@vue/cli
是基于Webpack
的打包构建工具,有一些常见的问题…
系列文章:
一、Webpack 相关
待补充…
二、常见问题(@vue/cli
)
1. 第三方依赖包?.
语法,编译时无法解析
详细报错:

解决思路1:升级@vue/cli
版本
$ vue --version # 查看@vue/cli 版本
解决思路2:项目lbsys-front-bh-feature-V4.20.0
中vue.config.js
处理
const transformerFactory = require('ts-import-plugin')
module.exports = {
// ...
chainWebpack: (config) => {
// 处理 node_modules 中的特定文件
config.module
.rule('js-in-node_modules')
.test(/\.js$/)
.include
.add(/node_modules[\\/]@lianpf[\\/]native-sdk/)
.end()
.use('babel-loader')
.loader('babel-loader')
.options({
presets: ['@babel/preset-env'],
})
.end();
// ...
}
}
注意:babel相关版本过低,可能提示需要安装@babel/plugin-proposal-optional-chaining
,此时可选择安装。或者参考如下package.json
中的babel依赖版本:
{
"scripts": {
"build": "babel src -d lib" // 构建命令
},
"devDependencies": {
"@babel/cli": "^7.23.4", // babel 依赖
"@babel/core": "^7.23.5",
"@babel/preset-env": "^7.23.5"
}
}

最后, 希望大家早日实现:成为编程高手的伟大梦想!
