Nuxt 2.15.x部署到Azure提示找不到@nuxt/ufo模块问题求助

我正在将Nuxt应用部署到Azure，近期已升级到最新版Nuxt，项目在本地运行正常，但部署到Azure时收到如下报错：

我了解到@nuxt/ufo模块在Nuxt 2.15.x版本中已被移除，我已执行rm -r -d *清空Azure应用wwwroot文件夹下的所有文件，再通过Visual Studio Code执行全新部署。

部署日志如下：

我不清楚既然该模块已被移除，为什么部署后仍提示需要该依赖，本地可正常运行的项目中也不存在@nuxt/ufo文件夹。
package.json配置如下：

"scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "generate": "nuxt generate",
    "lint:js": "eslint --ext .js,.vue --ignore-path .gitignore . --fix",
    "lint": "npm run lint:js"
  },
  "dependencies": {
    "@microsoft/signalr": "^5.0.5",
    "@nuxtjs/auth-next": "^5.0.0-1610642462.1bcdc1e",

    "eslint-plugin-vue": "^8.1.1",
    "sass-loader": "^10.1.1",
    "webpack": "^4.46.0"
  }

请问还有什么排查方向或者可尝试的解决方案？

更新1 #

我已将这个已废弃的包添加到package.json文件中重新部署，这也暴露出了底层问题：站点实际运行的仍是旧版本内容，但在KUDO中可以看到新代码已经部署成功。我停止Azure中的站点后，站点确实无法访问，可以确认我操作的是正确的应用实例。这也能解释@nuxt/ufo相关报错的原因：站点运行的仍是依赖该废弃模块的Nuxt 1.14.6版本旧代码。

解决方案 #

• 清理全量缓存：进入Kudu控制台的Debug控制台，先删除/home/site/wwwroot下所有文件，再删除/home/site/deployments下所有历史部署记录，重启应用服务后重新执行全量部署，不要使用增量部署。
• 调整启动配置：进入Azure门户对应应用服务的「配置」-「常规设置」，确认启动命令设置为npm run start，避免硬编码的旧版本启动路径被调用。
• 启用包直接运行模式：在应用服务的「配置」-「应用程序设置」中添加环境变量WEBSITE_RUN_FROM_PACKAGE，值设为1，该配置会让Azure直接从你上传的部署包运行代码，完全绕过本地文件缓存，避免旧代码被加载，配置后重启服务生效。
• 确认构建产物正确性：本地解压你上传的部署zip包，随机打开.nuxt目录下的js文件搜索是否存在@nuxt/ufo引用，确认本地构建的产物是正确的新版本，避免将旧的构建包上传部署。
• 重新安装依赖：如果你的依赖是在Azure端自动安装的，删除/home/site/wwwroot/node_modules目录后手动执行npm install重新安装依赖，再启动服务。
