Vue2.0 installation depends on prompting permission issues

when I ask a question for the first time, I may not be able to describe it clearly. Here"s the thing.

want to do a right-click custom menu function, download a vue-context-menu
from the vue resource and find it is not very suitable. Delete the plugin that you want to install another third-party plug-in.
then prompts the following questions.
originally intended to delete the whole file and redo it, but it prompted that the permission problem could not be deleted, and the permissions were set according to the tutorials on the Internet, etc., but still could not be deleted.
later deleted files with cmd, but all other files were deleted and left a vue-context-menu folder (the one found to be unusable above)
as a rookie used the stupidest way-restart and then that folder can be deleted

but after downloading a vue-mouse-menu and using it, I didn"t feel as good as the last one I planned to delete, and then started this question. No, no, no. How on earth should this be solved? no, no, no. I can"t always restart the deleted ones. Ask the gods for help
