記得兩年前使用ror做網(wǎng)站，自動(dòng)生成功能記憶猶新，只是當(dāng)時(shí)網(wǎng)絡(luò)知識實(shí)在缺乏，體會(huì)不到其中的樂趣。現(xiàn)在了解的很多了，書也有兩本，一直想重新體驗(yàn)最新版做個(gè)網(wǎng)站。安裝這個(gè)過程實(shí)在有點(diǎn)坑爹，查找網(wǎng)上若干ror的書包括2012年版的書，按照上面的步驟都沒法安裝完成，搞得我一會(huì)在linux下試驗(yàn)，一會(huì)在windows下試驗(yàn)，都沒成功，只好放下。時(shí)間花不少，很不爽的體驗(yàn)。
好在，過了一段時(shí)間，忽然想看看ruby的那兩本書，然后就愛上這個(gè)語言了。于是做一些想做的試驗(yàn)，一些試驗(yàn)需要做些配置，對安裝目錄也就了解了。下載一些插件居然自己跑到了ruby的下載頁。看到上面居然一個(gè)版本有3樣要下的，幫助文件和安裝文件不就夠了嗎。還要一個(gè)mingw做工具么？這個(gè)不是有自己的官網(wǎng)下載么。也沒管。想起ruby目錄下include中有i386-mingw32，才聯(lián)系起來。應(yīng)該是以mingw做make工具的。rails應(yīng)該需要make，因?yàn)槊看伟惭b都拋出make出錯(cuò)信息。雖然有mingw官網(wǎng)，但這里應(yīng)該是做成自己的插件。于是到下載頁http://rubyforge.org/frs/?group_id=167下載相應(yīng)版本的mingw32工具解壓覆蓋到安裝目錄中，要是怕出問題先對目錄做備份
另外下載不了的都cross wall下載
C:\Documents and Settings\Administrator>gem install rails
ERROR: Error installing rails:
The 'json' native gem requires installed build tools.
Please update your PATH to include build tools or download the DevKit

還有錯(cuò)，但明顯不是曾經(jīng)報(bào)的make錯(cuò)誤了。
按照網(wǎng)址下載和遵從上面的方法安裝即可（下面的命令即是按照安裝方法安裝的）
其中config.yml文件僅僅描述ruby所在路徑，修改成你的ruby路徑即可

Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!

Rails 3.2.8
想做個(gè)實(shí)例，搜一下網(wǎng)上的書，還是不行，那些書最新的2012的都不用命令行做，2011的還是老的命令行方式。根本沒法用，上官網(wǎng)看就是了。

瀏覽器中輸入http://localhost:3000/，熟悉的界面出現(xiàn)
所以ror厚厚的書讀完也沒用，可能動(dòng)手連代碼都沒機(jī)會(huì)敲。
另外也可以到網(wǎng)站http://railsinstaller.org/下載配置好的安裝包，就免去手動(dòng)配置啦。
