Question

前段时间我在项目中使用了webpack，当我必须更新项目前端，并从package.json运行脚本时，我得到以下错误，所以我不能做任何事情：

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
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! sh@1.0.0 surveiller: `webpack --watch`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the sh@1.0.0 surveiller script.
npm ERR! This is probably not a problem with npm. There is likely 
additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you 
mean to install?

我之前已经使用过这个脚本并且运行良好。如果你能帮助我，那对我来说将是一个很大的安慰。

感谢您的帮助

Answer 1

仅当您安装了webpack 4.*时才会发生这种情况，那里有webpack 3。

尝试升级到webpack 4。由于webpack和webpack-cli被拆分为不同的包，因此可以使用。

Answer 2

日志回答你的问题： - ＆GT;使用npm时：npm install webpack-cli -D - ＆GT;使用纱线时：纱线添加webpack-cli -D

使用npm或yarn安装它。

显然有一个包已经分开了两个。

Webpack package.json没有运行
