成功安装后无法运行sass

Question

我做了sudo gem install sass,成功了.运行sudo sass -v正常,但作为普通用户运行给出:

$ sass -v
-bash: /usr/bin/sass: Permission denied

实际上,可执行文件的权限是700.我将权限更改为755,但这导致:

$ sass -v
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in `to_specs': Could not find 'sass' (>= 0) among 4 total gem(s) (Gem::LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:in `to_spec'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in `gem'
    from /usr/bin/sass:22:in `<main>'

我已经google了所有的东西,但无法找到解决方案.这是输出gem env,如果我这样做是相同的sudo gem env.

$ gem env
RubyGems Environment:
  - RUBYGEMS VERSION: 2.0.3
  - RUBY VERSION: 2.0.0 (2013-06-27 patchlevel 247) [universal.x86_64-darwin13]
  - INSTALLATION DIRECTORY: /Library/Ruby/Gems/2.0.0

     - :verbose => true
     - :backtrace => false

我不得不使用sudo进行安装.否则,我得到:

$ gem install sass
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

它对我有用: - 首先我安装了Homewbrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

(不要在这一步使用sudo !!)

• 验证安装:

  brew -v

• 验证您的Ruby安装:

  红宝石-v

• 用.安装sass

  宝石安装sass

• 验证宝石:

  sass --version

最后做:

rvm list known

现在我在OSX 1068,MBP中有:laomusics-mbp%ruby -v ruby​​ 2.3.0p0(2015-12-25 revision 53290)[x86_64-darwin10.0].

希望这有助于他人!
