Ruby Compass编译器无法正常工作，错误在线[54]

Question

Ruby Compass无法正常工作，代码如下，我在网上尝试了10-20种方法，有什么建议吗？

在屏幕截图中，您将找到一种更简单的方式来阅读我的宝石的终端转储和错误，如果您想从那里取一些东西，您将在屏幕截图下找到该文本

谢谢， 干杯， 罗伯特

Answer 1

通过安装以下指南针扩展程序修复：

gem install compass-normalize
gem install compass-rgbapng
gem install toolkit

Answer 2

这对我没有解决。但是，我能够通过使用

重新安装指南针宝石来解决它

gem uninstall compass
gem install compass

我认为只需使用gem update compass将指南针宝石更新到最新版本，就可以更轻松地修复它。

注意：如果您使用rails，则可能还需要更新compass-rails gem。否则，compass watch命令将开始挂起。见issue on github
