Cannot find module './node_natives/@serialport/bindings-cpp.native.cjs'

I tried this plugin but the built app throw the following error:

Uncaught Exception:
Error: Cannot find module './node_natives/@serialport/bindings-cpp.native.cjs'
Require stack:

Any help is appreciated

No file named @serialport/bindings-cpp.native.cjs is generated

[kingyue737]

I found the cause. My config was native({}). But I just found webpack and forceCopyIfUnbuilt cannot be omitted here while the documentation says that forceCopyIfUnbuilt is true by default.

native({ forceCopyIfUnbuilt: true, webpack: {} })

But now comes another issue, the generated path in bindings-cpp.native.cjs is very strange:

// This is a native module that cannot be built correctly.
module.exports = require("../D:\Solutions\rho-meter\dist-electron\node_natives\node_modules\@serialport\bindings-cpp");

It seems to be a "relative-absolute" path and the backslash \ in the path will cause error on windows.

Found a workaround without this plugin.

1. Tell Rollup to ignore dynamic require

build: [
      {
        vite: {
          plugins: isDev ? [notBundle()] : undefined,
          build: {
            minify: isProd,
+           commonjsOptions: {
+            ignoreDynamicRequires: true,
+         },
            lib: {
              entry: 'electron/main.ts',
              fileName: 'main',
              formats: ['cjs'],
            },
          },
        },
      },
]

2. Copy the required .node file to bundle via electron-builder

   {
   "$schema": "node_modules/app-builder-lib/scheme.json",
   "asar": true,
   "directories": {
   "output": "release/${version}"
   },
   "files": [
   "dist-electron",
   ".output/**/*",
   "!node_modules/**/*"
   ],
   "electronLanguages": ["zh-CN"],
   "win": {
   "icon": "dist/favicon.ico",
   +  "files": [
   +    {
   +        "from": "node_modules/@serialport/bindings-cpp/prebuilds/win32-x64",
   +        "to": "prebuilds/win32-x64"
   +    }
   +   ],
   "target": [
     {
       "target": "nsis",
       "arch": ["x64"]
     }
   ]
   },
   }
