需要Babel"^ 7.0.0-0",但加载了"6.26.0"

Question

我已将我的应用程序迁移到babel 7 beta版,除了测试之外,一切似乎都有效.我想我已经阅读了所有内容,但我仍然收到此错误:

●测试套件无法运行

Requires Babel "^7.0.0-0", but was loaded with "6.26.0". If you are sure you have a compatible version of @babel/core, it is likely

您的构建过程中的某些内容正在加载错误的版本.检查这个错误的堆栈跟踪,以寻找没有提到"@通天/芯"或"巴别塔芯",看看有什么在呼唤通天塔中的第一项.

jest.config.js

module.exports = {
  rootDir: '<rootDir>/../../',
  collectCoverageFrom: ['src/**/*.(jsx|js)'],
  moduleNameMapper: {
    '\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$':
      '<rootDir>/tests/fileMock.js',
  },
  setupTestFrameworkScriptFile: '<rootDir>/tests/setupTests.js',
};

我用命令运行它:

"test": "jest --config tests/jest.config.js",

您需要同时拥有babel-core@^7并@babel/core@^7沿babel-jest@latest,尝试添加

yarn add babel-jest babel-core@^7.0.0-0

如https://github.com/facebook/jest/issues/5525中所述
