之后,我不能编译sass了.
我尝试重新安装 ruby,一些安装失败并重新安装cygwin我安装它并更新了“宝石更新 – 系统”
它运行,但是当我试图安装指南针我得到以下消息：

我试图安装ffi(“gem install ffi”和“gem install ffi –pre”),我得到了相同的消息
这里是log(.gem / ruby / extensions / x86_64-cygwin / ffi-1.9.5 / gem_make.out)
package configuration for libffi is not found
"gcc -o conftest.exe -I/usr/include/ruby-2.0.0 -I/usr/include/ruby-2.0.0/ruby/backward -I/usr/include/ruby-2.0.0 -I. -ggdb -O2 -pipe -Wimplicit-function-declaration conftest.c -L. -L/usr/lib -L. -fstack-protector -lruby200 -lpthread -lrt -ldl -lcrypt "
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: int main(int argc,char **argv)
4: {
5: return 0;
6: }
/* end */
我真的很沮丧!!
系统Windows 7 64位
Cygwin的
解决方法
是的,对我来说只是gcc环境,所以你可以试试
sudo apt-get install gcc
这对我在ubuntu
