我正在尝试在rails上安装并尝试新项目，但我甚至无法为此错误创建新项目。 mkmf.log文件显示：
"gcc -o conftest.exe -IC:/RailsInstaller/Ruby2.3.0/include/ruby-2.3.0/i386-mingw32 -IC:/RailsInstaller/Ruby2.3.0/include/ruby-2.3.0/ruby/backward -IC:/RailsInstaller/Ruby2.3.0/include/ruby-2.3.0 -I. -DFD_SETSIZE=2048 -D_WIN32_WINNT=0x0501 -D__MINGW_USE_VC2005_COMPAT -D_FILE_OFFSET_BITS=64 -O3 -fno-omit-frame-pointer -fno-fast-math -g -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration -Wdeprecated-declarations -Wno-packed-bitfield-compat conftest.c -L. -LC:/RailsInstaller/Ruby2.3.0/lib -L. -lmsvcrt-ruby230 -lshell32 -lws2_32 -liphlpapi -limagehlp -lshlwapi "
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: #include <winsock2.h>
4: #include <windows.h>
5: int main(int argc, char **argv)
6: {
7: return 0;
8: }
/* end */
请帮忙......
