Question

我想在Raspberry Pi上安装Express，因为我想将其用于REST API。问题是我收到以下消息，并且在此站点上找到的所有解决方案均无效。

这是人们在其他线程中询问的一些命令：

npm版本

http_parser: '1.0',
  node: '0.8.21',
  v8: '3.11.10.25',
  ares: '1.7.5-DEV',
  uv: '0.8',
  zlib: '1.2.3',
  openssl: '1.0.0f',
  npm: '1.2.11' }

npm列表

pi@raspberrypi:/usr/local/myapp $ npm list
/usr/local/myapp
└── (empty)

我也试图清除缓存，但是没有任何效果，我被卡住了。谢谢您的帮助。

尝试一下：

Unable to start activity ComponentInfo{...MainActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.net.wifi.rtt.WifiRttManager.isAvailable()' on a null object reference
