我有一个node.js应用程序，我想在Ubuntu 20.4服务器上运行，当我尝试运行命令npm install时，我看到以下错误，我在服务器上没有root访问权限，这个问题会在哪里？我有6.14.3版本的npm和14.15.3版本，我该如何处理这个问题？
```
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!
