在Windows 7中设置环境变量
我试图在Windows 7中设置我的环境变量，以便我可以从命令行调用prolog。我在系统设置下进入环境变量，并编辑它，使其看起来像这样。
I am trying to set my environment variable in windows 7 so that I can call prolog from the command line. I went into the environment variables under system settings, and edited it so that it looks like this.
C:\Python27;C:\Program Files (x86)\Notepad++;C:\Program Files\pl\bin\prolog;
我不知道我在这里做错了，因为我不断收到消息
I'm not sure what I did wrong here, as I keep getting the message
prolog is not recognized as an internal or external command, operable program or batch file
Python和Notepad ++的工作方式都很好，我有两次检查，以确保我的路径名是正确的。我DID将prolog可执行文件的名称从swipl-win更改为prolog，但这不应该有所作为，因为我也使用python（python更改为python27）。我是否缺少明显的东西？
Both Python and Notepad++ work just fine the way I have them, and I have double checked to make sure my path name is correct. I DID change the name of the prolog executable from swipl-win to prolog, but that shouldn't make a difference, as I did this with python as well (python changed to python27). Am I missing something blatantly obvious?
是 prolog （可执行文件）里面还有一个叫做prolog的文件夹？如果它位于bin中，则您的路径应为：
Is prolog (the executable) inside a folder also called "prolog"? If it's inside "bin", your path should be:
C:\Python27;C:\Program Files (x86)\Notepad++;C:\Program Files\pl\bin;
（可能是这样，因为在我的系统中 - 我在Windows XP中有Swi-Prolog是一个名为bin的文件夹，没有子文件夹，可执行文件 plwin.exe 里面）
(that's probably the case, since in my system - I have Swi-Prolog in Windows XP - there is a folder called "bin", no subfolders, with the executable plwin.exe inside it)
