How does the install command work?

Question

go

I'm watching one lecture on creating web applications in the go language and I don't understand one moment. Perhaps this is not even so much related to the language, but to the bash commands. The following folder structure C:\code\src\firstapp\main.go is created there, after which, being in the C:\code> directory, the go install firstapp command goes and the C:\code\bin directory appears with the firstapp.exe file inside. I'm trying to repeat this, the only difference is that I have all this on my desktop in the folder C:\Users\zz\Desktop\go_project\web\
As a result, I get some kind of error
can't load package: package firstapp: cannot find package "firstapp" in any of:
C:\Go\src\firstapp (from $GOROOT)
C:\gopath\src\firstapp (from $GOPATH)
The $GOROOT and $GOPATH variables are set to the C:\Go\ and C:\gopath directories, respectively. Can you please tell me if these variables need to be changed, if so, where should they point to?

Answer 1

You do not need to change the variables, but move your project inside C:\gopath\src\
If you put the files containing the main package in the C:\gopath\src\firstapp folder, you can build the project throughgo build firstapp
