node.js - Babel 并将 Nodejs 部署到 Google App Engine

Question

我是一个nodejs新手。我在将 Nodejs 应用程序部署到 google 应用程序引擎时遇到问题。这是我的错误，我一直在尝试修复它，但它不起作用。我已经安装了 babel。

错误

Updating service [default]...failed.
ERROR: (gcloud.app.deploy) Error Response: [9] Application startup error:

restaurant_api@1.0.0 prestart /app npm run -s build

You have mistakenly installed the babel package, which is a no-op in Babel 6. Babel's CLI commands have been moved from the babel package to the babel-cli package.

npm uninstall babel

npm install --save-dev babel-cli

这是我的 package.json

Answer 1

问题很简单，如果你明显注意到GAE，没有安装dev-dependencies。因此，将您的 dev-deps 移至 deps 内部上方，就像我所做的那样，并且 babel nofound 错误消失了。
