Solgraph throws `TypeError: _commander.default.version is not a function`

[lmanini]

Running node v16.20.2, just installed solgraph and am facing an error with following trace:

var program = _commander["default"].version(_package["default"].version).arguments('<file>').usage(extendedHelp).parse(process.argv);
                                    ^

Sorry, this library is no longer maintained. You could try running on an older version of node.

Same issue. I modified the commander module in bin.js to support newer node versions. Replace <path/to/node_version>/solgraph/dist/bin.js with:

"use strict";

var { Command } = require("commander");
var _package = _interopRequireDefault(require("../package.json"));
var _index = _interopRequireDefault(require("./index.js"));
var _fs = require("fs");

function _interopRequireDefault(e) {
  return e && e.__esModule ? e : { default: e };
}

var extendedHelp = `
${_package["default"].description}

Example:
$ cat MyContract.sol | solgraph > MyContract.dot
$ solgraph MyContract.sol > MyContract.dot
`;

//new instance of Command API
var program = new Command();
program
  .version(_package["default"].version)
  .arguments("[file]")
  .usage(extendedHelp)
  .parse(process.argv);

var inputPromise;

if (program.args[0]) {
  inputPromise = new Promise(function (resolve, reject) {
    (0, _fs.readFile)(program.args[0], "utf-8", function (err, data) {
      if (err) {
        return reject(err);
      }
      resolve(data);
    });
  });
} else {
  inputPromise = new Promise((resolve, reject) => {
    const stdin = process.stdin;
    let data = "";

    stdin.setEncoding("utf-8");

    stdin.on("data", (chunk) => {
      data += chunk;
    });

    stdin.on("end", () => {
      if (data.trim() === "") {
        return reject(new Error("No input provided via stdin or file."));
      }
      resolve(data);
    });

    stdin.on("error", (err) => {
      reject(err);
    });
  });
}

inputPromise
  .then(function (source) {
    console.log((0, _index["default"])(source));
  })
  .catch(function (err) {
    console.error(err.message);
    process.exit(1);
  });
