Your current build command is “npm; npm run build”. The command “npm” is not a valid build command as it does not do anything in particular. This means that it will not install any packages or run any scripts, so it is not a useful command for building a project.
To build a project, you should use the command “npm install” which will install all the necessary packages first. You may also want to add “npm run build” or any other build command after that.
