when I use sudo, this can be solved in shell ,but I can't use :ErlangTags as there is no sudo in vim. what's the reason?

It seems that you have a directory that vim-erlang-tags tries to read, but for which your user doesn't have read privileges.

When you call :ErlangTags, your currrent directory should be the directory that contains your Erlang files, not / or $HOME for example. Is there a reason for having this directory which cannot be read by your user?
