Question

在我运行我的开发脚本时，我的项目目录出错了。我假设这是由于babel转换，但我不知道还有什么可以调试这个问题。我已经删除并重新安装了我的节点模块，重新启动了我的服务器，并确保babel-node位于node_modules目录中。我不明白为什么在项目目录上抛出错误。我的项目结构如下：

/server
 - package.json
 - /node_modules
 - /src
    - server.js
    - /routes
    - /models
    - /controllers
    - /etc....

运行yarn dev

时抛出的错误

➜ yarn dev
yarn run v1.5.1
$ nodemon -w src --exec "babel-node src --presets env,stage-0"
[nodemon] 1.17.2

我重新安装了babel模块并密切关注他们的文档。我不得不将babel-node直接指向server.js文件。

“nodemon -w src --exec babel-node src / server.js --presets env，stage-0”

运行babel脚本时，node.js无法找到模块
