package.json片段

  • poi：9.2.4
  • 业力：^ 1.7.1
  • karma-chai：^ 0.1.0
  • karma-mocha：^ 1.3.0
  • karma-webpack：^ 2.0.6
  • 摩卡：^ 4.0.1
  • poi-preset-karma：^ 9.2.2
  • webpack：^ 3.9.1

poi.config.json 

module.exports = {
    presets: [
        require('poi-preset-karma')({
            port: '5050'
        })
    ],
    webpack(config) {
        config.devtool = 'source-map';
        config.watchOptions = {
            ignored: '/node_modules',
            poll: 1000,
        };
        config.stats = {
            depth: true,
            warnings: true,
        };
        return config;
    },
    define: {
        __VERSION__: require('./package.json').version
    },
    html: {
        title: 'Platform',
        template:'index.ejs'
    }
};

当我运行命令 poi test 时，我得到以下输出：

> Using main field in package.json as entry point

我尝试查看一些webpack代码，看看有什么遗漏，但我不确定。似乎问题是webpack期望至少定义一个模式选项，但事实并非如此。我尝试在POI的开发者网站https://poi.js.org/#/上查看示例，但找不到任何内容。

任何人都知道之前缺少什么或遇到过这个问题？

1 个答案:

答案 0 :(得分：0)

我终于能够解决问题了。想我真的没有对karma-webpack的依赖。所以我删除了它，删除了node_modules /并清除了我的本地缓存。为了安全起见，我从节点9.0.0降级到8.9.1（lts）。
