当我试图安装最新版本的compass (https://rubygems.org/gems/compass/versions/1.0.0.alpha.17)时,我得到以下错误。

ERROR:  Error installing compass:

这是怎么回事?如何正确安装最新的指南针?


当前回答

最好的方法是sudo apt-get install ruby-compass来安装指南针。

其他回答

我在Linux Mint上也有同样的问题,但我能够通过卸载ruby并重新安装来修复它。

ruby:卸载

sudo apt-get remove ruby

它报告了一些ruby包,比如:

Package 'ruby' is not installed, so not removed
The following packages were automatically installed and are no longer required:
libruby2.2 ruby-chunky-png ruby-sass rubygems-integration
Use 'apt-get autoremove' to remove them.

卸载剩余软件包*

apt-get autoremove

重新安装ruby

sudo apt-get install ruby2.2

安装指南针

sudo gem install compass

最后一条命令执行成功。

我为你这个问题纠结了大约3个小时。从Compass 1.0开始。Alpha19,需求是RVM版本1.9.3。

有几个未收集的帖子,但对我有用的是以下几点:

Sudo gem卸载sass 须藤宝石卸载罗盘 RVM安装ruby-1.9.3-p448 Sudo gem安装sass—pre Sudo宝石安装指南针-pre

这样就成功了。希望它也适用于你!

嗨,这是一个挑战,让它在Mac上工作,所以不管怎样,这里有一个解决方案

安装macports 安装区 重启终端 先执行rvm requirements命令,再执行rvm install 2.1命令 最后一步是运行gem install compass—pre

我不确定,但是Mavericks上的ruby版本不支持本地扩展等等…所以如果你指向其他ruby版本,比如我做的“2.1”,它可以正常工作。

试试这个,然后再试着安装指南针

apt-get install ruby-dev

你可能需要安装苹果的命令行工具,默认情况下可能没有安装在你的系统上。我得到了同样的错误,但在遵循这里的任何说明之前,我安装了命令行工具(由于一个不相关的问题),当我再次尝试时,指南针安装没有问题。YMMV。
