找不到模块“babel-core”但安装了@babel/core

Question

运行jest测试后，其中之一出现此错误。

Cannot find module 'babel-core'

      at Object.<anonymous> (node_modules/vue-jest/lib/compilers/babel-compiler.js:1:15)

这很简单。未安装 babel-core。但是安装了更新版本的 babel-core (@babel/core)！

在这里我添加我的 package.json devDependencies

"devDependencies": {
    "@babel/core": "^7.4.5",
    "@babel/preset-env": "^7.4.5",
    "@babel/runtime": "^7.4.4",
    "@vue/cli-plugin-babel": "^3.7.0",
    "@vue/cli-plugin-eslint": "^3.7.0",
    "@vue/cli-plugin-pwa": "^3.7.0",
    "@vue/cli-service": "^3.7.0",
    "@vue/test-utils": "^1.0.0-beta.29",
    "axios-mock-adapter": "^1.16.0",
    "babel-eslint": "^10.0.1",
    "babel-loader": "^8.0.6",
    "babel-preset-env": "^1.7.0",
    "bootstrap": "^4.3.1",
    "eslint": "^5.8.0",
    "eslint-plugin-vue": "^5.0.0",
    "gulp-babel": "^8.0.0",
    "jest": "^24.8.0",
    "jest-serializer-vue": "^2.0.2",
    "jest-transform-stub": "^2.0.0",
    "jest-watch-typeahead": "^0.3.1",
    "json-loader": "^0.5.7",
    "less-loader": "^4.1.0",
    "postcss-flexbugs-fixes": "^4.1.0",
    "postcss-loader": "^3.0.0",
    "raw-loader": "^2.0.0",
    "sw-precache-webpack-plugin": "^0.11.5",
    "vue-jest": "^3.0.4",
    "vue-loader": "^15.7.0",
    "vue-template-compiler": "^2.5.21",
    "webpack": "^4.32.0",
    "webpack-cli": "^3.3.2"
  },

我想知道如何让我的 babel loader 或 jest 识别 @babel/core 而不是 babel-core。我读到 babel-loader 8+ 应该可以完成这项工作，但它没有按预期工作。

不知道这是一个 vue-jest 问题，但谢谢。

babel-core不是@babel/core——它们是不同的包。

你应该可以离开这里

• 安装babel-core桥，
• 或切换到vue-jest使用@babel/core.
