macOS Catalina doesn't support 32-bit executables and as result Wine cannot run Windows 32-bit applications too

Prerequisites

• Using yarn
• Using node 10.x
• Using an up-to-date master branch
• Using latest version of devtools. See wiki for howto update
• Link to stacktrace in a Gist (for bugs): https://gist.github.com/arnaudambro/1e026d23f55f5851b0c28a7d0a285c7f

Expected Behavior

yarn package-all does not end with ERR_ELECTRON_BUILDER_CANNOT_EXECUTE

Current Behavior

yarn package-all end ERR_ELECTRON_BUILDER_CANNOT_EXECUTE (cf full stacktrace here The dmg and zip packages are created but the app inside is not working. But the ./release/mac/ElectronReact.app is working. I couldn’t test for Windows.

Context - Your Environment

I don’t know if it happens in all Catalina’s mac, but I would think so.

I solved this by changing the windows build config on package.json:

  "win": {
      "target": [
        {
          "target": "nsis",
          "arch": [
            "x64"
          ]
        }
      ]
    },

No. One solution is to downgrade the macOS version that you’re using in CI. Apple is officially has officially dropped support for 32 bit executables.
