Problems with npm installation package dependencies

A strange problem occurs when using npm to install package dependencies. Normally, a node_modules directory is generated, and all packages are in the changed directory. I don"t know why, when installing dependent packages, there is a .staging directory in the node_modules directory. All the packages are in this directory. I tried it several times, deleted it, installed it and deleted it again. How to deal with the masking? What is the cause
