VueJS 和 Jest：找不到模块“babel-core”

Question

我正在尝试将 Jest 与 VueJS 一起使用，但是我得到了Cannot find module 'babel-core' at Object.<anonymous> (node_modules/vue-jest/lib/compilers/babel-compiler.js:1:15).

我解决这个问题的唯一方法是添加

"@babel/core": "^7.7.5",
"babel-core": "^7.0.0-beta.47",

然后测试通过，但我不想将“beta”版本保留在我的 package.json 中，并且将@babel/core和放在babel-core一起很奇怪，因为知道它们是不同版本中的相同包。

我看到错误似乎是在 Vue-Jest 中，但它已经在上一个版本中了。

下面是我package.json断掉的电流（没有"babel-core": "^7.0.0-beta.47"）

只需使用babel-bridge。来自github问题

npm install babel-core@^7.0.0-bridge.0 --save-dev
