我一直在尝试在我的12系统上安装lpng142.对我来说似乎是一个问题.我收到这个错误
[root@localhost lpng142]# ./configure
bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory
[root@localhost lpng142]#
我该如何解决？该/etc/fstab文件中:

devpts …我最近在fedora 12中安装了rails.我也是linux新手.在Windows 7上一切正常.但我在linux中面临很多问题.请帮忙!
我已经安装了所有必需品,以使基本脚本/服务器启动并运行.我在尝试脚本/服务器时弹出boot.rb时出现此错误.我想在此提供的一些细节:
安装rails,ruby和gem的目录,
[vineeth@localhost my_app]$ which ruby
/usr/local/bin/ruby
[vineeth@localhost my_app]$ which rails
/usr/bin/rails
[vineeth@localhost my_app]$ which gem
/usr/bin/gem
当我运行脚本/服务器时,这就是错误.
[vineeth@localhost my_app]$ script/server
./script/../config/boot.rb:9:in `require': no such file to load -- rubygems (LoadError)
from ./script/../config/boot.rb:9
from script/server:2:in `require'
from script/server:2
PATH文件看起来像这样
[vineeth@localhost my_app]$ cat ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH="/usr/local/bin:/usr/local/sbin:/usr/bin/ruby:$PATH"
我想这与PATH文件有关.让我知道我需要在这里改变什么.如果我还有其他变化,请告诉我.
我刚刚在Windows机器上安装了ruby 1.9.2,Backspace或任何其他箭头键都不起作用.只有当我在Git Bash控制台上打开IRB时才会发生这种情况.但它在Windows控制台上运行良好.对此有何帮助？
注意:IRB在早期版本的ruby的两个控制台上运行良好.
我在视图中遇到了一些开源代码,其t()标签类似于HTML转义序列h().
<%= f.label :password, t(:password, :scope => "activerecord.attributes.user") -%>
什么t()意思？
这些错误意味着什么？

在Rails 2.3.8中包含XML和HTML以在脚手架中呈现视图(我不明白这是什么,因为我在使用Rails 2.0.2的训练期间从未遇到过这种情况)
在gitorious源目录中,除了Controllers,Models,Views和Helpers之外,还有两个目录,即Processors和Metals.我不明白它们的意义是什么.
广泛使用.yml文件.这些是为了什么？在rails 2.0.2中,我遇到的只是database.yml.现在,在功勋,我看到gitorious.yml.这些都是如此定制的？我的意思是,rails app(控制器,模型等)如何与gitorious.yml进行通信？
关于所有这些问题,如何将一两个级别向上移动,称自己为"Rails新手程序员"中的"中级Rails程序员"？如何在所有即将到来的Rails过渡中保持新api,弃用的更新？
我正在尝试将Rspec 1.3.1用于我的rails应用程序,它运行在2.3.8上.我可以用stub_model方法"存根"模型.但是当我打电话时mock_model,事情就出错了,这就是我得到的堆栈跟踪
