指南针安装在 WebSpace 上：找不到命令

Question

I want to use Compass in my webspace on a hosted server (no root access). I followed tutorial provided by the hosting company but had no success so far:

In my home dir I created a.gem dir and a.gemrc file:

/* .gemrc in home dir */

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

The.bashrc file:

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

Some checks after re-connecting:

[~] 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

Installing Compass

[~] gem install compass

    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

But Compass cannot be used:

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

Any idea what else I have to do to get compass running? I found several other discussions about this topic but all solutions targeted servers with root access. Since I do not have root access to the server: Any other solutions?

Answer 1

Your .gem location is not appended to your environmental variable. As seen from the output echo $PATH it isn't appended to your $PATH environmental variable.

Try appending it to your $PATH variable

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

Finally do a source ~/.bashrc

Update

Appending the correct executable path to the $PATH environment variable will make your executable available within the shell environment.

In this specific scenario the executable location is /my/home/dir/.gem/bin

Answer 2

I knwow the post is dating, but after passing time to find help on the web, it was the more proach of my pb. And as I past time to find the bin, i found it on openSuse 15.4 under: /usr/lib64/ruby/gems/2.5.0/gems/compass-1.0.3/bin

For that I do before:

find  /usr/lib64/ruby/gems/2.5.0/gems/  -type f | grep compass

then

PATH=$PATH:/usr/lib64/ruby/gems/2.5.0/gems/compass-1.0.3/bin
export PATH

Hope this will be usefull for anybody
