Issue installing RVM for RoR in Ubuntu

Question

I'm trying to get Ruby on Rails setup on my new eeeubuntu install and I think I'm having some issues installing RVM properly.

I installed GIT, and that went well. I installed RVM and in the install it told me to add

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

To the end of .bashrc Which I did.

It then said if I have a return in .bashrc it would cause errors. So it said move everything below

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

To .bash_profile Which I did. When I try and run "rvm install 1.9.1" I get this

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

So what have I done wrong?

Here are the contents of my .bashrc and .bash_profile

.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

# 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
fi

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

# If this is an xterm set the title to user@host:dir

esac

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then

    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'

fi

#alias ll='ls -l'
#alias la='ls -A'
#alias l='ls -CF'

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

# 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 [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion
fi

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

Answer 1

You need not to move but to remove the return.

You also need to add some code to .bashrc. You added it to .bash_profile but not to .bashrc. The line you need to append is

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

Please read the instructions from the installer carefully again! I am not sure if there were other things you needed to add.

Answer 2

I added to .bashrc export PATH=~/.rvm/bin:$PATH and it worked for me

문서가 끔찍하게 설명하는 것처럼 보이지만 클래스 뒤에있는 코드를 보지 않고도 내 추측은 구현이 작업 / 스레드를 생성 할 수 있도록 실행 프로그램 인스턴스를 메서드로 전달할 것으로 예상됩니다. 연결 상태.

연결 읽기가 차단되므로 다른 종류의 시간 제한 로직을 구현하기 위해 연결 상태를 확인할 수있는 읽기가있는 다른 스레드가 필요합니다.

jdbc 드라이버 대신에 Logic을 구현하는 JDBC 드라이버 대신에 스레드가 처리 할 수있는 /시기의 경우, API는 사용자가 사용될 이벤트에서 전달할 클라이언트로 원합니다. 시간 초과를 확인하십시오. 이 방법으로 클라이언트가 검사가 실행되는 빈도와 같은 것을 제어 할 수 있으므로 컨테이너에서 더 많은 스레드를 원하는 것보다 더 많은 스레드를 산출하지 못하게합니다.

AS Executor 인스턴스가없는 경우 기본값을 만들 수 있습니다.

conn.setNetworkTimeout(Executors.newFixedThreadPool(numThreads), yourTimeout);
