■[Cygwin][Ruby][RVM]RVMをCygwin環境で使ってみる

依存パッケージ

ruby
git
curl
ncurses
gcc (3.x or 4.x)
make

gem install rvmしたあとの初期設定

普段はgemのインストール結果に表示されるコマンドコピペで行けるんだけど、できない子のCygwinではここを見ろのURL

https://rvm.beginrescueend.com/rvm/install/

を見て、下記のコマンドを打ってあげた。

$ bash < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

shingo,

If you have any questions, issues and/or ideas for improvement please
fork the project and issue a pull request.

If you wish to disable the project .rvmrc file functionality, set
rvm_project_rvmrc=0 in either /etc/rvmrc or ~/.rvmrc.

NOTE: To Multi-User installers, please do NOT forget to add your users to the 'rvm'.
The installer no longer auto-adds root or users to the rvm group. Admins must do this.
Also, please note that group memberships are ONLY evaluated at login time.
This means that users must log out then back in before group membership takes effect!

Thank you for using RVM!

I sincerely hope that RVM helps to make your life easier and more enjoyable!!!

~Wayne

SYSTEM NOTES:

If you do not wish to enable reading of per-project .rvmrc files, simply set:
export rvm_project_rvmrc=0
within either your /etc/rvmrc or $HOME/.rvmrc file, then log out and back in.

You _must_ read 'rvm requirements' for additional OS specific requirements for
various rubies, and native-extension gems. Expect failures until those are met!

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

If you wish to use RVM in an interactive fashion in your shells then
Place the following 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/shingo/.rvm/scripts/rvm" ]] && source "/home/shingo/.rvm/scripts/rvm" # This loads RVM into a shell session.

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

If you are choosing to source RVM into your environment to switch current
shell environments, be sure to close this shell and open a new one so that
the RVM functions load.

Installation of RVM to /home/shingo/.rvm/ is complete.

ちなみにncursesを忘れたら

More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

■[Ruby][Rails3]Rails3に移行するための最初の一歩

shingo@ubuntu:~/Aptana RadRails Workspace/twitter$ ./search6.rb 
DEPRECATION WARNING: require "activerecord" is deprecated and will be removed in Rails 3. Use require "active_record" instead. (called from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.14/lib/activerecord.rb:2)

えーと、requireする名前が変わってるのを完全に忘れてた。orz

WEB+DB PRESSのバックナンバー読みながらやらないと、しょーもない間違いやらかすなー。

Rails2の最新とRails3の最新を両方入れて、ようやく原因が判明した俺ってバカ？？

■[Ubuntu][Rails3][Ruby]UbuntuでRails3のexecjsが例外を投げたら

どんなエラー？

こんな具合に例外を投げます。

$ ./script/rails server

$

どう対処するの？

エラーメッセージにある https://github.com/sstephenson/execjs を見れば、8つある"ExecJS supports these runtimes"のどれかを入れれば良いらしい。最初、therubyracerを入れたがダメだった。

それで、Node.jsを入れてあげる。

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
$ sudo apt-get install nodejs

これで平和に動きます。
