    "tailwindcss": "^3.4.1",

  }
}

and per check , there shouldn’t have the lib impact the system, and in the code , I just use the code here below to import the fonts I want, and it works for me, which shouldn’t impact the system fonts,


     import CanvasBuilder from 'canvas';  // import the node-canvas to do some of the draw actions

     .......
     const canvas= CanvasBuilder.createCanvas(width, height);
      // this fonts here below existed and path is correct
     const fontPath = path.join(process.cwd(), 'public/fonts/HostGrotesk-VariableFont_wght.ttf') 
     CanvasBuilder.registerFont(fontPath, { family: 'CustomFont' });   // import the fonts 
     const ctx = canvas.getContext('2d');
     ctx.font = `10px CustomFont,sans-serif,serif`;     // use the fonts
     .........
