安裝gem'scrapi'時出錯

Question

我使用rubyinstaller安裝了Ruby 1.9.3。

我執行： gem install scrapi

我得到以下內容：

Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/ffi-1.0.1
1 for inspection.
Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/ffi-1.0.11/ext/ffi_c/gem_m
ake.out

gem_make.out文件包含以下荒謬信息：

C:/Ruby193/bin/ruby.exe extconf.rb
checking for ffi.h... no
checking for ffi.h in /usr/local/include... no
checking for rb_thread_blocking_region()... yes
checking for ruby_native_thread_p()... yes
checking for rb_thread_call_with_gvl()... yes
creating extconf.h
creating Makefile

make
libffi.gnu.mk:24: *** target pattern contains no `%'.  Stop.

有任何想法嗎 ？
