上周我因为bash“易受攻击的问题”而在cygwin上做了更新。
之后我再也无法编译sass了。
我试图重新安装ruby,在一些安装失败后重新安装cygwin我安装了它并更新了“gem update --system”
它运行,但当我尝试安装指南针时,我收到了以下消息:

我尝试安装ffi(“gem install ffi”和“gem install ffi --pre”),我收到同样的消息

这是日志(.gem / ruby​​ / extensions / x86_64-cygwin / ffi-1.9.5 / gem_make.out)

package configuration for libffi is not found

我真的很沮丧!!'

答案 0 :(得分:23)

是的,对我而言,这只是gcc环境,所以你可以试试

sudo apt-get install gcc

在ubuntu中对我有用:)

答案 1 :(得分:4)

确保已安装xcode。

xcode-select --install

如果已安装,请确保您已接受服务条款。

sudo xcodebuild -license

向下滚动到底部并输入同意。

它应该与上述步骤一起使用。

如果您在执行上述两个步骤后发现以下问题

ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/compass

尝试以下。

sudo su
sudo gem install -n /usr/local/bin compass

答案 2 :(得分:2)

在OSX上,这有效:

如果gem install compass失败,请尝试

gem install ffi 如果也失败了,那么错误似乎是ffi构建在/usr/bin中查找gcc-4.2

如果您安装了gcc,只需键入

即可在/usr/bin内创建符号链接

sudo ln -s gcc gcc-4.2

否则您可能需要先安装gcc(google that)

答案 3 :(得分:0)

试试这个:

按照您的ruby版本下载并安装ruby开发套件
