[npm] npm ERR! registry error parsing json - While trying to install Cordova for Ionic Framework in Windows 8

I was trying to instal Ionic framework in my Windows 8 system and was trying to install Cordova first.

I'm getting this error while trying to install Cordova, that says

Your environment has been set up for using Node.js 0.12.4 (x64) and npm.

My system configuration is as follows:

C:\Windows\System32>npm -v
2.10.1

C:\Windows\System32>node -v
v0.12.4

C:\Windows\System32>git --version
git version 1.9.4.msysgit.1

I already did

C:\Windows\System32>npm cache clear

before running the install command to no use.

I tried changing the registry to http still no use.

I tried installing Ionic framework separately, still no luck.

I tried installing Phonegap, same errors as above.

I'm just stuck at this point and have no idea what to do.

npm install -g @angular/cli --registry http://registry.npmjs.org/ worked for me

In my case all Internet access must run through a proxy and npm was not configured with the proxy to reach http://registry.npmjs.org.

I ran npm install --log-level verbose to get more information and saw that the response had HTML stating I was not authenticated with the proxy.

Running the following fixed it (replacing below with your username/password/proxy address:

npm config set proxy 'username:[email protected]'
npm config set https-proxy 'username:[email protected]'

I do not advise putting the password in raw text instead using something like cntlm to set up a local proxy that delegates to the real proxy.

I had similar problem. I r?n npm cache clear, closed android SDK manager(which was open before) and re-ran npm install -g cordova and that was enough to solve the problem.

I had this same problem when trying to upgrade pm2 to the latest version.

Thanks to sdm's answer I did npm update npm -g and it did the trick for me.

For me following fixed the issue:

1. npm cache clear
2. Made sure that NPM & Git proxies are set properly

In this case Git proxy may not be required.

I had the same issue and the following fixed my issue:

1. Set the registry: npm config set registry "http://registry.npmjs.org/"
2. Removed the entry in hosts file (using Windows 7) => C:\Windows\System32\drivers\etc\hosts

npm config set registry "http://registry.npmjs.org"

Solved the issue for me. Note that it wouldn't accecpt a forward slash at the end of the url and it had to be entered exactly as shown above.

pls remove the

HTTP_PROXY HTTPS_PROXY proxy from the npmrc file

My npm install worked fine, but I had this problem with npm update. To fix it, I had to run npm cache clean and then npm cache clear.

In my case artifactory was down. npm install command is throwing below error.

npm ERR! registry error parsing json

first I had to delete my registry by using npm config delete registry and register new value using npm config set registry "http://registry.npmjs.org"
