【问题描述】:
运行jest 测试后,其中一个出现此错误。
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)!
我在这里添加我的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-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。
【问题讨论】:
-
@babel/core 和 babel-core 不同
-
我知道,这是不同版本的 babel core。这就是为什么我不明白。为什么它要求 babel-core?而不是@babel/core?
-
Babel 7 不向下兼容 Babel 6。如果你想使用它,你需要将所有相关的依赖升级到 Babel 7 (
@babel/core)。
