【中文标题】Rails 6 webpacker找不到已安装模块的模块【英文标题】:Rails 6 webpacker cannot find module for installed module 【发布时间】:2019-10-30 21:35:08 【问题描述】:在我的 Rails 6 项目中,我添加了带有
的 jQuery pushMenu纱线添加推送菜单
来自https://www.npmjs.com/package/push-menu 现在我可以在 node-modules 文件夹中看到它,作为推送菜单。但是,当我尝试从包中导入或包含时,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"
我在这里做错了什么?
【问题讨论】:
您能检查一下node_modules/push-menu
文件夹是否存在吗?
【参考方案1】:
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'
