Angular js gulp sourcemap ngannonate 和 babel 中 JavaScript 堆内存不足

Question

我在我的 Angular JS 项目中使用 es6 语法，但在运行 gulp build 时会抛出错误，在 github 上搜索，所以有人说这是由于 gulp uglify 导致的错误，而有人说这是 babel问题和其他问题说 ng-annonate 问题。

ubuntu 14.04

节点-v:8.4.0

npm -v:5.3.0

babel --版本:6.26.0(babel-core 6.26.0)

gulp/.babelrc

{
    "presets": ["es2015"],
    "plugins": ["syntax-decorators", "ng-annotate"] // this line is added after seeking for solution
}

gulp/build.js相关代码

.pipe(jsFilter)
    .pipe($.sourcemaps.init())
    .pipe($.babel({"presets": [ ["es2015", { "modules": false} ] ], compact: false}))
    .pipe($.ngAnnotate())
    .pipe($.uglify({
      preserveComments: $.uglifySaveLicense
    })).on('error', conf.errorHandler('Uglify'))
    .pipe($.sourcemaps.write('.'))
    .pipe(jsFilter.restore)

还按照this solution尝试了.pipe(uglify({compress: {sequences: false, join_vars: false}})) 。但没有帮助

这是执行gulp build时的日志

这可能只是因为您的应用程序需要大量内存来构建； Node.js 对内存分配有 1.4Gb 的硬性限制。请参阅this question关于如何增加这个限制。如果这有帮助，请告诉我们!
