救命！Requires Babel "^7.0.0-0", but was loaded with "6.26.3".

Question

想通过babel-node让后端node可以运行es6，结果装完babel-cli总是报错Requires Babel "^7.0.0-0", but was loaded with "6.26.3".具体如下：

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

我的package.json配置如下

 "dependencies": {
    "@babel/cli": "^7.2.3",

    "@babel/runtime": "^7.2.0",

    "babel-plugin-transform-decorators-legacy": "^1.3.5",
    "jest": "^23.6.0"
  }

我已经折腾了好几个小时，网上能试的方法都尝试，依然是这个报错！求大神们救命！

Answer 1

把 node_modules 文件夹下的都删了，在重新 npm install 一下

另外，"babel-cli": "^6.26.0" 这行是不是冲突了

要看具体的版本号，可以去 package-lock.json， 或者如果你用了yarn，那就去 yarn-lock.json 中找。

Answer 2

采纳的答案确实说了解决方案，但很模糊，我也遇到了这个问题，花了大半天才搞定，我来解释一下。
不过题主当时为了解决问题，引入了一堆冲突，这种情况首先应该移除所有 babel 相关依赖。
安装 babel-cli 默认安装依赖 babel/core 6.26.3，基本可以说这种不带 @ 的语法将停留在 v6 版本里。
所以要用 v7 的话，就应该使用 @babel/cli,提供 babel 命令行使用环境，这个版本并不会自动安装 @babel/core，而是需要自行安装匹配依赖，所以要能执行 babel，再加上使得 node 能运行 JavaScript 新特性，最小安装为：

yarn add @babel/cli @babel/core @babel/node @babel/preset-env -D

Answer 3

你的依赖中既有babel-cli，也有@babel/cli，既有babel-cor也有@babel/core，可能会引起冲突吧，最好确认下，安装一个就可以了。

Answer 4

1. npm i -g @babel/core @babel/node

运行babel-node通过以下方式

npx babel-node youself.js

Answer 5

我的解决 重装下 babel-loader 之前版本是7.X 重装后8.X 可用
