Question content

I'm trying to use gin-swagger to set up OpenAPI documentation on several APIs written in gin. When I install the package in the project path via go install github.com/swaggo/swag/cmd/swag@latest, I cannot run swag init!

swag init

Output:

zsh: command not found: swag

Solution

I realized that the problem is related to GOPATH!

I browsed the ~/go/bin path and saw swag, indicating it was installed correctly. Then, I open the .zshrc file to check the variables as follows:

GOROOT=/usr/local/go
GOPATH=~/.go
PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Next, I corrected GOPATH from GOPATH=~/.go to GOPATH=~/go to fix the problem.

Now, swag init can work.
