我正在尝试使用npm在我的Windows系统上安装node-xmpp-core。
（我曾尝试使用cygwin，但是在配置时，node-gyp不会干净地退出。）
我正在使用标准的Windows cmd提示符。我的命令是：
> npm install node-xmpp-core --msvs_version=2013
我得到的错误是“.. \ node-stringprep.cc（2）：致命错误C1083：无法打开包含文件：'unicode / unistr.h'：没有这样的文件或目录”。 （下面的完整输出。）
由于我知道编译器必须查找此文件，因此我下载了ICU库并设置了INCLUDE环境变量：
> set INCLUDE
INCLUDE="C:\Program Files (x86)\icu\include"
发生了什么事？
我从多个网络搜索中了解到，在SO和其他地方，Windows上涉及node-gyp的所有内容都可能很脆弱。但这似乎是如此基本。
完整的gyp输出（也有基本的npm输出）：
> node-stringprep@0.5.4 install C:\Users\jgruenhu\My Documents\code\centenario\jxgProj\node_modules\node-xmpp-core\node_modules\node-stringprep
> node-gyp rebuild
