Error publishing a new version of a package in npm
I also had the same problem. for me the email was not verified. You can login on npmjs.org and verify the email.
I don't know, What happen in your code during installation package. Please check here : https://docs.npmjs.com/getting-started/creating-node-modules to take a look how to install package modules. These are simple way to install package :
Publish your package to npm
Make a new directory outside of your project and cd into it
Run npm install <package>
Create a test.js file which requires the package and calls the method
Run node test.js. The message should be output.
#To publish on npm registry
You need to create npm user. You can follow here. In short
npm adduser
npm login
Do npm config ls
to ensure that credentials are stored on your client.
Then try
npm publish
.
To install it locally OR test packaging your module
You can try
tar -tf $(npm pack)
npm install <path/to/your/package.tgz>
