[1.7.1-beta.25] Error: Cannot find module '@babel/runtime/helpers/builtin/interopRequireDefault

[rj-david]

When I first run beta.25, I got this error message:

Unable to resolve some modules:

  "@babel/runtime/helpers/builtin/interopRequireDefault" in /home/rj/Projects/Bountee/imports/ui/navigations/AppNavigator.jsx (web.browser)
  "@babel/runtime/helpers/builtin/extends" in /home/rj/Projects/Bountee/imports/ui/navigations/AppNavigator.jsx (web.browser)

If you notice problems related to these missing modules, consider running:

  meteor npm install --save @babel/runtime

My package.json had this after running the package install command above

"dependencies": {
        "@babel/runtime": "^7.0.0-beta.56",

Then I got this error:

I deleted .local and run meteor npm update and now I'm getting both errors above

[rj-david]

The error happened when using this version:

"@babel/runtime": "^7.0.0-beta.56"

There is no problem with version 7.0.0-beta.55

The folder @babel/runtime/helpers/builtin was missing in beta.56

[benjamn]

Right, you should stay on @babel/runtime@7.0.0-beta.55 until you can update to Meteor 1.7.1-beta.27 (coming soon).

This error was the result of a deliberate breaking change in the runtime-related Babel 7.0.0-beta.56 packages (@babel/runtime, @babel/plugin-transform-runtime, @babel/runtime-corejs2): babel/babel#8266

Removing the dependency on core-js is a big step in the right direction, but also a pretty big disruption between beta versions. I'm glad they did this before the final Babel 7 release.

[benjamn]

Ok, this should work if you update to the latest Meteor 1.7.1 beta and also update @babel/runtime:

meteor update --release 1.7.1-beta.27
meteor npm install @babel/runtime@latest

Please feel free to reopen if the same problem still happens!

[scottstensland]

just started to get this on my builds using

meteor 1.7.0.3

even after issuing meteor npm install @babel/runtime@latest

[benjamn]

@scottstensland @babel/runtime@7.0.0-beta.55 is what you want if you’re still on 1.7.0.3. The @babel/runtime@latest version is appropriate only after you’ve updated to the latest Meteor 1.7.1 beta.

[rj-david]

@benjamn, is it possible to make some announcement related to this? Many meteor developers were getting stuck since yesterday. I'm not sure if the existing topics in the forum will suffice. Also considering that we are not yet in RC for 1.7.1 and not to be released anytime soon.

[benjamn]

I'm going to reopen this issue so that people can find it more easily when they come to report similar problems.

We could publish a new patch version of the Meteor babel-runtime package that complains if you install @babel/runtime@7.0.0-beta.56, but then folks would have to update babel-runtime before they saw the warning.

[josechavezm]

I'm having a similar error after updating to 1.8.
It says that I should install @babel/runtime but I already did it, as suggested by the migration steps

[MHerszak]

@hiei189 same here. I am having problems, too. Updating to the latest version of babel doesn't help at the moment. Any suggestions?

[josechavezm]

@MHerszak using @babel/runtime@7.0.0-beta.55 works fine. I'm still getting the warning though.

[linegel]

I'm on 1.7.0.3 and project not builds even with 7.0.0-beta.55
UPDATE:
7.1.2 works fine with 1.8

[miguelconde91]

I have Meteor 1.7.0.5, with 7.0.0-beta.55 and not work.
