Rails-無法在Windows 8.1上安裝rmagick for Paperclip

Question

我在Rails 4.1應用程序中需要paperclip 。 但是我無法在Windows 8.1中安裝rmagick gem

我的機器已經安裝了DevKit和ImageMagick 6.8.9 。 然后，我嘗試使用以下命令安裝rmagick gem：

gem install rmagick --platform=ruby -- --with-opt-dir=C:/ImageMagick-6.8.9-Q16

它顯示“ 無法構建本地gem擴展 ”，並要求我檢查mkmf.log以獲得詳細信息。 這是日志：

"gcc -o conftest -IC:/Ruby193/include/ruby-1.9.1/i386-mingw32 -IC:/Ruby193/include/ruby-1.9.1/ruby/backward -IC:/Ruby193/include/ruby-1.9.1 -I. -IC:/ImageMagick-6.8.9-Q16/include -DFD_SETSIZE=2048  -DFD_SETSIZE=2048  -O3 -fno-omit-frame-pointer -g -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration conftest.c  -L. -LC:/Ruby193/lib -LC:/ImageMagick-6.8.9-Q16/lib -L.    -lCORE_RL_magick_ -lX11  -lmsvcrt-ruby191  -lshell32 -lws2_32 -limagehlp -lshlwapi  "

6: {
7:   return 0;

/* end */

嘗試搜索該錯誤，但未找到任何內容。

注意事項 ：

這是我收到的第一個完整錯誤消息：

您不需要rmagick gem即可運行Paperclip。 您只需要在系統上安裝ImageMagick。 從您的Gemfile中刪除rmagick。
