Vue项目运行报错 TypeError: Cannot read properties of undefined (reading ‘upgrade‘)

npm run dev运行Vue项目后报错TypeError: Cannot read properties of undefined (reading ‘upgrade’)，尝试删除node_modules及package-lock.json后均不起作用，后排查发现

vue.config.js中路径出了问题

proxy: {
      '/api': {
        target: process.env.VUE_APP_BASE_URL, // .env 文件配置
        changeOrigin: true,
        pathRewrite: { '^/api': '' }
      },
      
      }

添加了.env.development文件

ENV = 'development'
VUE_APP_BASE_API = '/api'
VUE_APP_BASE_URL='http://localhost:8080'

再次运行项目成功运行
