node.js - 开始使用 webpack 4 的问题

Question

我完全按照给定的教程进行操作 here .但令我惊讶的是，这些文档似乎已经过时了。例如

npx webpack src/index.js dist/bundle.js 失败:

The CLI moved into a separate package: webpack-cli. Please install 'webpack-cli' in addition to webpack itself to use the CLI. -> When using npm: npm install webpack-cli -D -> When using yarn: yarn add webpack-cli -D

如果我安装 webpack-cli 并重试，我会看到此错误:

Hash: af9bc06fd641eb0ffd1e Version: webpack 4.0.0 Time: 3865ms Built at: 2018-2-26 05:10:45 1 asset Entrypoint main = main.js 1 (webpack)/buildin/module.js 519 bytes {0} [built] 2 (webpack)/buildin/global.js 509 bytes {0} [built] [3] ./src/index.js 212 bytes {0} [built] [4] multi ./src/index.js dist/bundle.js 40 bytes {0} [built] + 1 hidden module

WARNING in configuration The 'mode' option has not been set. Set 'mode' option to 'development' or 'production' to enable defaults for this environment.

ERROR in multi ./src/index.js dist/bundle.js Module not found: Error: Can't resolve 'dist/bundle.js' in '/var/app/webpack_demo' @ multi ./src/index.js dist/bundle.js

我希望我没有做一些疯狂的事情，鉴于 webpack 的流行，文档应该反射(reflect)实际行为。让我知道我是否做错事了。

编辑

升级到 webpack 4 的详细说明，这可能会有所帮助

您可以在 webpack config 或 cli 命令中传递 mode 参数。

配置:mode: 'development' 或 mode: 'production'

CLI:webpack --mode development 或 webpack --mode production
