Loading "grunt-karma.js" tasks...ERROR >> SyntaxError: Unexpected identifier

Question

加载 "grunt-karma.js" 个任务时出错。所有其他任务加载正常。在更新了一些依赖项（包括 g运行t-karma 和 karma）后开始发现问题。

来自我的package.json：

"grunt-karma": "^3.0.2", "karma": "^4.2.0",

我在 Gruntfile.js 中的 Karma 配置：

/**
 * The Karma configurations.
 */
karma: {
    options: {
        configFile: '<%= build_dir %>/karma-unit.js'
    },
    unit: {
        port: 9019,
        background: true
    },
    continuous: {
        singleRun: true
    }
},

当我运行 g运行t watch --verbose --debug 这是我看到的错误：

Registering "grunt-karma" local Npm module tasks.

我将我的 karma 版本恢复到 3.1.4 并且不再看到问题：

"karma": "^3.1.4",

也尝试了 Karma 4.0.0 版，但错误仍然存在。
