About comment plugins

[CuteReimu]

It says in vuepress-theme-hope document that we should install comment plugins ourselves by:

npm i -D @waline/client

But I encountered an error in production environment:

Failed to load resource: the server responded with a status of 404 (Not Found)
                                              assets/waline-meta-l0sNRNKZ.js:1 

But everything runs well. And I can use the comment plugins as well.

Should we install the plugins via:

npm i @waline/client

Because I think we may use this plugin in our client?
