使用 webpack 运行 npm release 会导致错误

Question

我正在学习微软的教程： https://docs.microsoft.com/en-us/aspnet/core/tutorials/signalr-typescript-webpack?view=aspnetcore-3.1&tabs=visual-studio

但是当我尝试使用 npm run release 启动程序时，我得到以下控制台输出：

    PS C:\tfs_2020\Developers\User\NetCoreTSWebpack\NetCoreTSWebpack> npm run release                                    
> NetCoreTSWebpack@1.0.0 release C:\tfs_2020\Developers\User\NetCoreTSWebpack\NetCoreTSWebpack
> webpack --mode=production


webpack not installed

Install webpack to start bundling:
  $ npm install --save-dev webpack

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! NetCoreTSWebpack@1.0.0 release: `webpack --mode=production`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the NetCoreTSWebpack@1.0.0 release script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

PS C:\tfs_2020\Developers\User\NetCoreTSWebpack\NetCoreTSWebpack>            

这是我的日志文件：

看起来您可能已经跳过了“配置 Webpack 和 TypeScript”阶段的第 3 步，您需要在该阶段运行以下代码。根据您的输出没有安装 Webpack，应该在第 3 步安装它。

npm i -D -E clean-webpack-plugin@3.0.0 css-loader@3.4.2 html-webpack-plugin@3.2.0 mini-css-extract-plugin@0.9.0 ts-loader@6.2.1 typescript@3.7.5 webpack@4.41.5 webpack-cli@3.3.10
