i see this often when working with mysql or mysql2, i tried to install ffi but it makes no difference, could you please help solving this issue
我经常在使用mysql或mysql2时看到这个，我试图安装ffi，但没有区别，请你帮我解决这个问题
i tried gem install ffi, bundle install ffi i tried many stuff, just would not work! when do rake db:create i will see the error, i have the latest rails installer if i use ruby installer instead, i'll get many other errors like: you need the dev toolkit to build this gem and i install the toolkit and still the the error therefore i prefer to stick with rails installer,
我试过gem install ffi，捆绑安装ffi我试过很多东西，就行不通！什么时候rake db：create我会看到错误，我有最新的rails安装程序，如果我使用ruby安装程序，我会得到许多其他错误，如：你需要dev工具包来构建这个gem，我安装工具包仍然错误因此我更喜欢坚持使用rails安装程序，
EDIT:
编辑：
lets say i typed bundle install mysql i see the error: make sure that ffi installation succeeds before you continue or something like that, the thing is, if i don't solve ffi error i'll be stuck with sqlite, because i bet that mongodb, couchdb, mysql, mysql2, postgeres, whatever... all need ffi, i don't know what ffi is but it's seems to be very important thing
让我说我键入捆绑安装mysql我看到错误：确保ffi安装成功之前你继续或类似的事情，事情是，如果我不解决ffi错误我将被卡住sqlite，因为我打赌， mongodb，couchdb，mysql，mysql2，postgeres，无论......都需要ffi，我不知道ffi是什么，但它似乎是非常重要的事情

I've never had an issue with ffi myself (in fact I hadn't even heard of it before your post), although I did have bizarre gem issues when working on Windows.
我自己从来没有遇到过ffi的问题（实际上我在你的帖子之前我甚至没有听说过），尽管我在Windows上工作时确实有奇怪的宝石问题。
Your problem seems to be this:
你的问题似乎是这样的：
C:/Documents and Settings/Administrator/Desktop/ror/selvista/mysql2/ruby/1.9.1/gems/ffi-1.0.11
C：/ Documents and Settings / Administrator / Desktop / ror / selvista / mysql2 / ruby / 1.9.1 / gems / ffi-1.0.11
In particular, there's a line in your error code:
特别是，您的错误代码中有一行：
configure: WARNING: Libtool does not cope well with whitespace in 'pwd'
I think you need to move your ror folder somewhere else, like C:\ror, something without spaces in it.
我认为你需要将你的ror文件夹移动到其他地方，比如C：\ ror，里面没有空格的东西。
If you look higher up:
如果你看起来更高：
Makefile:160: warning: overriding commands for target 'C:/Documents'
It thinks your folder is just C:/Documents
它认为你的文件夹只是C：/ Documents
