1、npm publish之后，老是报错
2、如下图
3、npm ERR! code E403npm ERR! 403 403 Forbidden - PUT https://registry.npmjs.org/learnnode - You do not have permission to publish "learnnode". Are you logged in as the correct user?npm ERR! 403 In most cases, you or one of your dependencies are requestingnpm ERR! 403 a package version that is forbidden by your security policy.npm ERR!

4、在网上查了一下资料，原来是package.json里面的包名在npm上已经存在，所以要修改一下
5、重新上传就成功了
