我有一个app的结构(node_modulesdir从这个列表中排除):
??? actions.js
??? bundle.js
??? components
? ??? App.js
? ??? Footer.js
? ??? Link.js
? ??? Todo.js
? ??? TodoList.js
??? Containers
? ??? AddTodo.js
? ??? FilterLink.js
? ??? VisibleTodoList.js
??? index.html
??? index.js
??? main.js
??? package.json
??? package-lock.json
??? reducers.js
??? webpack.config.js
我的webpack配置如下所示:
module.exports = {
entry: "./main.js",
output: {
path: __dirname,
filename: "bundle.js"
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel-loader',
query: {
presets: ['es2015', 'react']
}
}
]
} …截至昨天下午，我们的 Javascript 单元测试套件开始失败。在出现一串 Module not found 错误后，没有任何测试运行并且 webpack 报告构建失败。这是我们的构建堆栈：
Node 6.11.5（是的，我知道，很旧） Karma 1.7.1 Webpack 2.2.1 React 15.6.2
我们使用 Karma 运行我们的单元测试。大部分测试套件都涉及 React，所以我们使用 Webpack 来构建一切。为此，我们导入我们的 webpack 配置，然后将各种值插入 Karma webpack 配置。
直接使用 Webpack 构建脚本工作正常，但是当我们尝试运行时，karma start我们会遇到很多这样的错误：

module.exports = {
chainWebpack: config => {}
}
编译时我收到以下错误：
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'
- install 'path-browserify'
If you don't want to include a polyfill, you can …我在运行时收到以下错误列表ng serve。
