成功安装后无法运行sass [英] can't run sass after successfully installing it

问题描述

我做了 sudo gem install sass ，它成功了。运行 sudo sass -v 可以正常工作，但以普通用户身份运行：

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

事实上，可执行文件的权限为700.我将权限更改为755，但导致：

  $ sass -v 
 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in`to_specs'：找不到'sass'（> = 0）从/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency获得的4个gem（s）（Gem :: LoadError）
中。 rb：307：在`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了所有内容，但无法找到解决方案。这是 gem env 的输出，如果我做了 sudo gem env ，那么它是相同的。

  $ gem env 
 RubyGems环境：
  -  RUBYGEMS VERSION：2.0.3 
  -  RUBY VERSION：2.0.0（安装目录：/Library/Ruby/Gems/2.0.0 
  -  RUBY EXECUTABLE：/System/Library/Frameworks/Ruby。 / usr / bin / ruby​​ 
  - 可执行目录： b  - 创业板路径：
  -  /Library/Ruby/Gems/2.0.0 
  -  /Users/ashish/.gem/ruby/2.0.0 
  -  / System / Library / Frameworks / Ruby.framework / Versions / 2.0 / usr / lib / ruby​​ / gems / 2.0.0 
  -  GEM配置：
  - ：update_sources => true 
  - ：verbose => true 
  - ：backtrace => false 
  - ：bulk_threshold => 1000 
  - 远程来源：
  -  https://rubygems.org/ 
  

我不得不使用sudo来安装。否则，我会得到：

  $ gem install sass 
错误：执行gem时（Gem :: FilePermissionError ）
您没有对/Library/Ruby/Gems/2.0.0目录的写入权限。 
  

解决方案

它适用于我：
- First我已经安装了Homewbrew：

$ p $ / usr / bin / ruby​​ -e$（curl -fsSL https：// raw .githubusercontent.com / homebrew / install / master / install）


（不要为此使用sudo步骤!!）

• 验证安装：
  
  

  brew -v




• 验证您的Ruby安装包含：

  
  
  

  ruby​​ -v




• 安装sass with

  
  
  

  gem install sass




• 验证宝石：
  
  --version

最后做：

  rvm list known已知
  

现在我有：
laomusics -mbp％ruby -v
ruby​​ 2.3.0p0（2015-12-25修订版53290）[x86_64-darwin10.0]
在OSX 1068，MBP。

希望这有助于其他人！

I did sudo gem install sass, which succeeded. Running sudo sass -v works fine, but running as a normal user gives:

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

Indeed the executable's permissions are 700. I changed the permissions to 755, but that leads to:

$ 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>'

I've google'd for everything but can't find a solution to this. Here's the output of gem env, which is identical if I do sudo gem env.

$ gem env

I had to use sudo to install. Otherwise, I get:

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

解决方案

It worked for me: - First I´ve installed Homewbrew with:

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

(DO NOT use sudo for this step!!)

• verify the install with :

  brew -v

• verify your Ruby install with :

  ruby -v

• install sass with

  gem install sass

• verify gem with:

  sass --version

and finally do:

rvm list known

Now I have: laomusics-mbp% ruby -v ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin10.0] in a OSX 1068, MBP.
