Cygwin：安装指南针后指南针命令不起作用

Question

I use cygwin64 on windows. I have installed compass using the command

gem install compass

and have got the result:

Successfully installed compass-1.0.3
Parsing documentation for compass-1.0.3
Done installing documentation for compass after 1 seconds
1 gem installed

But when I try to use the command compass , it says the command doesn't exist.

There is a difference in the installation from cygwin compared to when I do it in CMD, where it works. If I do

gem install compass

from cmd, I get a different kind of installation including 8 gems:

C:\Windows\System32>gem install compass

So , shouldn't this installation be the same for cygwin? I see on the compass page on rubygems.org rubygems.org/gems/compass that some "Runtime Dependencies" are listed - so maybe that explains it? So cygwin doesn't download the dependencies, and I have to do it manually?

The big question is, why isn't compass available as a cygwin installer package?

By the way, ruby has been installed from the cygwin installer packages, and sass is installed, and working.

There is a compass file in two places:

C:\cygwin64\home\(my username)\bin\compass
C:\cygwin64\home\(my username)\.gem\ruby\gems\compass-1.0.3\bin\compass

but it isn't even looking for this file when I try to run compass command.

Update:

I installed these gems: chunky_png multi_json compass-core compass-import-once rb-fsevent ffi rb-inotify

and now when I run compass it looks for the file, but says:

C:\Ruby22\bin\ruby.exe: No such file or directory -- /cygdrive/c/Ruby22/bin/compass (LoadError)

which is a step in the right direction. But it looks for it in the windows installation of ruby, not the cygwin installation.

this command which -a compass gives:

/cygdrive/c/Ruby22/bin/compass
/cygdrive/c/Ruby22/bin/compass

^this is supposed to be usr\\bin\\gem I think..

I had a similar problem. Be careful that you don't get confused between the Ruby instance you may have installed on your Windows and the Cygwin Ruby. You need to add the Ruby bin directory to your PATH. Here's how I did it (after I installed sass with gem):

$ sass
-bash: sass: command not found

$ vi .bashrc

$ tail -2 .bashrc

export PATH=$PATH:/home/luca/bin/

$ source .bashrc

$ sass -v
Sass 3.4.23 (Selective Steve)
