javascript - 如何使用 Node js 和 babel 保留正确的行号

Question

我有以下设置并且我的错误/堆栈跟踪有问题我是否遗漏了什么？

package.json 看起来像:

{
  "name": "xxxxxx",
  "main": "server.js",
  "private": true,
  "scripts": {
    "start": "nodemon --exec ./node_modules/.bin/babel-node server.js"
  },
  "dependencies": {
    "babel": "^6.5.2",
    "babel-cli": "^6.6.5",
    "babel-preset-es2015": "^6.6.0",
    "babel-preset-react": "^6.5.0",
    "babel-preset-stage-0": "^6.5.0",
    "babel-runtime": "^6.6.1"
  }
}

.babelrc 看起来像:

{
  presets: ["es2015", "stage-0", "react"],
  sourceMap: 'inline',
  retainLines: true
}

server.js 看起来像:

let aVar = '';

throw new Error('some error');
import errorHandler from './app/middlewares/error_handler';

我的堆栈跟踪很疯狂

module.js:341
    throw err;
    ^

如您所见，这看起来不对而且很难理解。我相信有办法解决这个问题。

您似乎缺少“bugsnag”模块。尝试:

npm install -g bugsnag
