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

Commencez par reproduire ns migrate --log trace avec les versions de CLI et de runtime indiquées. Examinez nativescript/lib/common/child-process.js, où l’échec du processus npm est signalé, puis identifiez ce qui provoque l’arrêt de l’installation Android avec le code 1 ; le travail est terminé lorsque la migration s’achève correctement.
