这真让我抓狂。我负责开发并需要合并分支，但正是在我的机器上，只有某些东西不起作用。

我已经多次删除node_modules并运行npm install，甚至完全克隆了 repo 并重新设置了所有内容，但我总是会遇到同样的问题。

有人将代码与 ES6 合并，所以我们需要对其进行转译，因为 minifier 插件不适用于 ES6 代码。

所以我们使用gulp-babel

var
          gulp  = require('gulp')
         //more requires
        , babel = require('gulp-babel')

var libs_js = [
   //list of javascripts
]

gulp.task('js-build', function () {
  gulp.src(libs_js)
    .pipe(sourcemaps.init())
    .pipe(ngAnnotate())
    .pipe(running_task != 'js-build' ? _bypass() : tap(function(f) { f.contents = new Buffer('document.write(\'<script src="' + f.path.replace(process.cwd(), '') 
        .replaceAll('\\','/') // fix paths for windows
      + '"><\/script>\')') })) 
    .pipe(concat(pkg.name + '.js', {newLine: '\n;'}))
    .pipe(babel({presets: ['es2015'],compact: false}))
    .pipe(running_task == 'js-build' ? _bypass() : uglify())
    .pipe(sourcemaps.write('.'))
    .pipe(gulp.dest('dist'))
    .on('end', function () {
      console.log('[' + new Date + '] js compiled')
    })  
});

//other gulp targets

gulp.task('prod', ['js-build', 'css', 'sass', 'assets', 'libs']);

running gulp prod，对每个人都有效，但对我来说，我得到：

"latest"首先，如果在我们使用的代码中，为什么要抱怨es2015. 我去另一台计算机上运行了所有东西，它工作的地方，我发现了一些令人惊讶的事情：

在我的机器上：

它们不一样！！！！ 这怎么可能？我的意思是我在两台机器上使用了完全相同的命令，对每个人都是一样的，除了andpackage.json之外没有其他命令已经运行（我什至使用 gulp from ）npm installgulp prodnode_modules/.bin/gulp

我唯一能想到的事情是： - 有一些二进制文件可能会导致问题 - 节点或 npm 版本？在此处使用节点 5.1 - 一些并发问题，因为我的 PC 使用的是 SSD 存储？

供参考，在这里package.json

将此添加到您的 package.json

“巴别塔”：{“预设”：[“es2015”]}，

或者如果你有一个现有的 .babelrc
