找不到+ Karma +茉莉+ JavaScript的源映射

Question

我正在为每个js文件接收此消息。打字稿文件工作正常。我尝试添加--source-map=false标志，但效果不佳。我的tsconfig.json文件也已经有sourceMap: false，但也许不应该影响我的问题，因为它仅影响js文件？

这是我第一次使用karma，所以我想我可能在karma.conf.js中缺少javascript文件。

karma.conf.js文件：

module.exports = function (config) {
    config.set({
        hostname: 'localhost',

        basePath: '.',

        frameworks: ['jasmine', 'karma-typescript'],

        files: [

            // [some patterns ...]

            // [some ts and js files (production code), e.g:] ...
            'src/app/spas/tds-web/**/*.ts',

            'spec/**/*.ts',
            'spec/**/*.js'
        ],


        exclude: [''],

        preprocessors: {
            'src/**/*.js': ['coverage'],
            '**/*.ts': ['karma-typescript', 'coverage'],
        },

        karmaTypescriptConfig: {
            coverageOptions: {
                exclude: [/(\-|\.)(d|spec|test)\.ts$/i]
            },
            reports: {
                'html': 'coverage',
                'lcovonly': {
                    'directory': 'coverage/typescript',
                    'subdirectory': 'lcov',
                    'filename': 'lcov.info',
                },
                'text-summary': ''
            }
        },


        reporters: ['progress', 'karma-typescript', 'coverage'],

        port: 9876,

        colors: true,


        logLevel: config.LOG_INFO,


        browsers: ['chromeWithoutSecurity'],
        browserNoActivityTimeout: 100000,

        customLaunchers: {
            phanthomjsWithoutSecurity: {
                base: 'PhantomJS',
                flags: ['--ignore-ssl-errors=true', '--web-security=false']
            },
            chromeWithoutSecurity: {
                base: 'Chrome',
                flags: ['--args', '--ignore-certificate-errors']
            }
        },


        singleRun: true,

    });
};

我在karma.conf.js的files处收到的每个js文件的完整消息：

Answer 1

您收到此错误，因为覆盖率报告找不到源地图。如果您对代码覆盖率不感兴趣，则可以通过从报告部分删除lcov和'html': 'coverage',来将其关闭。

如果覆盖率报告很重要，那么我不确定在这里建议什么。您在使用webpack吗？
