Hi. Can you please follow these steps:

• Add core-js@2
• Ensure no .babelrc or babel.config.js or babel config in nuxt.config exists
• Remove yarn.lock / package-lock.json and resintall

Hello pi0!
I have same issue on 2.6.1 version
This is little bit weird if core-js@2 is dependence of nuxt.js and users will need to add them manually, don't you?

[pi0]

@ivandata It is a dependency of nuxt indeed! But will be hoisted by yarn/npm if some other dependency requires core-js@3. Adding to top-level package.json prevents this.

More explained in 2.6.0 notes.

[ivandata]

got it, thank you!

yarn add core-js
如果还不行
删除 node_modules,然后使用 yarn 安装，不要使用 cnpm 安装；

@pi0 is the recommendation to still use corejs 2 with it being deprecated? If so what are the reasons for the strong recommendation in that changelog?

Thanks!
