Question

我正在通过使用Ruby on Rails和Vue.js开发简单的网站，但是在启动本地服务器时遇到了麻烦。当我在终端 npm run dev 上运行时，它给我2个错误：

 This dependency was not found:
* /Users/muchacho/RoRProjects/crm/crm-vue/node_modules/webpack-dev-server/client/index.js?http://localhost:8080 in multi (webpack)-dev-server/client?http://localhost:8080 (webpack)/hot/dev-server.js ./src/main.js

第二个：

This relative module was not found:
* ./src/main.js in multi (webpack)-dev-server/client?http://localhost:8080 (webpack)/hot/dev-server.js ./src/main.js

我以为缺少一些依赖项或软件包，因此我在终端 npm install 上运行，这给了我另一个错误：

npm ERR! 404 Not Found: @babel/preset-vue@^7.1.0

我尝试安装 @ babel / preset-vue ，但是没有这样的软件包。

我的问题是如何解决此问题，是node.js，vue.js还是npm问题？

如果您需要其他信息或文件-我可以上传源代码。

UPD

这是我的package.json文件：

Answer 1

在我看来，存在Internet连接问题，因此软件包下载不正确。通过重新安装Vue.js和其他软件包解决了问题。

npm ERR！找不到404：@ babel / preset-vue @ ^ 7.1.0
