I am having issues installing Cordova and Ionic. At first I couldn't because of what seems to be a corrupted installation, that led me to uninstall NodeJS - Cordova - Ionic.

Now, I've reinstalled NodeJS, without issues but when it comes to the famous line :
npm install -g cordova ionic, I've got this error :
npm ERR! write after end then everytime I try to install cordova ionic, I've got the same error for a different package ...
Here are errors I get :

C:\Windows\System32>npm install -g cordova ionic
npm ERR! write after end

If any of you can help me, it would be very appreciate ;-) Have a nice day...

EDIT 1 : after installing some packages and trying again, I've got this now :

Try installing latest npm version this happens a lot with ionic.

npm install -g npm@latest
npm cache verify
npm i 

If this doesn't work I advise you to switch to yarn. It's faster & easier to use. This is the link to download YARN. After installing just run this command yarn global add cordova ionic

Ionic CLI uses npm by default. So go to your project & run $ yarn install.

If you want Ionic to use yarn by default run this: $ ionic config set -g yarn true


In my case, I didn't downgrade my npm because it will cause chaos in other dependencies. Instead, I tried running

npm cache verify

Error gone...


Let, update the latest version of npm for running this command,

npm install npm@latest -g

Then run this command,

npm install -g cordova ionic
