英文:
Go environment variables stay unchanged after setting
问题
我通过观看在线教程开始学习Go编程。我使用的是Windows命令提示符。然而，在我输入set GOOS = darwin然后使用go env打印环境变量时，GOOS并没有被设置为GOOS=darwin，而是仍然保持默认值GOOS=windows。
这是我得到的结果。有人可以告诉我我在哪里出错了，以至于无法更改GOOS吗？
C:\GoPath\src\palindrome>set GOOS = darwin
C:\GoPath\src\palindrome>go env
set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
英文:
I start learning Go programming by watching online tutorials. I use Windows command prompt. However, after I typed set GOOS = darwin then used go env to print environment variables, GOOS was not set to GOOS=darwin but still GOOS=windows as default.
Here is what I got. Could someone tell me where I went wrong such that I cannot make change on GOOS?
C:\GoPath\src\palindrome>set GOOS = darwin
C:\GoPath\src\palindrome>go env
set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows

“变量名或字符串周围的任何额外空格都不会被忽略，SET 命令不像许多其他脚本语言那样容忍额外的空格。”
将 set GOOS = darwin 改为 set GOOS=darwin，即与 go env 输出中的格式相同。
英文:
"Any extra spaces around either the variable name or the string, will not be ignored, SET is not forgiving of extra spaces like many other scripting languages."
Change set GOOS = darwin to set GOOS=darwin - i.e., the same format you see in the output of go env.
