I'm working with ubuntu 12.04.
我正在使用 ubuntu 12.04。
This is my ~/.profilefile:
这是我的~/.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 -)"

rbenv needs these at the end of your ~/.bash_profile:
rbenv 在你的~/.bash_profile末尾需要这些：
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
Use grep rbenv ~/.bash_profileto see if they're there.
使用grep rbenv ~/.bash_profile，看他们是否在那里。
If not, run:
如果没有，请运行：
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
exec $SHELL -l
and you should be up and running.
你应该启动并运行。
See steps 2 and 3 in the docsfor more information.

Run env | grep PATHand make sure that you have $HOME/.rbenv/binin your PATH.
运行env | grep PATH并确保$HOME/.rbenv/bin您的路径中有。
If it is not, add this to ~/.bash_profile.
如果不是，请将其添加到 ~/.bash_profile。
export PATH="$HOME/.rbenv/bin:$PATH"
