您的构建过程中的某些内容加载了错误的版本

Question

我收到以下错误。想不出解决办法。我发现很多帖子在这里看起来是重复的，但是没有任何效果。

喜欢：需要 Babel "7.0.0-0" 但加载了 "6.26.3"

node_modules@babel\helper-plugin-utils\lib\index.js

抛出 Object.assign（错误，{

错误：需要 Babel "^7.0.0-0"，但加载了 "6.26.3"。如果你确定你有一个兼容版本的@babel/core，很可能是你的构建过程中加载了错误的版本。检查此错误的堆栈跟踪以查找未提及“@babel/core”或“babel-core”的第一个条目，以查看调用 Babel 的内容。

以下是我的 package.json

我正在使用 npm start。

找到了 ：-）

我注意到这babel-node不在您的依赖项中，因此您必须使用 的全局版本babel-node，可能是版本 6...因此，只需将正确的添加到您的devDependencies：

npm install --save-dev @babel/node
