問題描述
找到 SASS 可執行文件的位置。（使用 rbenv） (Find the location of the SASS executable. (using rbenv))
I have a working SASS installation. I can run these commands in terminal and get this output:
sass ‑v
Sass 3.2.9 (Media Mark)
rbenv versions
system
* 1.9.3‑p392 (set by /Users/Eric/.rbenv/version)
2.0.0‑p0
I need to locate the exectuable so that I can provide it to the Webstorm IDE as a file watcher. http://blog.jetbrains.com/webide/2013/03/file‑watchers‑in‑webstormphpstorm‑6‑a‑k‑a‑background‑tasks/. I have set this up in other environments (windows, osx without rbenv) before, but can't figure out how to do it here.
If I run whereis sass, I get no output.
How do I find this executable and specify it for Webstorm?
Digging into rbenv, I see it here: /Users/Eric/.rbenv/versions/1.9.3‑p392/lib/ruby/gems/1.9.1/gems/sass‑3.2.9/bin/sass Specifying this path to webstorm does work. Is it appropriate/stable to reference this location directly, or is there a better way that doesn't depend on version numbers?
參考解法
方法 1:
This is a working answer for me:
/Users/Eric/.rbenv/versions/1.9.3‑p392/lib/ruby/gems/1.9.1/gems/sass‑3.2.9/bin/sass
It's not the best because I have to update the location when I upgrade SASS, but it's functional. Hope this helps someone else.
If someone knows of a symlink to the executable that is maintained through upgrades by rbenv or ruby, please share.
方法 2:
Use which sass instead of whereis. It should be in ~/.rbenv/bin location for you.
