can not use 'package-delete' to remove entirely

[earthIsAPrisonIfYouNotAwareItCanNotOut]

something confuse me a lot
when I use package-delete to delete skewer-mode, skewer-less and simple-http packages
then I restart and every packages I delete above are reinstalled
is there any dependency I have not deleted?

I've never used package-delete, so I don't know what might be happening. There should be nothing in my own packages that would interfere with package-delete, though. Perhaps you tried deleting them in the wrong order? You should start with skewer-less, then skewer-mode, then simple-httpd. According to the MELPA website, all of these packages depend on skewer-mode, so make sure you don't have any installed: * ac-js2 * ein * livid-mode * skewer-less * skewer-reload-stylesheets * trident-mode https://melpa.org/#/skewer-mode

is it possible I opening a httpd server and the server is closed incorrectly, so the cache file lead to reinstall all the packages?
