运行业力时为什么"[web-server]：404: /absoluteC“

Question

我发现了几个类似的问题，但没有一个建议解决了我的问题。基本上，他们建议添加一些依赖项(我只使用本地webcomponents，所以它不适用于我的情况)或检查路径。我仔细检查了一下，路径是100%正确的。我发现一个有点奇怪的警告信息显示绝对在真正的路径之前。顺便说一句，这条路真的很酷。

Karma.conf.js

module.exports = function(config) {
    config.set({
        frameworks: ["jasmine"],
        files: [
            "../node_modules/@webcomponents/webcomponentsjs/webcomponents-bundle.js",
            { pattern: "../test/*-test.js", type: "module", included: true }
        ],
        exclude: [],
        preprocessors: {},
        reporters: ["spec"],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: true,
        browsers: ["Chrome"],
        singleRun: true,
        concurrency: Infinity
    });
};

因为在默认情况下，Karma运行在端口9876上，所以它没有能力对您的项目看得太深。相反，它劫持您的组件，并假设从该端口(它不是)可以访问所有东西。

你可以使用本指南将Karma重定向到“真实端口”。
