Everything I read about the vendor directory gives me the understanding that if I have a directory:
$GOPATH/src/vendor
And put my dependencies in there (I am using godeps), when doing go run, go should check in that directory first.
If I run my code in a Docker image I have, this works fine. However now that I try to run the same code on my Windows machine, go simply ignores the vendor/ directory, and fails to find the dependencies.
What am I doing wrong?
main.go:7:2: cannot find package "gopkg.in/alecthomas/kingpin.v2" in any of:
C:\Go\src\gopkg.in\alecthomas\kingpin.v2 (from $GOROOT)
C:\Users\js\dev\my_project\rest\src\gopkg.in\alecthomas\kingpin.v2 (from $GOPATH)
C:\Users\js\dev\go\src\gopkg.in\alecthomas\kingpin.v2
Is the output when I try to do:
go run main.go
A directory vendor/ exists in this directory.
go version go1.7 windows/amd64
The exact commands I run (in windows cmd.exe)
> cd C:\Users\js\dev\my_project\rest\
> set GOPATH=C:\Users\js\dev\my_project\rest\;c:\Users\js\dev\go
> cd src
> dir
...
2016-09-01 23:20 2 923 main.go
...
2016-09-03 01:27 <DIR> vendor
> go run main.go
The reason this did not work is because you are not supposed to put any code directly into the $GOPATH/src/ directory.
The solution is to put your project into a sub-directory like so:
$GOPATH/src/app/*.go
