在OSX上使用节点16.2.0。我是Gulp的新手。
我想更新我的package.json文件中的version，如果在功能分支上，它将包含Git哈希，所以我在我的Gulp文件中有这个

// pkg is defined somewhere else to be my Gulp file
// I have a "semVer" key in my package.json file
const {src, dest} = require('gulp');
const semver = require('semver');
...
const semVer = semver.parse(pkg.semVer);

// Functions getBranch() and getHash() are defined somewhere else,
// and they return the Git branch and hash respectively.
function manageVersion() {
  var newVersion = semver.inc(semVer, 'patch');
  var hash = "";
  if (getBranch().includes('feature')) {
    hash = getHash().toString();
    newVersion = [newVersion, hash].join('-');
  }
  src(['../package*.json'])
    .pipe(gulp_bump({
      version: newVersion
    }))
    .pipe(dest('./'));
}
exports.manageVersion = manageVersion

然后我这样做，得到无意义的错误

$ gulp manageVersion -f gulpfiles/version.js

我已经检查了newVersion和hash的所有值，它们都是有效的字符串。我遗漏了什么？
