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

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。

其他回答

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!

不知道为什么这些都没有被标记为正确答案,但我是通过谷歌搜索登陆这里的,所以我会把我知道的传递下去……

@paul_g的方法对我来说非常接近,我在Mac osx10.9 Retina上的步骤:

安装macports 安装rvm(稳定与ruby添加-不安全标志SSL相关的问题)$\curl -sSL -不安全https://get.rvm.io | bash -s稳定——ruby 重新启动终端/资源配置文件 运行rvm requirements——with-gcc=clang你不需要更新Ruby,因为你下载了最新的稳定版本 最后一步是运行gem install compass—pre

对于macOS 10.14 Mojave,确保您已经通过xcode-select——install安装了命令行工具,并运行以下命令来安装std头文件。

sudo open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

现在再试一下你的指令。

在优胜美地,你所要做的就是安装命令行工具。这样就有用了。

即使其他宝石安装好了。你必须运行xcode-select——install来安装gem compass。

祝你好运。

在Mac OS X 10.9上,如果你尝试xcode-select——install,你会得到以下错误:

无法安装该软件,因为它当前不可用 软件更新服务器。

解决方案是直接从苹果网站https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-下载命令行工具(OS X 10.9)

然后,您将能够安装命令行工具的最新版本。
