mksquashfs file does not exist & chmod - executable file not found in %PATH%

[b5414]

• Electron-Builder Version: 24.9.1

• Node Version: 20.9.0

• Electron Version: 28.1.4
• Electron Type (current, beta, nightly): current

• Target: linux

I'm building on win64 electron app with vite and build cfg in yml, I have seen: https://www.electron.build/cli#targetconfiguration so my options are snap or appimage, I selected snap and I have these errors (probably related to each others)

• cannot execute chmod error=exec: "chmod": executable file not found in %PATH% after built

⨯ cannot execute cause=exec: "C:\\Users\\Yes\\AppData\\Local\\electron-builder\\Cache\\appimage\\appimage-12.0.1\\linux-x64\\mksquashfs": file does not exist

But, if I do: win+r, paste this path, hit enter, then I see mksquashfs file with 264kb size

---

Btw, electron-builder --win --config goes fine, I have the valid installer after it

We use import { chmod } from 'fs-extra' and not from fs package directly, does fs-extra not have compatibility with windows?

I'm experiencing the same error that @b5414 is having.

Electron-Builder Version: 24.9.1 Node Version: 20.11.0 Electron Version: 28.2.1 Electron Type (current, beta, nightly): current Target: linux x64.

I also have mksquashfs with 264kb. Both the Snap and AppImage targets for Linux x64 render this same error.

I do not have 7za.js in my builder-util/out directory. To resole this, I performed a complete reinstall of electron-builder with npm remove electron-builder and npm i electron-builder --save-dev. However, the '7za.js' file is still missing.

I ran C:/myWorkspace/node_modules/builder-util/out dir and got the following output:

Adding the content in a new file called 7za.js and using npx patch-package builder-util yields a mkdir file because I am missing some of the original content in 7za.js.

[mmaietta]

Ah, I was basing off master branch for current code to patch. Can you please try using next version of electron-builder: v24.12.0

[clairejhaas]

I updated electron-builder to v24.12.0, and I am using patch-package v8.0.0. After upgrading, I have the 7za.js file and made the changes suggested. Running npx patch-package electron-builder yields a rmdir error on node:fs:1219 for binding.rmdir(pathModule.toNamespacedPath(path)); The errno is -4082, code EBUSY. However, neither Windows Event Viewer or Task Manager show anything related to the temp file the patch-package created. I also ran this all as administrator, so should have access to the file (AppData/Local/Temp/tmp-####) where the patch info is created.

I have a same problem that @b5414

Well, mksquashfs is Linux ELF executable. It cannot be executed natively on Windows.

Such either a Windows version of mksquashfs is needed (or an alternative command from, e.g., https://github.com/AgentD/squashfs-tools-ng) or it should be executed via WSL (what adds another dependency though).
