ns migrate (to 8) failing at Android step

首先使用报告中的 CLI 和 runtime 版本重现 ns migrate --log trace。检查报告 npm 进程失败的 nativescript/lib/common/child-process.js，然后确定导致 Android 安装以代码 1 退出的原因；迁移成功完成即表示完成。

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 maybeClose (internal/child_process.js:1048:16)

To Reproduce

ns migrate --log trace

Expected behavior
Succesful migration
