如何用节点js和babel保存正确的行号
我有以下设置，并有我的错误/堆栈跟踪问题，我错过了什么？
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';
我的堆栈跟踪是疯狂的

正如你所看到的，这看起来不正确，很难遵循。 我相信有办法解决这个问题。
看起来你错过了'bugsnag'模块。 尝试：
npm install -g bugsnag
