Question

我试图从源头制造Sage，但我失败了。似乎Yosemite上缺少库_scproxy。我没有在SO上和网上的任何地方找到非常有用的帮助。如果有人可以帮助我。这是日志：

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the relevant part of the log file
  /Users/sam/Downloads/sage-6.7/logs/pkgs/setuptools-12.4.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/Users/sam/Downloads/sage-6.7/local/var/tmp/sage/build/setuptools-12.4 and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd '/Users/sam/Downloads/sage-6.7/local/var/tmp/sage/build/setuptools-12.4' && '/Users/sam/Downloads/sage-6.7/sage' --sh)
When you are done debugging, you can type "exit" to leave the subshell.

编辑：好的，我不知道发生了什么，但我重新开始建设，这似乎有效。我没有任何gcc。当我输入gcc -v时，有人回答我，我已经铿锵而不是它...当我第一次make时，控制台要求我重命名我的目录opt/local，因为自制。认为这是第一次没有用的东西。我在编辑圣人期间将其重命名为opt/local ......

可能这是因为Python构建（Sage＆＃39，Python）没有成功构建这个模块;见this sage-release thread。原则上http://trac.sagemath.org/ticket/17174应该修复它（参见http://trac.sagemath.org/ticket/17169）但是你可能正在使用非Sage gcc，比如自制软件？在那种情况下，你需要在某个地方制作that change，或者只是使用Sage的gcc，你使用SAGE_INSTALL_GCC=yes（当然，这需要更长的时间）。祝你好运！

ImportError：没有名为_scproxy的模块
