虽然错误是指缺少脚本构建，但我已经在我的 package.json 中放置了一个构建"脚本

<代码>{"name": "es6",版本":1.0.0"，"main": "index.js",脚本":{构建":webpack"},关键字":[]，作者": ""，"许可证": "ISC",开发依赖":{"webpack": "^3.8.1"}}

这是我的 webpack.config.js 文件

module.exports = {条目:['./app/index.js']，输出: {路径:'./build',文件名:'bundle.js'}}

谁能告诉我如何修复这个错误或者它来自哪里.我是使用 node.js、webpack 和命令行的新手.提前感谢您的时间！

解决方案

  1. 尝试将 webpack.config.js 中的 output.path 设置为绝对路径

    module.exports = {条目:['./app/index.js']，输出: {路径:__dirname + '/build',文件名:'bundle.js'}}

    我没有 Windows(在 Linux 上)但使用节点 8.16.0 和 npm 6.4.1，复制您的 package.json 和 webpack.config.js，我收到以下错误:

    无效的配置对象.Webpack 已使用与 API 架构不匹配的配置对象进行初始化.- configuration.output.path:提供的值./build"不是绝对路径！->输出目录为**绝对路径**(必需).

    在

我为模仿您的设置所做的步骤:

  1. 复制你的 package.json 和 webpack.config.js
  2. 运行 npm i(或 npm install)
  3. run npm run build - 收到上面提到的无效配置错误
  4. 将 output.path 更改为与 __dirname 连接的绝对路径(不确定 Windows 是否不同...)
  5. 重新运行 npm run build 并得到:

    多个 ./app/index.js 中的错误找不到模块:错误:无法解析/tmp/es6"中的./app/index.js"@多 ./app/index.js

  6. 运行 mkdir app &&touch app/index.js(在linux中，创建文件夹'app'，然后在app文件夹内创建index.js文件)

  7. 重新运行 npm run build 并成功:

Although the error refers to a missing script build, i have placed a 'build' script in my package.json

{
  "name": "es6",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^3.8.1"
  }

}

and this is my webpack.config.js file

module.exports = {
  entry: ['./app/index.js'],
  output: {
    path: './build',
    filename: 'bundle.js'

  }
}

Can anyone tell me how to fix this error or where it is coming from. I am new to using node.js, webpack and the command line. Thanks in advance for your time!

解决方案

  1. Try setting the output.path in webpack.config.js to an absolute path

    module.exports = {
    entry: ['./app/index.js'],
    output: {
        path: __dirname + '/build',
        filename: 'bundle.js'
    }
}

    I don't have Windows (on Linux) but with node 8.16.0 and npm 6.4.1, replicating your package.json and webpack.config.js, I got the following error:

    Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.output.path: The provided value "./build" is not an absolute path!
    -> The output directory as **absolute path** (required).

    See more on the absolute-path stuff here

  2. Since you are on Windows, check your file line-endings (CRLF vs LF). If you've cloned code from another place, depending on your git config, it might have carried over different line endings. You can quickly check line endings in the lower-right corner of VSCode.

Steps I did to mimic your setup:

  1. copied your package.json and webpack.config.js
  2. run npm i (or npm install)
  3. run npm run build - received the invalid configuration error noted above
  4. changed the output.path to an absolute path concatenating with __dirname (not sure if Windows is different...)
  5. reran npm run build and got: 

    ERROR in multi ./app/index.js
Module not found: Error: Can't resolve './app/index.js' in '/tmp/es6'
@ multi ./app/index.js

  6. ran mkdir app && touch app/index.js (in linux, creates folder 'app' and then creates the index.js file inside the app folder)

  7. reran npm run build and success:

    > es6@1.0.0 build /tmp/es6
> webpack
