Ruby on Rails Tutorial: Learn Rails by Example 这个书很不错诶 不过 有没有中文的？

@n2n3 macruby 和 ruby 不太一样吧

@huacnlee 不太懂怎么加[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"


T T

@roamlog ls cd 什么的基本的知道 其他的就不懂了

@huacnlee 能详细点 说明吗？

@ashchan .bash_login 或.bash_profile，要怎么加入？

怎么看 shell 原来用的什么

@lainuo source 是什么？ 命令吗？还是？

怎么打开shell 看呢？

ez6490,

Thank you very much for using RVM! I sincerely hope that RVM helps to
make your work both easier and more enjoyable.

If you have any questions, issues and/or ideas for improvement please
join#rvm on irc.freenode.net and let me know, note you must register
(http://bit.ly/5mGjlm) and identify (/msg nickserv <nick> <pass>) to
talk, this prevents spambots from ruining our day.

My irc nickname is 'wayneeseguin' and I hang out in #rvm typically

~09:00-17:00EDT and again from ~21:00EDT-~23:00EDT

If I do not respond right away, please hang around after asking your
question, I will respond as soon as I am back. It is best to talk in
#rvm itself as then other users can help out should I be offline.

Be sure to get head often as rvm development happens fast,
you can do this by running 'rvm get head' followed by 'rvm reload'
or opening a new shell

w⦿‿⦿t

~ Wayne


$ rvm notes
-bash: rvm: command not found

我刚刚开始接触编程 比较小白 所以希望大家多帮帮忙 在这里先多谢了 。

You must now complete the install by loading RVM in new shells.

1) Place the folowing line at the end of your shell's loading files
(.bashrc or .bash_profile for bash and .zshrc for zsh),
after all PATH/variable settings:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.

You only need to add this line the first time you install rvm.

2) Ensure that there is no 'return' from inside the ~/.bashrc file,
otherwise rvm may be prevented from working properly.


This means that if you see something like:

'[ -z "$PS1" ] && return'

then you change this line to:

if [[ -n "$PS1" ]] ; then

# ... original content that was below the '&& return' line ...

fi # <= be sure to close the if at the end of the .bashrc.

# This is a good place to source rvm v v v
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.

EOF - This marks the end of the .bashrc file

Be absolutely *sure* to REMOVE the '&& return'.

If you wish to DRY up your config you can 'source ~/.bashrc' at the bottom of your .bash_profile.

Placing all non-interactive (non login) items in the .bashrc,
including the 'source' line above and any environment settings.

3) CLOSE THIS SHELL and open a new one in order to use rvm.


Installation of RVM to /Users/ez6490/.rvm/ is complete.

后来我尝试了一下rvm 但是安装完 我就崩溃了 代码如下

Notes for Darwin ( Mac OS X )
For Snow Leopard be sure to have Xcode Tools Version 3.2.1 (1613) or later
You should download the latest Xcode tools from developer.apple.com.
(This is since the dvd install for Snow Leopard contained bugs).

If you intend on installing MacRuby you must install LLVM first.
If you intend on installing JRuby you must install the JDK.
If you intend on installing IronRuby you must install Mono (version 2.6 or greater is recommended).

To seamlessly abandon the Apple-installed system ruby (ruby 1.8.7 patchlevel 174 for Snow Leopard):

rvm install 1.8.7 # installs patch 302: closest supported version
rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system # migrate your gems
rvm --default 1.8.7

Generally there are no consequences of this for you, however if you build
your own software and it requires this formula, you may want to run this
command to link it into the Homebrew prefix:
$ brew link readline

Consider using RVM or Cinderella to manage Ruby environments:

* Cinderella: http://www.atmos.org/cinderella/

NOTE: By default, gem installed binaries will be placed into:
/usr/local/Cellar/ruby/1.9.2-p136/bin

You may want to add this to your PATH.
