Webpack:让它忽略找不到的源文件? [英] Webpack: make it ignore source files that can't be found?

问题描述

我正在使用 snabbdom.js 和 webpack 来构建一个 JS 前端应用程序.我有一个非常简单的 snabbdom 视图和捆绑它的 webpack 配置.当我在 chrome 中加载包时，我在控制台中得到了所有这些东西:

I'm using snabbdom.js and webpack to build a JS front-end app. I have a very simple snabbdom view and webpack config that bundles it up. When I load the bundle in chrome I get all this stuff in the console:

我可以将 webpack mode 设置为 production 这确实消除了这些警告，但它也会关闭 all 源映射，所以不是很有帮助.我发现了另一个相关问题 描述如何使用插件加载它们.但是我不想为我实际上不想要的源映射配置插件而烦恼.有没有办法告诉 webpack 忽略这些?

I can set the webpack mode to production which does get rid of these warnings but it also turns off all source maps, so that's not really helpful. I found this other related question that describes how to use a plugin to load them. But I don't want to mess around with configuring a plugin for source maps I don't actually want. Is there a way to tell webpack to just ignore these?

推荐答案

我在 webpack devtools 选项 并发现添加devtool: 'eval-cheap-source-map', 到我的 webpack 配置就可以了.

I read up a bit more on the details of each option in the webpack devtools options and found that adding devtool: 'eval-cheap-source-map', to my webpack config did the trick.

来自文档:

它没有列映射，它只映射行号.它忽略来自加载器的 SourceMaps，只显示类似于 eval devtool 的转译代码

it doesn't have column mappings, it only maps line numbers. It ignores SourceMaps from Loaders and only display transpiled code similar to the eval devtool
