英文:
File does not exist error when I run hello.go program
问题
我正在遵循Go文档并尝试运行hello.go。
我使用msi安装程序在Windows 7上安装了go 1.1.2。
我有文件"C:\Go\pkg\tool\windows_386\8g.exe"（请参见下面的dir输出），但当我运行'go.exe run hello.go'时，我收到文件不存在的错误。
请帮忙。谢谢。
C:\>go.exe run hello.go
go build command-line-arguments: exec: "C:\Go\pkg\tool\windows_386g.exe":

C:\>go.exe version
go version go1.1.2 windows/386

从[问题6224][1]中可以看出，如果在运行go.exe之前将环境变量PATHEXT设置为只有一个扩展名，就会出现这个错误。
set PATHEXT=.BATgo run hello.go
> 期望的输出是什么？
没有错误，hello world程序正常运行。
> 实际看到的是什么？
go build command-line-arguments:
exec: "c:\Go\pkg\tool\windows_386\8g.exe": 文件不存在
8g
Windows 7 64位
go版本 go1.1.2 windows/386
在我的电脑上（W7 64位），我有：
set pa
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
一切都正常运行。
> LookPath被调用时使用的是"c:\Go\pkg\tool\windows_386\8g.exe"，而PATHEXT被以一种不好的方式设置，可以说是让LookPath失败了。

英文:
From [issue 6224][1], this error happens if you had the environment variable PATHEXT set to only one extension, before running go.exe.
set PATHEXT=.BATgo run hello.go
> What is the expected output?
no errors and hello world program runs
> What do you see instead?
go build command-line-arguments:
exec: "c:\\Go\\pkg\\tool\\windows_386\g.exe": file does not exist
8g
Windows 7 64bit
go version go1.1.2 windows/386
On my computer (W7 64 bits), I have:
set pa
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
and everything runs just fine.
> LookPath is called with "c:\Go\pkg\tool\windows_386\8g.exe" and the fact that PATHEXT is being set in an evil way let's say, make LookPath fails
