cannot find module electron updater

[deco-dev]

I encountered cannot find module electron updater error.

• Electron-Builder Version: 22.11.7

• Node Version: 14.17.4

• Electron Version: 12.0.9
• Electron Type (current, beta, nightly):

  electron-updater: 5.2.1

• Target: windows

First I installed electron-updater to dependencies.

"dependencies": {
        "@emotion/react": "^11.8.2",
        "@material-ui/core": "^4.11.3",
        "@material-ui/data-grid": "^4.0.0-alpha.26",
        "@material-ui/icons": "^4.11.2",
        "@material-ui/lab": "^4.0.0-alpha.57",
        "@mui/material": "^5.5.1",
        "@testing-library/jest-dom": "^5.11.10",
        "@testing-library/react": "^11.2.6",
        "@testing-library/user-event": "^12.8.3",
        "@types/jest": "^26.0.22",
        "@types/js-cookie": "^2.2.6",
         ...
        "electron-updater": "^5.2.1",

And I used electron updater to typescript.

import { app, BrowserWindow, ipcMain, dialog } from "electron";
import { autoUpdater } from "electron-updater";

So when I built typescript, There is no error. But I executed the app, the error occurred. So I try to fix some code. This is orignal code. I removed the !node_modules. After that, there is no error.

        "files": [
            "desktop/*",
            "build/**/*",
            "build-desktop/**/*",
            "!node_modules"
        ],

But I don't want to add node_modules because the app size is increased. This is log that gets with tsc --traceResolution option. As you can see the log, when build time, electron-updater is found. But why can not found the module on runtime?

This is my build command.

"desktop-tsc": "tsc desktop/main.ts --skipLibCheck --target es5 --outDir build-desktop --esModuleInterop",

I execute npm run desktop-tsc && electron-builder --win

[deco-dev]

I checked the npm ls --production, it has electron-updater.

You shouldn't explicitly exclude "!node_modules" as that's deliberately blocking the asset from being bundled in the asar. electron-builder should automatically parse your node_modules and only pack the ones that are production dependencies

[KVAnton-WEB]

Did you find a solution? I have a similar problem one with rxjs

[OldManMeta]

The solution I found was to add a postinstall option:

"package": "electron-builder", "postinstall": "electron-builder install-app-deps"
