Question

我正在尝试从Babel 6-> 7升级。我使用npx babel-upgrade --write来协助更新package.json，然后运行了npm install。

尝试运行我们的webpack开发服务器时，它无法编译并出现以下错误：

ERROR in ./src/app/index.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Cannot find module 'babel-plugin-transform-object-rest-spread' from '/vagrant'

    at alias (/vagrant/node_modules/@babel/core/lib/config/config-descriptors.js:63:49)

注意/vagrant是项目的根。

babel-plugin-transform-object-rest-spread中仅剩下node_modules的引用，所以我猜这些是不是以某种方式触发了它？

编辑：我无法确定问题的原因，并且已恢复为Babel 6。

有这个问题，经过一些挖掘后能够解决它-

我们的 webpack 配置和 transform-object-rest-spread 中的插件中仍然有一个 package.json，没有 babel 前缀。用 @babel/plugin-proposal-object-rest-spread 替换它为我们修复了它！

Babel错误：“错误：无法从'/ vagrant'找到模块'babel-plugin-transform-object-rest-spread'”
