javascript - 从 npm 安装插件会导致错误

Question

我正在使用 Ionic v2 开发 Visual Studio 2017，我正在尝试编写一个扫描信标的应用程序。但是每次我安装插件时，我都会从 npm 收到有关 Node 和 npm 本身版本的错误。我当前的版本:

Cordova version: 7.0.1
Npm version: 5.0.3
Node version: 8.1.3

例如，我安装了 cordova 蓝牙插件，这就是我收到的错误:

    npm ERR! node v5.4.1
    npm ERR! npm  v3.3.4
    npm ERR! code ELIFECYCLE
    npm ERR! io.cordova.myappd95ddb@ build: `ionic-app-scripts build`
    npm ERR! Exit status 1
    npm ERR! 
    npm ERR! Failed at the io.cordova.myappd95ddb@ build script 'ionic-app-
             scripts build'.
    npm ERR! This is most likely a problem with the io.cordova.myappd95ddb 
             package,
    npm ERR! not with npm itself.

我在互联网上查了一下，但显然没有很多与蓝牙配合使用的更新插件，这是否意味着我必须降级我的 Node 和 npm 版本？你知道我可以使用任何其他插件吗？

这样解决:在Vs中打开Tools/Options/Project and Solution/External Web Package。将 $PATH 移至 ../external 之上。
