Javascript “需要巴别塔”^7.0.0-0“；，但却充满了",；6.26.0“；

我已经将我的应用程序迁移到了babel 7 beta版，除了测试之外，一切都正常。我想我已经读过了所有的东西，但是我仍然得到了这个错误：

● 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

生成过程中的某些内容正在加载错误的版本。 检查此错误的堆栈跟踪以查找第一个条目 这并没有提到“@babel/core”或“babel-core”来看看是什么 呼叫巴贝尔

在我的例子中，结果证明我是通过

npmi-D babel jest

显式安装这个包的。你需要同时拥有

babel core@^7

和

@babel/core@^7

以及

babel-jest@latest

，请尝试添加

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

正如这里提到的
