设置环境，OSX rbenv和捆绑包之战 [英] Setting up env, OSX rbenv and bundle battle

问题描述

所以我刚从ubuntu切换到Mac，设置环境并不像承诺的那样容易.

这是我遵循的过程.

1. 安装了xcode-然后进入偏好并下载了command line tools

2. 然后通过运行gcc --version

   验证是否安装了正确的版本.

   i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

   warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
   

3. 然后安装自制软件$ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

4. 跑了brew doctor，这就是我得到的

   Your system is ready to brew.

5.已安装git brew update + brew install git

6.通过ssh将我的电脑链接到我的git帐户

7.已安装Rbenv

$ brew update
$ brew install rbenv
$ brew install ruby-build

将eval "$(rbenv init -)"添加到了我的.bash_profile文件中

1. 运行rbenv install -list以查看我可以安装然后运行的所有版本

   $ rbenv install 1.9.3-p327
   $ rbenv global 1.9.3-p327
   

2. (我应该重新整理rbenv但我忘了)然后我运行了gem install bundler

3. 然后进入我的一个仓库中并运行bundle install，它因错误而崩溃

   Gem::InstallError: better_errors requires Ruby version >= 1.9.2.
   An error occurred while installing better_errors (0.7.0), and Bundler cannot continue.
   Make sure that `gem install better_errors -v '0.7.0'` succeeds before bundling.
   

运行ruby -v并发现它在1.8.7球"上-我惊呼

1. 为了解决这个问题，我做了以下rbenv rehash

2. ruby -v然后得到ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.3.0]然后高个子自己

3. 然后尝试运行捆绑软件，出现相同的错误?

   $ which bundle
   /usr/bin/bundle
   
   $ which gem
   /Users/fortknokx/.rbenv/shims/gem
   

所以这就是我现在感到困惑的地方.正如我所说的，这是我使用Mac的第三天，我对了解$ PATH感到很陌生，我确信自己在某个地方犯了规.我愿意接受的任何建议.

ps，这就是我的.bash_profile中的内容

export PATH="/usr/local/bin:/usr/local/bin/sublime:~/bin:$PATH"
eval "$(rbenv init -)"

解决方案

问题似乎是您使用的是安装了系统ruby的捆绑程序，而不是使用rbenv ruby​​安装的.

运行ruby --version以确保您的rbenv红宝石处于活动状态，然后运行gem install bundler，然后运行rbenv rehash，然后尝试重新安装gems，看看是否可行.

So i have just swapped over to mac from ubuntu and setting up the env has not been as easy as promised.

this is the process i followed.

1. installed xcode - then went into the prefrences and downloaded the command line tools

2. then verified that the right version was installed, by running gcc --version

   i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

   warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
   

3. then installed homebrew $ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

4. ran brew doctor and this is what i get

   Your system is ready to brew.

5.installed git brew update + brew install git

6.linked my pc to my git account via ssh

7.installed Rbenv

$ brew update
$ brew install rbenv
$ brew install ruby-build

added eval "$(rbenv init -)" to my .bash_profile file

1. ran rbenv install -list to see all the versions i could install and then ran

   $ rbenv install 1.9.3-p327
   $ rbenv global 1.9.3-p327
   

2. (i should have rehashed rbenv but i forgot) i then ran gem install bundler

3. then went into one of my repo's and ran bundle install which blew up with errors

   Gem::InstallError: better_errors requires Ruby version >= 1.9.2.
   An error occurred while installing better_errors (0.7.0), and Bundler cannot continue.
   Make sure that `gem install better_errors -v '0.7.0'` succeeds before bundling.
   

ran ruby -v and saw that it was on 1.8.7 "balls" - i exclaimed

1. to remedy this i did the following rbenv rehash

2. ruby -v and got ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.3.0] then high fived myself

3. then tried to run bundle and the same error comes up ??

   $ which bundle
   /usr/bin/bundle
   
   $ which gem
   /Users/fortknokx/.rbenv/shims/gem
   

so this is now where i stand confused as heck. as i said this is my third day using mac and i am pretty new to understanding the $PATH i am sure that i made a foul up somewhere. any advice i am open to.

ps this is what i have in my .bash_profile

export PATH="/usr/local/bin:/usr/local/bin/sublime:~/bin:$PATH"
eval "$(rbenv init -)"

解决方案

The problem seems to be that you're using a system ruby installed bundler, and not one installed with your rbenv ruby.

Run ruby --version to make sure your rbenv ruby is active, then run gem install bundler followed by rbenv rehash and then try reinstalling your gems and see if that works.
