Answer 1

If you're using Fedora, ensure that the package "protoc-gen-go" is installed, and it's binary is in your shel PATH.

$sudo dnf install protoc-gen-go -y

Answer 2

What I did to solve this was:

copy protoc-gen-go from the go bin folder in go workspace to /usr/local/bin/

run your command as before in your case "protoc --go_out=../cloud/ *.proto"

Answer 3

On Ubuntu 18.04, this is verified working to solve this issue:

sudo apt-get install golang-goprotobuf-dev

Answer 4

How I solved:

1. Add $GOPATH/bin to PATH by running export PATH=$PATH:$GOPATH/bin
2. add export GOPATH=$(go env GOPATH) above export PATH=$PATH:$GOPATH/bin line inside the .bash_profile file.
3. run go get -u for the required packages again.
4. run the code protoc --go_out=../cloud/ *.proto in your case.

Answer 5

Using

$ go get -u github.com/golang/protobuf/{proto,protoc-gen-go}

is more safe than using

$ sudo apt-get install golang-goprotobuf-dev

Because the latest protoc-gen-go is using the lib github.com/golang/protobuf/proto, but protoc-gen-go in apt-get using the lib code.google.com/p/goprotobuf/proto which didn't exist now.

Answer 6

Ensure that your path to proton-gen-go in your PATH variable is absolute (i.e. /Users/me/go/bin instead of ~/go/bin.

Apparently protoc does not know how to expand ~.
