Deploying Balancer Contracts -> ParserError: Expected pragma on @balancer-labs/v2-interfaces && @balancer-labs/v2-solidity-utils

[0xEmilio]

I created a new hardhat project and moved the contracts for weighted pools in.

When I call npx compile, I am met with:

PS C:\Users\---\Documents\programming\---\hardhat> npx hardhat compile
@balancer-labs/v2-interfaces/contracts/solidity-utils/helpers/BalancerErrors.sol:24:1: ParserError: Expected pragma, import directive or contract/interface/library/struct/enum definition.
function _require(bool condition, uint256 errorCode) pure {
^------^

@balancer-labs/v2-solidity-utils/contracts/helpers/ScalingHelpers.sol:35:1: ParserError: Expected pragma, import directive or contract/interface/library/struct/enum definition.
function _upscale(uint256 amount, uint256 scalingFactor) pure returns (uint256) {
^------^

Error HH600: Compilation failed

my hardhat config:

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: {
    version: "0.7.0",
    settings: {
      optimizer: {
        enabled: true,
        runs: 200,
      },
    },
  },
};

and deps

        "@balancer-labs/v2-interfaces": "^0.4.0",
        "@balancer-labs/v2-pool-utils": "^4.1.1",
        "@balancer-labs/v2-solidity-utils": "^4.0.0"
      },```

Curious if this is me doing something dumb or if compilation fails due to an actual issue. Thanks.

Seems like the code is not encapsulated, doing do requires refactoring so much.
