electron 报错：Application entry file "background.js" does not exist. Seems like a wrong configuration.

场景

使用 electron-builder ，编写js脚本打包，报错

环境

"electron": "22.0.0",
"electron-builder": "^23.6.0",

相关代码

import * as electronBuilder from "electron-builder";
electronBuilder.build({
        config: {
          directories: {
            output: outputDir,
            app: appPathDir,
          },
          asar: true,
          appId: "com.ikun.app",
          productName: "electron-app",
          nsis: {
            oneClick: false,
            allowToChangeInstallationDirectory: true,
          },
        },
      });

报错

Application entry file "background.js" in the "D:\xxxxx\dist\win-unpacked\resources\app.asar" does not exist. Seems like a wrong configuration.

解决

electronBuilder.build({
        config: {
          directories: {
            output: outputDir,
            app: appPathDir,
          },
          asar: true,
          appId: "com.ikun.app",
          productName: "electron-app",
          nsis: {
            oneClick: false,
            allowToChangeInstallationDirectory: true,
          },
+++   files: ["background.js"],
        },
});

原因

查看app.asar文件里少了background.js的内容
