Npm 持续的笑话错误：需要巴别塔^7.0.0-0“；，但却充满了",；6.26.3“；

每当我使用npm在服务器端安装依赖项时，就会出现一个持久的Jest错误。使用Thread安装相同的依赖项是可行的，但我目前正在一个团队中工作，我们都在使用npm。我已经尝试了所有关于堆栈溢出的建议解决方案，无论是否经过投票，都没有一个对我有效。到目前为止，我问过的两位高级开发人员不认为我在全球安装的npm包中有任何东西会导致这种情况

我运行的每个Jest测试套件都会出现以下错误：

● 测试套件无法运行

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 tolook for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

} }

这是我的.babelrc文件：

{
  "presets": [
   "@babel/preset-env"
  ],
  "plugins": [
    [
      "@babel/plugin-proposal-decorators",
      {
        "decoratorsBeforeExport": true
      }
    ],
    "@babel/plugin-proposal-class-properties"
  ]
}

问题在于jest依赖关系。我也遇到了同样的问题，通过将下面的步骤添加到package.json文件中解决了这个问题

"scripts": {
  ...
  "postinstall": "rimraf node_modules/jest-runtime/node_modules/babel-core node_modules/jest-config/node_modules/babel-core",
  ...  
}

希望这对您有所帮助。

正如前面所说，出现此错误是因为您在项目中使用了Babel 7，而jest仍然使用Babel 6

我也遇到了同样的问题，我通过安装

babel core@^7.0.0-bridge.0

另见：

谢谢你的建议。这在我的情况下不起作用，但我感谢您的帮助。没问题，只要确保您有

rimraf

可用，并且命令运行成功，因为我的环境中也存在此问题：）我将检查它并报告它是否起作用。谢谢！！：）

"scripts": {
  ...
  "postinstall": "rimraf node_modules/jest-runtime/node_modules/babel-core node_modules/jest-config/node_modules/babel-core",
