 Replying to [comment:1 ryandesign@…]:
 > The error in #49060 sounds unrelated to the error you're experiencing.
 Rather, your issue sounds like a duplicate of #40998. Does
 /usr/include/malloc.h exist on your system? It should not.

 Yes, the malloc.h is there because previously I make a link to it. Now I'm
 try to delete it in /usr/include, by using both "rm" and "sudo rm",
 however it shows
 {{{
 rm: malloc.h: Operation not permitted
 }}
 Could you help me? Thanks.
