Hi everyone,

Small question about the installation of this tool in a Docker project, I try to install it in a nginx:alpine image, the problem is, once go is installed, here's the error that appears:

# go get -u github.com/FiloSottile/mkcert
# github.com/FiloSottile/mkcert
root/go/src/github.com/FiloSottile/mkcert/cert.go:87:19: undefined: x509.MarshalPKCS8PrivateKey
root/go/src/github.com/FiloSottile/mkcert/cert.go:198:18: undefined: x509.MarshalPKCS8PrivateKey
root/go/src/github.com/FiloSottile/mkcert/go110min.go:8:9: undefined: ThisProjectRequiresGo1·10OrHigher
root/go/src/github.com/FiloSottile/mkcert/go110min.go:8:31: invalid identifier character U+00B7 '·'
root/go/src/github.com/FiloSottile/mkcert/main.go:53:52: flag.CommandLine.Output undefined (type *flag.FlagSet has no field or method Output, but does have flag.output)

I've tried to install it several time (after installing additionals tools) but nothing works, the error stay the same, does anyone has already solved the problem ? 🤔

Thanks for the help 😃

Hi! mkcert requires Go 1.10 or higher to compile, and it looks like you are using an out of date version.
