ethereum remix 中的简单智能合约 - ParserError: Expected ';'

Question

我尝试测试一些简单的智能合约，但不知道我有错误有人能告诉我哪里有错误吗？

我想测试这段代码，但这个错误阻止了我。

interface IERC20Token {
    function balanceOf(address owner) public returns (uint256);
    function transfer(address to, uint256 amount) public returns (bool);
    function decimals() public returns (uint256);
}

contract TokenSale {
    IERC20Token public tokenContract = '0x12740510086c7062d5131BFe7C680c8b5D728c7f' // the token being sold
    uint256 public price = 1000000000000000;              // the price, in wei, per token
    address owner;

    uint256 public tokensSold;

    event Sold(address buyer, uint256 amount);

    function TokenSale(IERC20Token _tokenContract, uint256 _price) public {
        owner = msg.sender;
        tokenContract = _tokenContract;
        price = _price;
    }
