我按照你建议的一切步骤来让 Babel 7 能够与 Jest 配合使用。我安装了 @babel/core
和 babel-core
,但它仍然无法工作。
{
"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"
}
}
在运行
yarn jest
命令后: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.
