我正在使用ubuntu 12.04.
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 "$(rbenv init -)"
我用rbenv安装了ruby最后一个版本,当我尝试ruby -v时,我得到-bash：ruby：command not found
解决方法
rbenv在〜/ .bash_profile的末尾需要这些：
export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)"
使用grep rbenv~ / .bash_profile查看它们是否在那里.
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
你应该开始运作.
