如何使用rbenv在没有sudo的情况下全局安装gem？ [英] How to install a gem globally without sudo using rbenv?

问题描述

我正在使用 rbenv ，并试图安装 sass ，但没有成功。

因此，我通过自制软件安装 rbenv ，然后是Ruby 2.2（ rbenv install 2.2 ），最后是 gem install sass ，但我无法使<$我的 $ PATH 。

可用的c $ c> sass 我使用我的系统（Yosemite）默认的Ruby 2安装了sa sudo gem install sass 。这将所有内容放在 /Library/Ruby/Gems/2.0.0中。
$ b

理想情况下，使用 rbenv ，并且事情能够工作，但不是最理想的方式。我应该能够安装任何Ruby版本，并且在该版本的目录中安装gems，然后将它们symlink到 / usrl / local / bin 。

任何可能出错的帮助都将非常值得赞赏。

解决方案

基本上，问题我没有将 rbenv / bin / rbenv 添加到 $ PATH 。

  export PATH =$ HOME / .rbenv / bin：$ PATH
  

更好的是，将它添加到 .bashrc 或 .bash_profile 中，使用<$ c开始每个会话

$ p
$ b

然后，请确保：

<$ p $ p> eval$（rbenv init - ）


shims和autocompletion。

fishshell

对于那些使用鱼的人来说，你可以像这样完成： p>

  if status --is-interactive 
。 （rbenv init  -  | psub）
 end 
  

现在，如果您不喜欢修改 $ PATH ，并拥有 / usr / local / bin 的所有权，一个更好的解决方案是使用〜/ .rbenv / bin / rbenv 。

  ln -s〜/。 rbenv / bin / rbenv / usr / local / bin 
  

ruby​​-build

作为最终警告，请确保安装 ruby​​-建立 （a rbenv 插件将安装命令添加到 rbenv 并且能够轻松安装Ruby版本。）

如果您使用 homebrew 这很容易：

  brew install ruby​​-build 
  

I am using rbenv and I am trying to install sass without success.

So, I installed rbenv via Homebrew, then Ruby 2.2 (rbenv install 2.2) and finally gem install sass, but I was unable to make sass available on my $PATH.

Short on time, I sudo gem install sass using my system's (Yosemite) default Ruby 2. This put everything in /Library/Ruby/Gems/2.0.0 and things do work, but not in the most desireable way.

Ideally, using rbenv I should be able to install any Ruby version and have gems installed inside that version's directory and later symlinked to /usrl/local/bin.

Any help as to what could have gone wrong would be very much appreciated.

解决方案

Basically, the problem was I did not add rbenv/bin/rbenv to $PATH.

export PATH="$HOME/.rbenv/bin:$PATH"

Better yet, add this to your .bashrc or .bash_profile to start every session with rbenv.

After that, make sure to:

eval "$(rbenv init -)"

In order to enable shims and autocompletion.

fishshell

For those using fish, you can accomplish the same like this:

if status --is-interactive
  . (rbenv init - | psub)
end

Now, if you don't like modifying $PATH directly and have ownership over /usr/local/bin, a more nifty solution is to symlink with ~/.rbenv/bin/rbenv.

 ln -s ~/.rbenv/bin/rbenv /usr/local/bin

ruby-build

As a final warning, make sure to install ruby-build (a rbenv plugin to add the install command to rbenv and be able to easily install Ruby versions.)

If you are using homebrew it's easy as pie:

brew install ruby-build
