按element-ui官网的步骤进行按需引入，报错：Error: Cannot find module ‘babel-preset-es2015’
npm install babel-plugin-component -D
然后添加.babelrc文件
{
"presets": [["es2015", { "modules": false }]],
"plugins": [
[
"component",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
这样做之后疯狂报错
由于没有.babelrc文件可以在babel.config.js中安装配置
npm i @babel/preset-env -D
并且，也不再使用es2015，改成@babel/preset-env
module.exports = {
presets: [
'@vue/cli-plugin-babel/preset',
["@babel/preset-env", { "modules": false }]
],
"plugins": [
[
"component",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
}
如果刷新之后还是报错的话，就重新跑一下项目.
