在Ubuntu中为RoR安装RVM的问题

Question

我正在尝试在我的新eeeubuntu安装上安装Ruby on Rails,我认为我在安装RVM时遇到了一些问题.

我安装了GIT,这很顺利.我安装了RVM并在安装中告诉我添加

if [[ -s /home/derek/.rvm/scripts/rvm ]] ; then source /home/derek/.rvm/scripts/rvm ; fi

到.bashrc结束我做了什么.

然后它说如果我在.bashrc中有一个返回它会导致错误.所以它说下面的一切

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

to .bash_profile我做了什么.当我尝试运行"rvm install 1.9.1"时,我得到了这个

No command 'rvm' found, but there are 20 similar ones
rvm: command not found

那我做错了什么？

这是我的.bashrc和.bash_profile的内容

的.bashrc

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

.bash_profile中

# don't put duplicate lines in the history. See bash(1) for more options
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
# ... or force ignoredups and ignorespace
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color) color_prompt=yes;;
esac

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
 # We have color support; assume it's compliant with Ecma-48
 # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
 # a case would tend to support setf rather than setaf.)
color_prompt=yes
    else
 color_prompt=

fi

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;    34m\]\w\[\033[00m\]\$ '

# Alias definitions.
# You may want to put all your additions into a separate file like

# See /usr/share/doc/bash-doc/examples in the bash-doc package.

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).

if [[ -s /home/derek/.rvm/scripts/rvm ]] ; then source /home/derek/.rvm/scripts/rvm ; fi

Answer 1

你不需要移动,但删除return.

您还需要添加一些代码.bashrc.你添加了.bash_profile但不是.bashrc.您需要追加的行是

if [[ -s /home/derek/.rvm/scripts/rvm ]] ; then source /home/derek/.rvm/scripts/rvm ; fi

请再次仔细阅读安装人员的说明!我不确定是否还有其他需要添加的东西.

我添加到了.bashrc export PATH=~/.rvm/bin:$PATH,它对我有用
