javascript - 由于找不到 @babel/runtime，从 1.6.0.1 更新到我的 meteor 应用程序 1.6.1 失败

Question

我在win 10上从1.6.0.1更新到meteor 1.6.1。然后我将meteor应用程序更新到1.6.1。看起来一切顺利。但是当我运行该应用程序时，系统会提示我安装@babel/runtime。

当我尝试安装它时，出现此错误

c:\meteor\myapp>meteor npm install --save @babel/runtime
npm ERR! code E404

即将退回到 1.6.0.1，但希望理想地解决此问题。

最终恢复到1.6.0.1版本。我的应用程序再次运行。将来可能会不情愿地升级:–((

更新 npm 模块还需要做一些工作，@babel/runtime 就是其中之一。

The babel-runtime npm package has been required for all Meteor applications since Meteor 1.3. With Babel 7, babel-runtime has been renamed to @babel/runtime. If you update to Meteor 1.6.1 without adding @babel/runtime to your package.json dependencies, the Meteor babel-runtime package will throw a helpful error that recommends running meteor npm install @babel/runtime. You should follow this advice!

This change of names is in fact pretty convenient, because it allows @babel/runtime to be installed alongside babel-runtime, in case you need both for some reason; for example, if you rely on a custom Babel plugin that still assumes babel-runtime is installed.

Most Meteor developers should be able to remove babel-runtime after adding @babel/runtime, though there’s no harm in leaving it installed, since none of its modules will be bundled unless they’re used.
