在我的 Gulp 文件中加入 2 个字符串会出现无意义的错误？

Question

在 OSX 上使用节点 16.2.0。我刚接触 Gulp。

我想更新我的 package.json 文件中的 version，如果在功能分支上，该文件将包含 Git 散列，所以我的 Gulp 中有这个文件

// 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，得到了无意义的错误

$ gulp manageVersion -f gulpfiles/version.js

        if (v1[key] !== v2[key]) {
                          ^

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

Answer 1

原来我必须 trim 来自 getHash() 函数的字符串

hash = getHash().trim();

在我的 Gulp 文件中加入 2 个字符串会出现无意义的错误？

Joining 2 strings in my Gulp file gives a non-sensical error?
