appium: driver installation in appium 2 fails because of appium@2.0.0-beta.41 as peerDependencies

The problem

CI in ruby_linb_core started failing to install drivers since yesterday?: My local installation also started failing with the same error. Something changed? After installing npm -g install @babel/core @babel/cli additionally. but still babel error occurred.

https://dev.azure.com/AppiumCI/Appium CI/_build/results?buildId=22725&view=results is the root CI tasl. https://dev.azure.com/AppiumCI/Appium CI/_build/results?buildId=22711&view=results was ok. This was on Wed 27th 5pm PDT.

I wondered 2.0.0-beta 41 had something initially, but the same error continued with appium@2.0.0-beta.40

part of https://github.com/appium/ruby_lib_core/blob/master/ci-jobs/functional/run_appium.yml:

steps:
- task: NodeTool@0
  inputs:
    versionSpec: 16.x
  displayName: Install Node 16.x to get NPM v8
- script: npm install -g appium@${APPIUM_VERSION}
  displayName: Install appium beta
- script: npm install -g mjpeg-consumer
  displayName: Install MJPEG Consumer
- script: npm list --depth 2 -g || echo 'ok'
  displayName: Installed node dependencies
- script: appium driver install ${APPIUM_DRIVER}
  displayName: Install appium driver ${APPIUM_DRIVER}
  env:
    APPIUM_HOME: $(Agent.HomeDirectory)/appium

I haven’t tried NodeJS 14 and npmv6, so potentially the combination only can work.

Environment

• Appium version (or git revision) that exhibits the issue: ?? maybe 2.0.0-beta.41 release or related??
• Last Appium version that did not exhibit the issue (if applicable):
• Desktop OS/version used to run Appium: macOS, Linux
• Node.js version (unless using Appium.app|exe): nodejs 16, npm v8.
• Npm or Yarn package manager: npm
• Mobile platform/version under test:
• Real device or emulator/simulator:
• Appium CLI or Appium.app|exe:

Details
