Question

在我的Rails 6项目中，我用

添加了jQuery pushMenu

添加纱线推送菜单

来自https://www.npmjs.com/package/push-menu 现在，我可以在node-modules文件夹中看到它，为推菜单。但是，当我尝试从包中导入或包含包时，如：

require("push-menu")

我收到以下错误：

Uncaught Error: Cannot find module 'push-menu'
at webpackMissingModule (application.js:12)
at Module../app/javascript/packs/application.js (application.js:12)
at __webpack_require__ (bootstrap:19)
at bootstrap:83
at bootstrap:83

我的package.json文件看起来像这样

//package.json file
{
"name": "example_setup",
"private": true,
"dependencies": {
"@rails/actioncable": "^6.0.0-alpha",
"@rails/activestorage": "^6.0.0-alpha",
"@rails/ujs": "^6.0.0-alpha",
"@rails/webpacker": "^4.0.7",
"jquery": "^3.4.1",
"push-menu": "^2.0.8",
"select2": "^4.0.7",
"turbolinks": "^5.2.0"
},
"version": "0.1.0",
"devDependencies": {
"webpack-dev-server": "^3.7.1"
}
}

我在这里做什么错了？

看起来推送菜单模块坏了：

它定义了一个“app/index.js”作为主索引文件：

{
  "name": "push-menu",
  "version": "2.0.8",
  ...
  "main": "app/index.js",
}

但是在 node_modules 文件夹中没有 node_modules/app/index.js

尝试像这样导入它：

import from 'push-menu/src/js/jquery.pushMenu'

Rails 6 Webpacker找不到已安装模块的模块
