vue 前端框架构建踩坑记录（自用）_npm warn ebadengine unsupported engine { npm warn

进入前端模块根目录下执行构建命令：

npm run build:prod
1

由于没有安装依赖包，所以提示如下：

> osap-system-ui@4.4.0 build:prod
> vue-cli-service build

'vue-cli-service' 不是内部或外部命令，也不是可运行的程序或批处理文件。

怀疑可能是 npm 版本低的原因，查看版本：

npm -v
7.9.0

更新 npm 版本：

npm install -g npm

使用淘宝镜像重新安装依赖：

npm install --registry=https://registry.npm.taobao.org
1

安装淘宝的 cnpm：

npm install -g cnpm --registry=https://registry.npm.taobao.org
1

使用 cnpm 进行构建则成功：

cnpm run build:prod
