MacVim cannot save history

MacVim is unable to save the history. About macVim's inability to save the history, macVim has been debugging macVim on osx for a while, and there are no other problems, that is, saving the history.
No solution, no matter how you set it, you cannot record the search and command line history. The results showed the answers from other people on a website. Then, I checked them carefully and found that the same was true for myself. The problem is that. Check the. viminfo permission. You can find that its owner is root, and other users do not have the permission, so they cannot record it. Processing Method sudo chown username ~ /. Viminfo so that the historical records can be saved smoothly.
