谷歌闭包编译器构建给出错误未处理标志: outputManifest‘

Question

尝试在现有的angularjs项目中实现google closure编译器。当我构建应用程序时，我得到了错误标志:未处理的标志: outputManifest。

下面是package.json：

"devDependencies": {
    "angular-mocks": "^1.7.8",
    "expect.js": "^0.3.1",
    "google-closure-compiler": "^20190909.0.0",
    "google-closure-deps": "^20190909.0.0",
    "google-closure-library": "^20190909.0.0",
    "karma": "^4.3.0",
    "karma-mocha": "1.3.0",
    "karma-phantomjs-launcher": "1.0.4",
    "less": "^3.10.3",
    "mocha": "^6.2.1",
    "ng-annotate": "1.2.2",
    "sinon": "^7.5.0"
  },
  "dependencies": {
    "angular": "^1.7.8",
    "angular-animate": "^1.7.8",
    "angular-translate": "^2.18.1",
    "bootstrap": "^3.4.1",
    "cesium": "^1.62.0",
    "jquery": "^3.4.1",
    "ol": "^6.0.1",
    "olcs": "^2.9.0",
    "proj4": "^2.5.0",
    "url-polyfill": "^1.1.7"
  }

下面是错误：

根据Closure编译器的Flags and Option文档：

--output_manifest VAL [is] Not supported by the JavaScript version

虽然我没有在您的package.json中看到closure-compiler-js，但我确实在您的错误报告中看到您正在使用它进行编译。

at mQ.TN [as Fg] (/vagrant/source/node_modules/google-closure-compiler-js/jscomp.js:8941:25657)
                                               ^^^^^^^^^^^^^^^^^^^^^^^^^^

因此，这个问题的解决方案要么停止使用JS版本，要么开始使用它支持的标志。
