OSX优胜美地Ruby和指南针问题

Question

I setup Ruby through Homebrew and had Compass and Sass installed on my machine which was running 10.9 (Mavericks). Since I've done the update to 10.10 (Yosemite), when I run grunt serve on my Yeoman project, I get this error:

You need to have Ruby and Compass installed and in your system PATH for this task to work. More info: https://github.com/gruntjs/grunt-contrib-compass Use --force to continue.

Any idea what could have borked this? It worked perfectly before.

UPDATE:

which ruby returns this:

/Users/realph/.rbenv/shims/ruby

$PATH returns this:

-bash: /Users/realph/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin: No such file or directory

I've never really understood the whole $PATH thing, I just remember reading somewhere that it's good to change it from where OSX points it by default. And I decided to go the Homebrew route.

If anyone could help also explain this, I would really appreciate it.

Answer 1

I have this in my bash_profile. I get to it by opening up terminal, then:

nano ~/.bash_profile

Add this to the very top:

export PATH="/usr/local/bin:$PATH"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

To save and exit:

ctrl + x

then

press y to save and hit enter to exit

Close your terminal and reopen then try running your rails commands

If for some reason you do not have a bash profile, create one: http://redfinsolutions.com/blog/creating-bashprofile-your-mac

Answer 2

I follow instructions like this, but it always amuses me...I had followed an earlier tutorial that had slightly different instructions...from gorails...but it didn't quite work then I tried your path method, still no go finally the gem install compass fixed my sitch. (i'm only using compass and not anything else, so there was prob an easier way)

I'm on Yosemite
