I have tested npm install mypackage@version with registry=http://localhost:8081/repository/npm-group/ But it is not fine :slight_smile: c:\WORKSPACE\PROJECTS\WAMPR\TESTAPI>npm install wampr_api@1.0.0 npm ERR! code E40…

Finally, I can install my package from Nexus because I remove https-proxy from the .npmrc…

I don’t really understand about proxy
