I am using a raspberry, I did update it too. But it didn't work. These are the dependencies installed.

• javascript
• raspberry-pi
• node-gyp
• epoll
• electron-rebuild

In my case, after updating NodeJS to version 17.0.1, the same problems started.

The whole problem was in the bcrypt package, it no longer meets the standards of version 17

In my case, reduced the version to 16 helped.

electron-rebuild v3.2.5 released.

The problem was solved after updating!

gyp: name 'openssl_fips' is not defined while evaluating condition 'openssl_fips != ""' in binding.gyp while trying to load binding.gyp

I just spent my day solving this. Eventually, here's what has worked for me.

• install the latest node-gyp locally:

  npm install -d node-gyp@latest
  

• in binding.gyp, add (at the top):

  {
      "variables": {
          "openssl_fips" : "0" 
      },
  
      ...      
  }
  

I have a same problem too, but i am using a serialport not epoll.

So, I think the cause of this problem is electron modules not the native module.

yarn run v1.22.15
$ electron-rebuild -f -w myapp

This problem started yesterday. There were no problems in the last week.

I already installed the windows-build-tools, node-gyp, python 3.x.

I set the npm config & yarn config & python Env path, msvs_version too.

I reinstalled above packages many many times but not work electron-rebuild.

That is whole Error messages. There is no more Error messages.

What should we do?

I use a PowerShell script based on @noseratio's answer.

    $path = ".\node_modules\@nodert-win10-rs4\windows.devices.geolocation\binding.gyp"

    $content = Get-Content $path
    $content = $content -replace '"USE_ADDITIONAL_WINMD": "true"', '"USE_ADDITIONAL_WINMD": "true", "openssl_fips": ""'
    $content | Set-Content $path -Encoding Ascii
