Rbenv没有正确地使用垫片和垫片

Question

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

我试图从RVM切换到rbenv，所以这显然可能是一个因素在这里。任何想法/帮助将会很棒。

这里发生了什么：

[09:38] ~ $ gem install pry 
Fetching: pry-0.10.2.gem (100%) 
Successfully installed pry-0.10.2 
1 gem installed 

[09:39] ~ $ rbenv rehash 

[09:40] ~ $ pry 
bash: pry: command not found 

[09:40] ~ $ rbenv which pry 
rbenv: pry: command not found 

[09:40] ~ $ which pry 
which: no pry in (/home/caveman/.rbenv/plugins/ruby-build/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/home/caveman/.rbenv/plugins/ruby-build/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl) 

[09:41] ~ $ ~/.gem/ruby/2.2.0/bin/pry

[09:43] ~ $ gem list | grep pry 
pry (0.10.2)

这里是我的.bashrc文件：

[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" 

这里是.bash_profile文件：

[09:52] ~ $ cat .bash_profile 

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

source ~/.profile 

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

我怀疑你的.bashrc是问题所在。它不应该包含：

# 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" 

我的〜/ .bashrc，〜/ .profile文件和〜/ .bash_profile中的文件，只有最后一次有配置rbenv：

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

所创建的时候我安装了rbenv，它与我使用rbenv的其他系统的设置相匹配，其中包括以前安装了RVM的一些系统。

您的双路径任务看起来像罪魁祸首。比较PATH我的系统，以你的，这是由gem env上市：

- /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 

同样，我which pry回报：

/Users/ttm/.rbenv/shims/pry 

使用rbenv的env plugin显示：

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

RBENV_SHELL=bash 
RBENV_DIR=/Users/ttm 
RUBYLIB=/Users/ttm/.rbenv/rbenv.d/exec/gem-rehash: 

我会请执行以下步骤：

1. 修改〜/ .bashrc和其他文件，删除引用rbenv和/或RVM的所有行。 RVM使用所有三个init文件，加上.zshrc，而rbenv似乎只接触〜/ .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Installation说明重新安装rbenv。它不会覆盖当前的安装，而是会重新安装对〜/ .bash_profile的更改。
5. 再次关闭终端会话并重新打开它。

rbenv现在应该正确初始化。
