The file import input suggestion in the Vue project failed after element-plus was installed

After installing element-plus in the Vue project, the input suggestion of file import in the project was wrong, everything was fine before installation, but when I wrote the file after installation, the code suggestion for importing other modules was missing, for example: import {} from 'vue', there is no prompt when typing in {}, but the rest of the code prompts are normal, I wonder why
