I try to   npm cache clean    But npm said newer version on npm    5  has self healing Mechanism and every thing i need to do for checking npm is use verify  npm cache verify   npm message    The npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid    If you want to make sure everything is consistent  use  npm cache verify  instead    but for forcing npm use this   npm cache clean --force
