我遵循了你推荐的一切,让 Babel 7 与 Jest 一起工作。
我安装了@babel/core
和 babel-core
.还是不行。
{
"devDependencies": {
"@babel/cli": "^7.0.0-beta.51",
"@babel/core": "^7.0.0-beta.51",
"@babel/node": "^7.0.0-beta.51",
"@babel/plugin-transform-modules-commonjs": "^7.0.0-beta.51",
"@babel/preset-flow": "^7.0.0-beta.51",
"babel-core": "^7.0.0-beta.51",
"jest-cli": "^23.1.0"
}
}
后
yarn jest
yarn run v1.9.0-20180612.1255
$ /Users/m/Desktop/k/node_modules/.bin/jest
FAIL packages/services/src/Client/__tests__/Client.js
- Test suite failed to run
Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

最佳答案
在 Jest GitHub 问题上看到您的问题——我认为是您提出的问题,但我最终通过 create-react-app
repo 解决了这个问题。并了解他们如何整合 Jest。具体来说, packages/react-scripts/package.json
文件有你需要的东西。
"@babel/core": "7.0.0-beta.46",
"@babel/runtime": "7.0.0-beta.46",
"autoprefixer": "8.5.0",
+ "babel-core": "7.0.0-bridge.0",
"babel-eslint": "8.2.3",
"babel-jest": "22.4.3",
添加带有 +
的行,或更改您拥有的版本,您应该会很好。
