the custom theme will be removed

[ngo]

I copied a theme from persona, then rename it (include some value in .json file).

The issue caused -- When I install or unstall pugin (eg. nodebb-plugin-custom-pages), the custom theme will be removed(in other words, the theme reverted to the 4 main theme).

The custom theme is under the path: /nodebb/node_modules

Is there any mistake I maked?

We recommend not doing this, and rather using a child theme. That's not your problem though.

The custom theme is under the path: /nodebb/node_modules

Place your theme somewhere else and then link it into node_modules using npm

cd path/to/nodebb-theme-your-theme
npm link
cd path/to/nodebb
npm link nodebb-theme-your-theme

@pitaj Thanks!
I put the custom theme outside, and linked it. The custom theme have not be removed , but the link will still lost when I install or unstall a pugin

Yeah it's a known issue you'll have to relink sometimes. It depends on what npm version and OS you're using.
