npm ERR! registry error parsing json

Question

I am working on a small Cordova v4.0.0 project, npm version: v0.10.35 I was adding some plugins, normally, until now, when I try to add another plugin, it gives an error:

cordova plugin add org.apache.cordova.NetworkManager
Fetching plugin "org.apache.cordova.NetworkManager" via plugin registry
npm ERR! registry error parsing json
npm ERR! registry error parsing json
SyntaxError: Unexpected token I
Internal routing error

In my attempt to solve this, I did:

npm cache clean

I had some proxy, installed by a spyware, that I uninstalled. I already cleared windows proxy settings, and npm proxy settings:

npm config rm proxy
npm config rm https-proxy

But it stills not working.

Alternative solution is to use git:

cordova plugin add https://github.com/apache/cordova-plugin-network-information

.

Fetching plugin "https://github.com/apache/cordova-plugin-network-information" via git clone
Installing "org.apache.cordova.network-information" for android
Installing "org.apache.cordova.network-information" for windows

Answer 1

The server isn't responding. For the time being, you can install most of the plugins from GitHub like this:

cordova plugin add https://github.com/apache/cordova-plugin-network-information

or

cordova plugin add https://github.com/apache/cordova-plugin-statusbar.git

Be aware, it is possible side effects may occur due to dependencies between plugins and differences in versions that would have to be solved on a case by case basis. Let's hope this isn't a chronic problem.
