我不是JSMaven，所以这个问题可能有一个简单的解决方案。我正在尝试.Net Core Angular SPA模板。当我尝试运行npm install命令时，它卡在extract:zone.js步骤上。下面是命令输出。

D:\Projects\UI>cd ClientApp

D:\Projects\UI\ClientApp>npm install
[       ...........] / extract:zone.js: verb lock using C:\Users\rahul\AppData\Roaming\npm-cache\_locks\staging-f4d27da8ef6cdab8.lock for D:\Projects\UI\ClientApp\node_modules\.staging

我尝试重新安装node和npm，但似乎没有什么区别。这是我的node和npm版本。

D:\Projects\UI\ClientApp>npm version
{ AngularMaterial: '0.0.0',
  npm: '6.4.1',
  ares: '1.14.0',
  cldr: '33.1',
  http_parser: '2.8.0',
  icu: '62.1',
  modules: '64',
  napi: '3',
  nghttp2: '1.34.0',
  node: '10.12.0',
  openssl: '1.1.0i',
  tz: '2018e',
  unicode: '11.0',
  uv: '1.23.2',
  v8: '6.8.275.32-node.35',
  zlib: '1.2.11' }

我没有添加或删除默认的.net core Angular SPA模板中的任何内容。感谢帮助。

更多详细信息以下是我已经尝试过的命令。

运行带有-ddd标志的命令会生成类似的输出，最后几步看起来像这样。下面是完整日志的pastebin：https://pastebin.com/gnvn1wHe
