Ruby on Rails - Windows 7 上的新安装但无法运行 ruby 命令，路径有问题吗？
我刚刚在我的新计算机上安装了 ruby on Rails（我之前使用的是 instantrails），我正在尝试完成所有设置。
我运行的是 Windows 7。所以我按照本教程中的说明进行操作。

我猜问题是步骤 3
“将新安装的 bin 目录添加到 Windows 系统中的路径：打开 Windows 资源管理器- >右键单击计算机图标->在控制面板主页中选择“高级系统设置”，然后单击“环境变量”按钮->在系统变量中单击“新建”并添加新的系统变量，如下所示： ： RUBY_HOME ，变量值： C:\Ruby，然后将其添加到路径中，并将分号后面的 bin 添加到“Path”变量，如下所示： C:\Program Files\Common Files\Adobe\AGL;%JAVA_HOME %\bin;%ANDROID_HOME%\tools;%RUBY_HOME%\bin"
我设置创建了系统变量，但是当我尝试在应用程序的主目录中运行 script/generate 时，出现错误
“Ruby：没有这样的文件或目录--script/generate”
我检查了应用程序目录，脚本文件夹就在那里。如何从控制面板运行“ruby script/generate”命令？
我猜测这是路径问题，但我不知道有什么方法可以检查以找出问题所在。
I just installed ruby on rails on my new computer ( I was using instantrails before) and I'm trying to get everything setup.
Im running Windows 7. So I followed the instructions from this tutorial.
http://blogupstairs.com/ruby-on-rails/installing-ruby-on-rails-on-windows-7/
The problem i'm guessing is step 3
"Add the newly installed bin directory to your path in your windows system : Open windows explorer-> right click the icon computer-> choose Properties -> in the contol panel Home, Click Advanced system settings and then click Envitonment Variables button->in the system variables click new and add new system variables like this : Variable name : RUBY_HOME , Variable Value : C:\Ruby, after that add it in to the path and add the bin after a semicolon to the “Path” variable like this : C:\Program Files\Common Files\Adobe\AGL;%JAVA_HOME%\bin;%ANDROID_HOME%\tools;%RUBY_HOME%\bin"
I set created the system variables but when I try to run script/generate in the main directory of my app I get the error
"Ruby: no such file or directory --script/generate"
I checked the apps directory and the script folder is in there. How can I run the "ruby script/generate" commands from the control panel?
I was guessing it was something with the path but I dont know any ways to check to find out whats going wrong.

您使用的是 Rails 3.0+ 吗？在此版本的 Rails 及更高版本中，script/* 文件夹已被弃用，取而代之的是
railsgenerate、railsserver等。请参阅 此处。Are you using Rails 3.0+? In this version of rails and up, the script/* folder has been deprecated in favor of
rails generate,rails server, etc. See here.在 99.99999% 的情况下，如果计算机告诉您在特定位置找不到文件，那是因为该文件不在该特定位置。
那么，当前目录中名为
script的目录中是否真的存在一个名为generate的文件？In 99.99999% of all cases, if a computer tells you that it cannot find a file at a specific location, it is because that file is not at that specific location.
So, is there actually a file named
generatein a directory namedscriptin the current directory?我最近也在我的“干净”Win7 上安装了 RoR。
你使用什么IDE？
我建议尝试 JRuby 与 NetBeans/RubyMine：
系统环境设置中的路径...，至于命令，正如 Nuclearsandwitch 提到的，Rails 3 中没有
script/generate或script/server。只需确保您在目录中你的 Rails 应用程序，然后尝试运行rails 服务器它应该可以工作:-)。I have recently installed RoR on my "clean" Win7 as well.
What IDE are you using?
I suggest trying JRuby with NetBeans/RubyMine:
pathin system environment settings...,As for the commands, as Nuclearsandwitch mentioned, there is no
script/generateorscript/serverin Rails 3. Just make sure you in the directory with your Rails app and then try runningrails server. It should work :-)
