Solved, So nice!!! @vweevers you are right. It can’t find the native module. But I should set external in electron builder rather than webpack config.

// vue.config.js
module.exports = {
  configureWebpack: {
  },
  pluginOptions: {
    electronBuilder: {
      externals: ['level'],
    },
  },
};

I has been stuck for 2 days. After I saw this thread, I solved the problem! Remind who came this thread, I’m using https://github.com/pouchdb/pouchdb which also depend on “leveldown”. And, solve by adding this in webpack config externals: { leveldown: 'leveldown', },
