当我尝试安装最新版本的指南针(https://rubygems.org/gems/compass/versions/1.0.0.alpha.17)时,出现以下错误.

这里发生了什么？如何安装最新的指南针而不出错？
试试这个,然后尝试再次安装指南针
apt-get install ruby-dev
为了安装指南针在Mac OS X 10.10(Yosemite)上必须执行以下操作:
1.设置Ruby环境
确保安装ruby并保持最新: ruby -v
更新宝石 sudo gem update --system
2.设置MAC环境
- 安装Xcode命令行工具这是安装Compass的关键.
ruby -v
- 安装Xcode命令行工具是让Compass在OS X上运行的关键
3.安装指南针
sudo gem update --system
最好的方法是sudo apt-get install ruby-compass安装指南针.
你可以尝试使用Debian
sudo apt-get install gcc ruby-dev rubygems compass
对于Fedora,Centos
yum -y install gcc ruby-devel rubygems compass
它对我有用.
我和你在同一个问题上挣扎了大约3个小时.截至Compass 1.0.alpha19,要求是rvm版本1.9.3.
有几个未收集的帖子,但对我有用的是以下内容:
sudo gem uninstall sass
sudo gem uninstall compass
rvm install ruby-1.9.3-p448
sudo gem install sass --pre
sudo gem install compass --pre
这样做了.希望它也适合你!
为了解决这个问题,我必须确保拥有最新版本的Ruby和宝石gem update --system; 然后,我必须确保安装了Xcode和命令行工具:xcode-select --install.
在Mac OS上,您需要安装此功能!
xcode-select --install
嗨,让它在Mac上工作是一个挑战,所以无论如何这里是一个解决方案
安装macports
安装rvm
重启终端
运行rvm requirements然后运行rvm install 2.1
最后一步来运行 gem install compass --pre
我不确定但是Mavericks上的ruby版本不支持本机扩展等...所以如果你指向其他ruby版本,就像我做"2.1"一样,它工作正常.
不知道为什么这些都没有被标记为正确的答案,但我通过谷歌搜索登陆这里,所以我将传递我所知道的...
@ paul_g的方法非常接近我,我在Mac OSx10.9 Retina上的步骤:
安装macports
安装rvm(与Ruby --insecure相关问题的ruby add 标志稳定)$\curl -sSL --insecure https://get.rvm.io | bash -s stable --ruby
重启终端/资源您的个人资料
运行rvm requirements --with-gcc=clang您不必更新Ruby,因为您下载了最后一个稳定版本
最后一步来运行 gem install compass --pre
