loadPartialConfig() throws Cannot destructure property showIgnoredFiles of 'undefined' or 'null' on v7.12.0

vue 项目构建报错

项目之前是好的, 但是最近构建报错, 如下:

TypeError: Cannot destructure property `showIgnoredFiles` of 'undefined' or 'null'.
TypeError: Cannot destructure property `showIgnoredFiles` of 'undefined' or 'null'
     at Function.<anonymous>  (/Users/luo/WorkSpace/company/alarm/node_modules/@babel/core/lib/config/partial.js:132:7)

经过排查, 发现是 @babel/core 最新的版本 ^7.x.x 版本中发布了不兼容的变更
根据语义话版本号的描述, ^7.x.x 版本的发布应该是兼容性功能增强, 但是因为 API 的变更导致以前直接使用 babel.loadPartialConfig() 的库会报错, 比如项目使用了 @vue/cli-plugin-babel@4.1.1, 他的实现如下

这一切的问题是因为 babel 并没有安装 samver 语义话版本造成, 期待对 loadPartialConfig 做一下兼容修复, 重新发布版本

为什么 github v7.12.1 上面的源码已经修复了这个问题, https://github.com/babel/babel/blob/v7.12.1/packages/babel-core/src/config/partial.js#L73-L81, 但是在 npm 上的 v7.12.1 的包上代码没有更改 😪

I reverted the commit that introduced the regression and released it as @babel/parser@7.12.2.

@nicolo-ribaudo @babel/parser@7.12.2 When to publish to npm

[nicolo-ribaudo]

We only release updated packages, so only @babel/parser in this case (and not @babel/core showed in your screenshot).
You can use npm --depth 9999 update @babel/parser to update it.

Sorry my mistake, this isn't fixed yet. I'll prepare a PR; as a workaround you can pass {} to loadPartialConfig({}).

@nicolo-ribaudo I can't change it, because that vue/cli-plugin-babel call loadPartialConfig (), you can see the issue description above.
And, https://github.com/babel/babel/blob/v7.12.1/packages/babel-core/src/config/partial.js#L73-L81 has modifed, only not publish to npm

[nicolo-ribaudo]

Fixed in 7.12.3!
