In bash file (PHP-FPM.sh), I run this command

I don't know to fix this error :(
Thanks <3

Answer 1

This Error mostly occur when your project is not inside GoPATH to solve this issue use GO111MODULE=auto (Click here for detail)

In Go, The Project is supposed to be at a specific location(GOPATH) to solve this problem Go Modules come into the picture which helps us to run the go program even outside the go path. By Default, Go Language use GoPATH you can change it to GoModules by changing the environment variable GO11MODULE to either auto (will use GO Modules if your project is not inside GoPATH) or on (will always use GO Modules even if your project is at GOPATH)

NOTE: Looking at your project it looks like you have already initilized the Go Modules (presence of go.mod) That's why I didn't suggest initializing go modules (which can be done by running go mod init)

Answer 2

In my case I had the permission GOROOT issue in docker because the "go.mod" and "go.sum" files were not at the correct directory location.
