我已将我的应用程序迁移到 babel 7 beta,除了测试之外,一切似乎都正常。我想我已经阅读了所有内容,但我仍然收到此错误:
● Test suite failed to run
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
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.

module.exports = {

我用命令运行它:
"test": "jest --config tests/jest.config.js",
最佳答案
你需要同时拥有 babel-core@^7
和 @babel/core@^7
以及 babel-jest@latest
, 尝试添加
yarn add babel-jest babel-core@^7.0.0-0
关于javascript - 需要 Babel "^7.0.0-0",但加载了 "6.26.0",我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/50620775/
