@H_404_4@我正在使用ubuntu 12.04.

@H_404_4@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 -)"
eval "$(rbenv init -)"
eval "$(rbenv init -)"

@H_404_4@我用rbenv安装了ruby最后一个版本,当我尝试ruby -v时,我得到-bash：ruby：command not found

解决方法

rbenv在〜/ .bash_profile的末尾需要这些：

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

@H_404_4@使用grep rbenv~ / .bash_profile查看它们是否在那里.

@H_404_4@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

@H_404_4@你应该开始运作.

@H_404_4@有关详细信息,请参阅the docs中的步骤2和3.
