类型错误:无法使用 ReactJs 在 webpack-cli 中读取未定义的属性“presetToOptions" [英] TypeError: Cannot read property 'presetToOptions' of undefined in webpack-cli with ReactJs

问题描述

我正在开发 ReactJS 应用程序并配置了 "webpack": "^2.7.0","webpack-cli": "^2.0.9" 但是在从 cmd 运行 webpack 时出现以下错误.

I am working on ReactJS application and configured "webpack": "^2.7.0", "webpack-cli": "^2.0.9" but while running the webpack from cmd it has the following error.

const statsPresetToOptions = require("webpack").Stats.presetToOptions;
                                                                             ^

TypeError: Cannot read property 'presetToOptions' of undefined
    at processOptions (F:\reactJs_weather\React-Weather-App\node_modules\webpack-cli\bin\webpack.js:284:57)

你有什么想法吗?

推荐答案

webpack-cli 需要 至少 webpack version 4 运行.

如果您使用的是旧版本，如 webpack 2 或 3，则无需单独添加 webpack-cli 包.它已经内置于旧版本的 webpack 本身.

If you're using older version like webpack 2 or 3, you don't need to add webpack-cli package seperately. It comes already built in with older versions of webpack itself.

从第 4 版开始，整个 CLI 已被移植到一个单独的包 webpack-cli 中.

From version 4, the entire CLI has been ported inside a separate package webpack-cli.

修复应该是删除 webpack-cli 包或使用最新版本的 webpack>=4.

The fix should be to remove webpack-cli package or use latest version of webpack>=4.

有一个 正在进行的 PR 关于将 webpack 4 添加为对等依赖项，很快会弹出一个大致相同的警告.

There's an ongoing PR about adding webpack 4 as peer dependency, so soon there would a warning popping up about the same.

相关讨论:webpack 没有被列为 peer、添加 webpack 4 作为对等依赖
