javascript - npm installation dependencies are always incomplete

Question

Pull a project from github, and after npm install, you often encounter this problem when starting npm run dev

Cannot find module '...模块名...'

Go into the corresponding module dependency package and see that they are all soft link directories, and the soft link directory is an invalid directory and does not have the corresponding resource package, that is, it is not installed.
