Ruby 安装sass 3.3的预发行版gem失败（sass需要侦听（~>；0.7））

由于添加了sourcemap支持，我正在尝试安装sass（3.3）的预发布版本，但由于以下错误而失败：

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: sass requires listen (~> 0.7)

WARNING: vendor/listen doesn't exist, and this isn't a git repository so I can't get it automatically!
chmod -R a+rx bin
rake aborted!
Command failed with status (127): [chmod -R a+rx bin...]
C:/Users/xxx/sass-master/Rakefile:44:in `block in <top (required)>'
Tasks: TOP => install => package => permissions
(See full trace by running task with --trace)

ERROR:  Error installing sass:
    sass requires listen (~> 0.7, runtime)

我使用了以下命令：

gem install sass --pre

直到现在，我已经安装了sass v3.2.8。在安装预版本之前卸载此版本没有帮助

有什么想法吗

还有一件事：我也想过直接从git存储库安装它，但我不知道从哪个分支可以获得预版本

我也在sass git存储库的问题跟踪程序上发布了这个问题：

编辑： 我刚刚尝试使用“rake install”从git hub安装主分支，但这给了我以下错误：

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: sass requires listen (~> 0.7)

WARNING: vendor/listen doesn't exist, and this isn't a git repository so I can't get it automatically!

警告：供应商/listen不存在，而且这不是git存储库，因此我无法自动获取它！
chmod-R a+接收箱
雷克流产了！
命令失败，状态为（127）：[chmod-ra+rx bin…]

（通过使用--trace运行任务查看完整跟踪）

毫无疑问，预发行版存在问题。也就是说，我使用

gem-install-sass-version=3.3.0.alpha.184

成功地使它工作。如果需要指南针，请尝试使用v0.12.2

然后你需要用指南针来运行SASS，而不是SASS。例如：

sass --compass --sourcemap styles.scss:styles.css

这里的信息：

我遇到了一个类似的问题（可能是相同的，但语法略有不同），因为我遇到了以下错误：

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: sass requires listen (~> 0.7)

WARNING: vendor/listen doesn't exist, and this isn't a git repository so I can't get it automatically!

ERROR:  Error installing sass:

在尝试了imjared给出的上述答案后，我尝试使用

gem install sass--version=3.3.0.alpha.103

，如本文中终端的屏幕截图所示，请注意终端命令末尾的

.103

和

.184
