traceback (most recent call last):
  File "deploy.py", line 9, in <module>
    compiled_sol = compile_standard(
  File "/home/andyafene/.local/lib/python3.8/site-packages/solcx/main.py", line 362, in compile_standard
    raise ContractsNotFound(
solcx.exceptions.ContractsNotFound: Input JSON does not contain any sources

> stdout:

Can you help me? please

are you sure to have ./SimpleStorage.sol in the folder where you have this code?
Also, you can use 3 back-tic to add code highlighting:

```python
from X import Y
```

Thank you for the tips @AlbertoSinigaglia !
Yes, I have SimpleStorage.sol in the same folder.
To make sure it was the case, I printed, Simple_Storage_file, and it displayed the content of SimpleStorage.sol.

Here is my code:

from solcx import compile_standard, install_solc

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

# Compile our solidity
install_solc("0.6.0")

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

print(compiled_sol)

Here is the output:

Traceback (most recent call last):
  File "deploy.py", line 9, in <module>
    compiled_sol = compile_standard(
  File "/home/andyafene/.local/lib/python3.8/site-packages/solcx/main.py", line 362, in compile_standard
    raise ContractsNotFound(

please post the contract source

[0x3N3jVhPUV]

Here is the contract

// SPDX-License-Identifier: MIT

pragma solidity ^0.6.0;

contract SimpleStorage {
    uint256 favoriteNumber;

    // This is a comment!
    struct People {
        uint256 favoriteNumber;
        string name;
    }

    People[] public people;
    mapping(string => uint256) public nameToFavoriteNumber;

    function store(uint256 _favoriteNumber) public {
        favoriteNumber = _favoriteNumber;
    }

    function retrieve() public view returns (uint256) {
        return favoriteNumber;
    }

    function addPerson(string memory _name, uint256 _favoriteNumber) public {
        people.push(People(_favoriteNumber, _name));
        nameToFavoriteNumber[_name] = _favoriteNumber;
    }
}

Here is my code:

from solcx import compile_standard, install_solc

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

install_solc("0.6.0")

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

print(compiled_sol)

Here is the output:

@AlbertoSinigaglia I figured out what was the issue.

I wrote :

"source": {"SimpleStorage.sol": {"content": Simple_Storage_file}},

Instead of :

"sources": {"SimpleStorage.sol": {"content": Simple_Storage_file}},

Shame on me...
