Rbenv 没有正确重新散列和制作垫片

Question

最重要的是，rbenv 不是在制造垫片。我已经用尽了可能是什么问题的想法。经过几天的撞墙修复无果，我想是时候寻求帮助了。

我正在尝试从 RVM 切换到 rbenv，所以这显然是一个因素。任何 ideas/help 都很好。

情况如下：

[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 
[1] pry(main)> puts "I'm working now"
I'm working now

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

这是我的 gem 环境：

[09:44] ~ $ gem env

这是我的 .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:

[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"

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

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

这是在我安装 rbenv 时创建的，它与我使用 rbenv 的其他系统的设置相匹配，包括一些以前安装了 RVM 的系统。

您的双重 PATH 分配看起来像是罪魁祸首。将我系统的 PATH 与你的系统进行比较，后者由 gem env:

列出

 - /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，我的which pryreturns:

/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
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:

我会执行以下步骤：

修改 ~/.bashrc 和其他文件，删除任何引用 rbenv and/or RVM 的行。 RVM 使用所有三个初始化文件，加上 .zshrc，而 rbenv 似乎只涉及到 ~/.bash_profile.
关闭终端会话。重新打开它。
确认 PATH 没有对 RVM 和 rbenv 的所有引用。
按照 Installation 说明重新安装 rbenv。它不会覆盖当前安装，而是将其更改重新安装到 ~/.bash_profile.
再次关闭终端会话并重新打开。

rbenv 现在应该正确初始化了。
