ruby - compass 安装在 WebSpace : Command not found

Question

我想在托管服务器上的我的网站空间中使用 Compass(无根访问权限)。我遵循了托管公司提供的教程，但到目前为止没有成功:

在我的主目录中，我创建了一个 .gem 目录和一个 .gemrc 文件:

/* .gemrc in home dir */

gemhome: &GemHome /my/home/dir/.gem
gempath:
   - *GemHome
   - /usr/lib/ruby/gems/1.8

.bashrc 文件:

export GEM_HOME=/my/home/dir/.gem
export GEM_PATH=/my/home/dir/.gem:/usr/lib/ruby/gems/1.8

重新连接后的一些检查:

[~] echo $GEM_HOME
/my/home/dir/.gem

[~] echo $GEM_PATH
/my/home/dir/.gem:/usr/lib/ruby/gems/1.8

[~] echo $PATH
?/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

安装 compass

[~] gem install compass

Successfully installed compass-core-1.0.3
Successfully installed compass-import-once-1.0.5

Successfully installed rb-fsevent-0.9.6

检查安装

[~] gem list compass -d

    Speed up your Sass compilation by making @import only import each
    file once.


[~] gem which compass
/my/home/dir/.gem/gems/compass-1.0.3/lib/compass.rb

但是不能使用 compass :

[~] compass
-bash: compass: command not found

知道我还需要做什么才能让 compass 运行吗？我发现了关于该主题的其他几个讨论，但所有解决方案都针对具有根访问权限的服务器。由于我没有服务器的根访问权限:还有其他解决方案吗？

-bash: compass: command not found

Answer 1

您的 .gem 位置没有附加到您的环境变量中。从输出 echo $PATH 可以看出，它没有附加到您的 $PATH 环境变量。

尝试将其附加到您的 $PATH 变量

export GEM_HOME=/my/home/dir/.gem/bin
export GEM_PATH=/my/home/dir/.gem:/usr/lib/ruby/gems/1.8

PATH=$PATH:GEM_HOME:GEM_PATH
export PATH

最后做一个source ~/.bashrc

更新

将正确的可执行文件路径附加到 $PATH 环境变量将使您的可执行文件在 shell 环境中可用。

在此特定场景中，可执行文件位置为 /my/home/dir/.gem/bin
