Question

我是一个新手nodejs。我在将nodejs应用程序部署到谷歌应用程序引擎时遇到了麻烦。这是我的错误，我一直试图解决它，但它不起作用。我已经安装了babel。

错误

更新服务[默认] ...失败   错误：（gcloud.app.deploy）错误响应：[9]   应用程序启动错误：

restaurant_api@1.0.0 prestart / app   npm run -s build

您错误地安装了babel包，这是Babel 6中的无操作。   Babel的CLI命令已从babel包移至babel-cli包。

npm uninstall babel

npm install --save-dev babel-cli

这是我的package.json

Answer 1

问题很简单，如果你清楚地注意到GAE，就不会安装dev-dependencies。所以把你的设备移到deps里面，就像我做的那样，babel没有发现错误消失了。

Answer 2

线索在错误消息中。

在你的devDependencies部分，你已经包含了babel-cli。但是，您的依赖项部分仍然引用"babel": "^6.23.0"。

要么删除这一行，要么用babel-cli替换它，留下你：

"dependencies": {
  "babel-cli": "^6.23.0",
  "body-parser": "^1.17.0",
  "express": "^4.15.0",
  "express-jwt": "^5.1.0",
  "jsonwebtoken": "^7.3.0",
  "mongoose": "^4.8.5",
  "passport": "^0.3.2",
  "passport-local": "^1.0.0",
  "passport-local-mongoose": "^4.0.0",
  "pm2": "^2.4.2"
},

Answer 3

你需要全局安装babel-cli，即运行命令＆＃34; npm install babel-cli -g＆＃34;作为构建npm脚本的一部分，或创建一个安装它的安装脚本，如果你想让它更有条理，以防你以后需要添加更多东西。

"scripts": {
"dev": "NODE_ENV=development nodemon -w src --exec \"babel-node src --presets es2015,stage-0\"",
"build": "npm install bable-cli -g && babel src -s -D -d dist --presets es2015,stage-0",
