ns migrate (to 8) failing at Android step

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.0.2
• Cross-platform modules:
• Android Runtime: 7.0.1
• iOS Runtime: 6.5.4
• XCode Version: 12.5.1
• Plugin(s): none

Describe the bug

spawn: npm "install" "--legacy-peer-deps" "tns-android@8.0.0" "--silent" "--dev" "--save-dev" "--save-exact"
Will send the following information to Google Analytics: {
  type: 'googleAnalyticsData',
  category: 'CLI',
  googleAnalyticsDataType: 'event',
  action: 'Performance',
  label: 'PackageManager__install',
  customDimensions: { cd2: 'Angular', cd9: 'false', cd5: 'CLI' },
  value: 10877
}
Error: Command npm failed with exit code 1
    at ChildProcess.<anonymous> (/usr/local/lib/node_modules/nativescript/lib/common/child-process.js:143:36)
    at ChildProcess.emit (events.js:315:20)
    at maybeClose (internal/child_process.js:1048:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:288:5)

To Reproduce

ns migrate --log trace

Expected behavior
Succesful migration

報告されている CLI と runtime のバージョンで ns migrate --log trace を再現することから始めます。npm プロセスの失敗が報告される nativescript/lib/common/child-process.js を調査し、Android のインストールがコード 1 で終了する原因を特定してください。移行が正常に完了すれば完了です。
