When I try to publish a new package to npm or try to logout, I get the following error message:
npm ERR! code E426
npm ERR! 426 Upgrade Required
CodePudding user response：
Beginning October 4, 2021, all connections to npm websites and the npm registry—including for package installation—must use TLS 1.2 or higher.
What I did:
- upgrade Node (0) to its current recommended version: 14.18.0 LTS
- upgrade npm with
npm install -g npm@latest
In my case, I had to manually set the registry to use https instead of http as well:
npm config set registry https://registry.npmjs.org/
(0) When using nvm, that's what you need to do:
nvm install 14.18.0
nvm use 14.18.0
nvm alias default 14.18.0

Robin Wieruch was right, this problem confused me today
