问题描述
我尝试使用babel和webpack将es6转换为es5，但出现此严重错误。
版本：webpack 4.44.1 时间：2175ms 建于：09/06/2020 00:03:05
./src/api/userApi.js中的错误 模块构建失败（来自./node_modules/babel-loader/lib/index.js）： TypeError：C：\ xampp \ htdocs \ dusk \ src \ api \ userApi.js：无法读取null的属性'bindings' 在Scope.moveBindingTo（C：\ xampp \ htdocs \ dusk \ node_modules @ babel \ traverse \ lib \ scope \ index.js：929：13） 在Blockscoping.updateScopeInfo（C：\ xampp \ htdocs \ dusk \ node_modules \ babel-plugin-transform-es2015-block-scoping \ lib \ index.js：364：17） 在Blockscoping.run（C：\ xampp \ htdocs \ dusk \ node_modules \ babel-plugin-transform-es2015-block-scoping \ lib \ index.js：330：12） 在PluginPass.BlockStatementSwitchStatementProgram（C：\ xampp \ htdocs \ dusk \ node_modules \ babel-plugin-transform-es2015-block-scoping \ lib \ index.js：70：24） 在newFn（C：\ xampp \ htdocs \ dusk \ node_modules @ babel \ traverse \ lib \ visitors.js：175：21） 在NodePath._call（C：\ xampp \ htdocs \ dusk \ node_modules @ babel \ traverse \ lib \ path \ context.js：55：20） 在NodePath.call（C：\ xampp \ htdocs \ dusk \ node_modules @ babel \ traverse \ lib \ path \ context.js：42：17） 在NodePath.visit（C：\ xampp \ htdocs \ dusk \ node_modules @ babel \ traverse \ lib \ path \ context.js：92：31） 在TraversalContext.visitQueue 我｢wdm｣：编译失败。
我真的不确定这里出了什么问题。这是我的package.json。
