我正在使用Ubuntu 12.04。

這是我~/.profile文件：

# ~/.profile: executed by the command interpreter for login shells. 
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login 
# exists. 
# see /usr/share/doc/bash/examples/startup-files for examples. 
# the files are located in the bash-doc package. 

# the default umask is set in /etc/profile; for setting the umask 
# for ssh logins, install and configure the libpam-umask package. 
#umask 022 

# if running bash 
if [ -n "$BASH_VERSION" ]; then 
    # include .bashrc if it exists 
    if [ -f "$HOME/.bashrc" ]; then 
     . "$HOME/.bashrc" 
    fi 
fi 

# set PATH so it includes user's private bin if it exists 
if [ -d "$HOME/bin" ] ; then 
    PATH="$HOME/bin:$PATH" 
fi 
export PATH="$HOME/.rbenv/bin:$PATH" 
eval "$(rbenv init -)" 
eval "$(rbenv init -)" 
eval "$(rbenv init -)" 

我已經安裝了紅寶石rbenv最後一個版本，當我嘗試ruby -v我得到-bash: ruby: command not found

Answer 1

rbenv在您〜/ .bash_profile中到底需要這些：

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

使用grep rbenv ~/.bash_profile，看看他們在那裏。

如果沒有，運行：

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile 
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile 
exec $SHELL -l 

，你應該是啓動和運行。

Answer 2

運行env | grep PATH，並確保你在你的PATH有$HOME/.rbenv/bin 。

如果不是，請將其添加到〜/ .bash_profile。

export PATH="$HOME/.rbenv/bin:$PATH"
