> I find the root cause from the docs: [https://pip.pypa.io/en/stable/news/] ,
> I think it's because the `–prefix` option is only supported since pip v8.0.
> In flink build docs, there are no description about the pip version, so I
> think here we can use the `--install-option="–prefix=xxx"` for better
> compatibility.
