尝试安装Rails(OSX)时出现权限错误 [英] Permission Error When Trying To Install Rails (OSX)

问题描述

我是编程新手，正在尝试在终端上安装滑轨.我一直在遵循一位朋友的指示，安装了xcode命令行工具，自制软件，git，rbenv，ruby-build，ruby gems，ruby和postgres.但是每当我尝试$ gem install rails时，我都会得到以下信息:

I am new to programming and am trying to get rails installed on my terminal. I have been following instructions from a friend, installing the xcode command line tools, homebrew, git, rbenv, ruby-build, ruby gems, ruby, and postgres. But whenever, I try $gem install rails, I get the following:

Russell-Silvers-MacBook-Pro:~ Russell_Silver$ gem install rails
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_sysopen - /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/rails-4.2.0/README.md

这尤其令人沮丧，因为当我运行$ gem list时，它说我有rails 3.2.18.这很奇怪，因为当我运行$ rails v $时，它告诉我我有Rails 4.2.0.

This is especially frustrating because when I run $gem list, it says I have rails 3.2.18. Which is peculiar, because when I run $rails v$, it tells me I have Rails 4.2.0.

当我尝试使用导轨rails my new_app

Errno::EACCES: Permission denied @ rb_sysopen - /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/rails-4.2.0/README.md
An error occurred while installing rails (4.2.0), and Bundler cannot continue.
Make sure that `gem install rails -v '4.2.0'` succeeds before bundling.
         run  bundle exec spring binstub --all
/Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/shared_helpers.rb:83: warning: Insecure world writable dir /Users/Russell_Silver in PATH, mode 040707
bundler: command not found: spring

Russell-Silvers-MacBook-Pro:~ Russell_Silver$ bundle install

Could not locate Gemfile or .bundle/ directory

这真的令人沮丧，尤其是对于像我这样的编程新手来说，所以我正在寻求可能知道哪里出问题的任何人的帮助.

This is really frustrating, especially for someone new to programming such as myself, so I am seeking help from anybody who might know what is wrong.

推荐答案

您的rbenv安装未正确安装，因为它具有提升的特权，这导致您的用户帐户无权访问~/.rbenv.

Your rbenv installation was incorrectly installed as it had elevated privileges which caused your user account to not have write access to ~/.rbenv.

发出以下命令以获取目录的所有权:

Issue the following command in order to take of ownership of the directory:

 sudo chown -R Russell_Silver ~/.rbenv

请注意，某些用户可能具有不同的rbenv目录，例如/usr/local/var/rbenv.这将代替上述命令中的~/.rbenv.

Note that some users may have a different rbenv directory, e.g. /usr/local/var/rbenv. This would take the place of ~/.rbenv in the above command.
