问题描述

底线是，rbenv没有做垫片。我已经穷尽了可能是问题的想法。几天后，我的头撞到了墙上，但无济于事，我认为该是寻求帮助的时候了。



我试图从RVM到rbenv，所以这显然可能是一个因素。任何想法/帮助都会很棒。



以下是发生的情况：

这是我的gem环境：

＃如果没有运行交互式地，不要做任何事

 export PATH = $ HOME / .rbenv / bin：$ PATH
 eval$（rbenv init  - ）
 export PATH =$ HOME / .rbenv / plugins / ruby​​-build / bin：$ PATH

这里是.bash_profile： 

  [09:52]〜$ cat .bash_profile 
 
 [[-f〜/ .bashrc]]&& 。 〜/ .bashrc 
 $ b $ source〜/ .profile 
 
 export PATH =$ HOME / .rbenv / bin：$ PATH
 eval$（rbenv init - ）


解决方案

我怀疑你的.bashrc是个问题。它不应该包含： 

 ＃如果我没有设置它，那么gem会回到不存在的RVM目录。 
 export GEM_HOME = $（ruby -e'print Gem.user_dir'）
 export GEM_PATH = $（ruby -e'print Gem.user_dir'）
 
 export PATH = $ HOME / .rbenv / bin：$ PATH
 eval$（rbenv init  - ）
 export PATH =$ HOME / .rbenv / plugins / ruby​​-build / bin：$ PATH

在我的〜/ .bashrc，〜/ .profile和〜/ .bash_profile文件中，只有最后一个rbenv的配置：

 ＃echo使用rbenv ... 
 export PATH =$ HOME / .rbenv / bin ：$ PATH
 eval$（rbenv init  - ）

我安装了rbenv，它与我使用rbenv的其他系统的设置相匹配，包括以前安装了RVM的一些系统。



您的双路径分配看起来像是罪魁祸首。将我的系统的PATH与 gem env 列出的你的进行比较： 

   -  /Users/ttm/.rbenv/versions/2.2.3/bin 
  -  /Users/ttm/.rbenv/libexec 
  -  /Users/ttm/.rbenv/plugins/ruby- build / bin 
  -  /Users/ttm/.rbenv/plugins/rbenv-whatis/bin 
  -  /Users/ttm/.rbenv/plugins/rbenv-vars/bin 
  -  / Users /ttm/.rbenv/plugins/rbenv-use/bin 
  -  /Users/ttm/.rbenv/plugins/rbenv-update/bin 
  -  /Users/ttm/.rbenv/plugins/rbenv- update-rubies / bin 
  -  /Users/ttm/.rbenv/plugins/rbenv-gemset/bin

  - /Users/ttm/.rbenv/plugins/rbenv-each/bin 
  -  /Users/ttm/.rbenv/shims 
  -  /Users/ttm/.rbenv/bin

同样，我的 pry 返回：

  /Users/ttm/.rbenv/shims/pry

使用rbenv的 env 插件显示：

  RBENV_VERSION = 2.2.3 
 RBENV_GEMSET_ALREADY =是
 RBENV_ROOT = / Users / ttm / .rbenv 
 RBENV_HOOK_PATH =： /Users/ttm/.rbenv/rbenv.d:/usr/local/etc/rbenv.d:/etc/rbenv.d:/usr/lib/rbenv/hooks:/Users/ttm/.rbenv/plugins/rbenv -default-宝石的/ etc / rbenv.d：/Users/ttm/.rbenv/plugins/rbenv-gemset/etc/rbenv.d：/Users/ttm/.rbenv/plugins/rbenv-readline/etc/rbenv.d ：/Users/ttm/.rbenv/plugins/rbenv-vars/etc/rbenv.d 
 PATH = / Users / ttm / .rbenv / versions / 2.2.3 / bin：/Users/ttm/.rbenv/的libexec：/Users/ttm/.rbenv/plugins/ruby-build/bin：/Users/ttm/.rbenv/plugins/rbenv-whatis/bin：/Users/ttm/.rbenv/plugins/rbenv-vars/bin： /Users/ttm/.rbenv/plugins/rbenv-use/bin:/Users/ttm/.rbenv/plugins/rbenv-update/bin:/Users/ttm/.rbenv/plugins/rbenv-update-rubies/bin： /Users/ttm/.rbenv/plugins/rbenv-gemset/bin:/Users/ttm/.rbenv/plugins/rbenv-env/bin:/Users/ttm/.rbenv/plugins/rbenv-each/bin:/Users /ttm/.rbenv/shims:/Users/ttm/.rbenv/bin:/Users/ttm/.pyenv/shims:/Users/ttm/.pyenv/bin:/Users/ttm/perl5/perlbrew/bin:/我们ERS / TTM /的perl5 / perlbrew /皮尔斯/ Perl的5.18.1 / bin中：/用户/ TTM / bin中：/usr/local/mysql-5.6.16-osx10.7-x86_64/bin：/用户/ TTM / libsmi /bin:/usr/local/git/bin:/usr/local/bin:/Library/PostgreSQL/9.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin ：/ opt / X11 / bin：/ usr / local / git / bin 
 RBENV_SHELL = bash 
 RBENV_DIR = / Users / ttm 
 RUBYLIB = / Users / ttm / .rbenv / rbenv.d / exec / gem-rehash：

我会执行以下步骤：


  1. 修改〜/ .bashrc和其他文件，删除引用rbenv和/或RVM的所有行。 RVM使用全部三个init文件，加上.zshrc，而rbenv只能触及〜/ .bash_profile。

  2. 关闭终端会话。重新打开它。

  3. 确认PATH没有对RVM和rbenv的所有引用。

  4. 按照安装说明。它不会覆盖当前安装，而是会重新安装对〜/ .bash_profile的更改。 再次关闭终端会话并重新打开它。

rbenv现在应该正确初始化。


The bottom line is, rbenv isn't making shims. I've exhausted ideas of what could be the problem. After a few days of banging my head against a wall to fix but no avail, I think it's time to ask for help.

I'm attempting to make the switch from RVM to rbenv, so that could obviously be a factor here. Any ideas/help would be great.

Here's what happens:

Here's my gem environment:

Here is my .bashrc file: 

[09:46] ~ $ cat .bashrc
# If not running interactively, don't do anything
[[ $- != *i* ]] && return

# If I don't set this, gem reverts back to nonexistent RVM directory.
export GEM_HOME=$(ruby -e 'print Gem.user_dir')
export GEM_PATH=$(ruby -e 'print Gem.user_dir')

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

And here is .bash_profile:

[09:52] ~ $ cat .bash_profile 

[[ -f ~/.bashrc ]] && . ~/.bashrc

source ~/.profile

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

解决方案

I suspect your .bashrc is the problem. It shouldn't contain:

# If I don't set this, gem reverts back to nonexistent RVM directory.
export GEM_HOME=$(ruby -e 'print Gem.user_dir')
export GEM_PATH=$(ruby -e 'print Gem.user_dir')

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

Of my ~/.bashrc, ~/.profile and ~/.bash_profile files, only the last has configuration for rbenv:

# echo Using rbenv...
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

That was created when I installed rbenv, which matches the settings for my other systems where I use rbenv, including some that previously had RVM installed.

Your double PATH assignments look like the culprit. Compare the PATH for my system to yours, which is listed by gem env:

 - /Users/ttm/.rbenv/versions/2.2.3/bin
 - /Users/ttm/.rbenv/libexec
 - /Users/ttm/.rbenv/plugins/ruby-build/bin
 - /Users/ttm/.rbenv/plugins/rbenv-whatis/bin
 - /Users/ttm/.rbenv/plugins/rbenv-vars/bin
 - /Users/ttm/.rbenv/plugins/rbenv-use/bin
 - /Users/ttm/.rbenv/plugins/rbenv-update/bin
 - /Users/ttm/.rbenv/plugins/rbenv-update-rubies/bin
 - /Users/ttm/.rbenv/plugins/rbenv-gemset/bin
 - /Users/ttm/.rbenv/plugins/rbenv-env/bin
 - /Users/ttm/.rbenv/plugins/rbenv-each/bin
 - /Users/ttm/.rbenv/shims
 - /Users/ttm/.rbenv/bin

Similarly, my which pry returns:

/Users/ttm/.rbenv/shims/pry

Using rbenv's env plugin shows:

RBENV_VERSION=2.2.3
RBENV_GEMSET_ALREADY=yes
RBENV_ROOT=/Users/ttm/.rbenv
RBENV_HOOK_PATH=:/Users/ttm/.rbenv/rbenv.d:/usr/local/etc/rbenv.d:/etc/rbenv.d:/usr/lib/rbenv/hooks:/Users/ttm/.rbenv/plugins/rbenv-default-gems/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-gemset/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-readline/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-vars/etc/rbenv.d
PATH=/Users/ttm/.rbenv/versions/2.2.3/bin:/Users/ttm/.rbenv/libexec:/Users/ttm/.rbenv/plugins/ruby-build/bin:/Users/ttm/.rbenv/plugins/rbenv-whatis/bin:/Users/ttm/.rbenv/plugins/rbenv-vars/bin:/Users/ttm/.rbenv/plugins/rbenv-use/bin:/Users/ttm/.rbenv/plugins/rbenv-update/bin:/Users/ttm/.rbenv/plugins/rbenv-update-rubies/bin:/Users/ttm/.rbenv/plugins/rbenv-gemset/bin:/Users/ttm/.rbenv/plugins/rbenv-env/bin:/Users/ttm/.rbenv/plugins/rbenv-each/bin:/Users/ttm/.rbenv/shims:/Users/ttm/.rbenv/bin:/Users/ttm/.pyenv/shims:/Users/ttm/.pyenv/bin:/Users/ttm/perl5/perlbrew/bin:/Users/ttm/perl5/perlbrew/perls/perl-5.18.1/bin:/Users/ttm/bin:/usr/local/mysql-5.6.16-osx10.7-x86_64/bin:/Users/ttm/libsmi/bin:/usr/local/git/bin:/usr/local/bin:/Library/PostgreSQL/9.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin
RBENV_SHELL=bash
RBENV_DIR=/Users/ttm
RUBYLIB=/Users/ttm/.rbenv/rbenv.d/exec/gem-rehash:

I'd do these steps:

  1. Modify ~/.bashrc, and the others, removing any lines referring to rbenv and/or RVM. RVM uses all three init files, plus .zshrc, whereas rbenv only seems to touch ~/.bash_profile.
  2. Close the terminal session. Reopen it.
  3. Confirm the PATH is free from all references to RVM and rbenv.
  4. Reinstall rbenv following the Installation instructions. It won't override the current installation, but instead will reinstall its changes to ~/.bash_profile.
  5. Close the terminal session again and reopen it.

rbenv should now be initialized correctly.
