Saving shared material shader code library failed for IOS

When I tried to deploy the project to iPhone, I got such an error. Could someone help me? Thanks!!!

OVERVIEW: LLVM Archiver (llvm-ar)
  This program archives bitcode files into single libraries
USAGE: llvm-ar [options] [relpos] [count] <archive-file> [members]...
OPTIONS:
  -M                                -
  -format                           - Archive format to create
    =default                        -   default
    =gnu                            -   gnu
    =darwin                         -   darwin
    =bsd                            -   bsd
  -plugin=<string>                  - plugin (ignored for compatibility
  -help                             - Display available options
  -version                          - Display the version of this program
OPERATIONS:
  d[NsS]       - delete file(s) from the archive
  m[abiSs]     - move file(s) in the archive
  p[kN]        - print file(s) found in the archive
  q[ufsS]      - quick append file(s) to the archive
  r[abfiuRsS]  - replace or insert file(s) into the archive
  t            - display contents of archive
  x[No]        - extract file(s) from the archive
MODIFIERS (operation specific):
  [a] - put file(s) after [relpos]
  [b] - put file(s) before [relpos] (same as [i])
  [D] - use zero for timestamps and uids/gids (default)
  [i] - put file(s) before [relpos] (same as [b])
  [o] - preserve original dates
  [s] - create an archive index (cf. ranlib)
  [S] - do not build a symbol table
  [T] - create a thin archive
  [u] - update only files newer than archive contents
  [U] - use actual timestamps and uids/gids
MODIFIERS (generic):
  [c] - do not warn if the library had to be created
  [v] - be verbose about actions taken

It Occurred to me too.

There are Chinese characters in my project path, so I zip the project and change its path with no space and only English words, then problem solved.
