需要Babel "^7.0.0-0"，但在react(xml-解析器包)上加载了"6.26.3“，已经尝试了所有当前的解决方案。

Question

在这个问题上，我已经尝试过很多由Github社区给出的解决方案，但似乎没有一个对我有帮助。

/node_modules/react-xml-parser/dist/bundle.js:需要Babel "^7.0.0-0"，但是加载了"6.26.3“。如果您确信您有一个兼容版本的@babel/core，那么您的构建过程中可能会有什么东西加载错误的版本。检查此错误的堆栈跟踪，以查找没有提到"@ Babel /core“或"babel-core”的第一个条目，以查看调用Babel的内容。(同时处理预置："/Users/Brenor2/Documents/Freelas/ReiDasLiganetes/proj_ecommerce_reidasliganetes/mstore-expo/node_modules/@babel/preset-env/lib/index.js")

下面是包react-xml-解析器的.babelrc文件，它引发错误(我必须手动将文件从"env“更改为”预设-env“)：

{ "presets": ["@babel/preset-env"] }

Answer 1

最后，我解决了我的问题，将react xml解析器(导致错误的包)降级为较旧的版本，并且工作正常。这是有意义的，因为这个错误是在我对所有包进行更新后开始的。

Answer 2

babel-plugin-transform-decorators-legacy是给Babel 6的。

相反，使用@babel/plugin-proposal-decorators并更新您的.babelrc

{
  "plugins": [
    ["@babel/plugin-proposal-decorators", { "legacy": true }],
  ]
}

Answer 3

https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy

您需要将["@babel/plugin-proposal-decorators", { "legacy": true }]与babel7结合使用。

大多数用于babel7的包都从babel-whatever-*重命名为@babel/whatever-*
