找不到错误命令“ encore”。 （独立的后端Webpack）

Question

目录结构

admin/ -> backend webpack
  js/
  .yarnrc
  webpack.config.js
  package.json
assets/ -> frond webpack

admin /文件内容：

.yarnrc

--modules-folder node_modules_admin

这可以正确创建admin / node_modules_admin 管理员使用boostrap 3，前端使用boostrap 4，因此需要单独的文件夹。

webpack.config.js

var Encore = require('@symfony/webpack-encore');

Encore
    // the project directory where compiled assets will be stored
    .setOutputPath('./../public/admin/')
    // the public path used by the web server to access the previous directory

    .enableSourceMaps(!Encore.isProduction())
    .enableVersioning(Encore.isProduction())

        'jquery',
        'bootstrap',
        // 'fullcalendar',
        './js/vendor.js',
        // you can also extract CSS - this will create a 'vendor.css' file
        // this CSS will *not* be included in page1.css or page2.css anymore
        // 'bootstrap-sass/assets/stylesheets/_bootstrap.scss'
    ])

    .addEntry('js/admin', './js/admin.js')
    .addEntry('js/datatables', './js/datatables.js')

    .autoProvidejQuery()
    .autoProvideVariables({

        jQuery: "jquery",
        'window.jQuery': 'jquery',

    })
    // .enableVersioning()
    .enableLessLoader()
    // .addLoader(
    //     {test: require.resolve('signature_pad'), loader: 'expose?SignaturePad'},
    // )
    .enableBuildNotifications()

    // .addLoader(

                //the images will be emmited to public/assets/images/ folder
                //the images will be put in the DOM <style> tag as eg. background: url(assets/images/image.png);
            }
        })

;

let config = Encore.getWebpackConfig();

我进入管理目录

~/PhpstormProjects/vista_bralion_docker/admin$ yarn install
yarn install v1.12.1
[1/4] Resolving packages...
success Already up-to-date.

尝试生成文件

~/PhpstormProjects/vista_bralion_docker/admin$ yarn run encore dev --watch 
yarn run v1.12.1
error Command "encore" not found.

我尝试直接运行安可

这是admin / yarn.lock

Answer 1

对我来说，解决方案是执行以下命令：

$ yarn add --dev vue vue-loader@15.x vue-template-compiler

这是结果：

然后一切正常

其他可能的解决方法是：

• 如果有的话，删除node_modules目录和yarn.lock文件
• 之后： yarn run --ignore-engines

我在带有数字海洋的云路中使用它
