I am trying to build a sample application with Go gRPC, but I am unable to generate the code using "protoc"
I have installed the required libraries and Go packages using:
go get -ugo get -u
I have tried setting the path as well, but no luck.
Sample "proto" file:
syntax = "proto3";
package greet;
option go_package="greetpb";
service GreetService{}Error message:
5"protoc-gen-go: program not found or is not executable
--go_out: protoc-gen-go: Plugin failed with status code 1."

There are two ways to install the protobuf compiler. If you're on Ubuntu you can use this:
sudo apt install protobuf-compilerThen of course there's the standard way:
go get -u Here forward it's just adding the path. Assuming when you installed Go you did this,
echo 'export GOPATH=$HOME/Go' >> $HOME/.bashrc
source $HOME/.bashrcNow you can just extend this:
echo 'export PATH=$PATH:$GOPATH/bin' >> $HOME/.bashrc
source $HOME/.bashrcStrangely protoc can't expand ~.
I resolved it by following these steps:
Install the Go library using:
go get -u - Run
vim ~/.bash_profile - Add:
export GO_PATH=~/go export PATH=$PATH:/$GO_PATH/bin - Run
source ~/.bash_profile

6Tannisha Hill indicated that the following package had to be added:
sudo apt install protobuf-compilerIn my case, I also had to add this one:
sudo apt install golang-goprotobuf-devFrom the GitHub repository, this solution has worked for me.
The Go version is go version go1.14.1 Linux/amd64
Add this to .bashrc and source it.
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT:$GOPATH:$GOBINRef.: protoc-gen-go: program not found or is not executable #795
Also try the official solution from grpc.io documentation.
Go plugins for the protocol compiler:
Install the protocol compiler plugins for Go using the following commands:
export GO111MODULE=on # Enable module mode
go get \ Update your PATH so that the protoc compiler can find the plugins:
export PATH="$PATH:$(go env GOPATH)/bin"This worked for me.
0Make sure your GOBIN is set in the PATH variable. Otherwise, you may encounter this problem. Check GOBIN path by running go env and confirm GOBIN is not empty.
If it is empty then try like below
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
protoc --go_out=plugins=grpc:. *.protoGo 1.17+
From
Starting in Go 1.17, installing executables with go get is deprecated. go install may be used instead.
~/.bashrc
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/binInstall
go install go: downloading v1.27.1
go install go: downloading v1.2.0
go: downloading v1.44.0
file.go
protoc --go-grpc_out=. *.protoEnvironment

Use go get to download the following packages:
go get
go get For setting GOPATH and GOROOT, follow the below procedure:
But, first, run go env.
If you see that the Go is not installed, you can install it via Homebrew. If you see the output, then your Go is installed. It shows you all the environments that are set and are not.
If you see empty for GOPATH:
Create any directory anywhere on your computer for Go projects in my case: ~/GO_PROJECTS then export GOPATH=~/GO_PROJECTS.
If you see empty for GOROOT:
Run which go (on my computer: /usr/local/bin/go)
then edit your ~/.zshrc file to add the following line export like this export GOROOT=/usr/local/go.
You can also edit your ~/.zshrc file to add the following line to set up the GOPATH and GOROOT:
If you have installed Go from the original pkg, download from .
export GOPATH=$HOME/dev/go-workspace
export GOROOT=/usr/local/go
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/binIf you have installed Go using Homebrew.
export GOPATH=$HOME/dev/go-workspace
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/binSave and exit your editor. Then, source your ~/.zshrc.
source ~/.zshrcI tried multiple solutions, but at the end I found out that Go environment variables are the actual culprits for this.
If you are on Linux, add these variables in your .bashrc or .bash_profile file.
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT:$GOPATH:$GOBINAnd don't forget to source it after editing (e.g., $source ~/.bashrc).
Many of the other responses address path issues, but if it's not installed, you can install it using the following command:
go install When you run go get -u in Visual Studio Code terminal, and if Visual Studio Code doesn't find $GOPATH and $GOBIN, it will install the package at the default user's home directory /home/$username/go{/bin}
The solution is to move all files in the bin and pkg folders to your current go path (/usr/local/go{/bin}). The go path is the one which contains the go file in the bin folder.
And add this line to the end of the .bashrc file:
export GOPATH=/usr/local/go:$PATH
export GOBIN=/usr/local/go/bin:$PATHThen reboot the computer.
Step 1:
sudo apt install protobuf-compilerStep 2:
go install Step 3:
go install Update your PATH so that the protoc compiler can find the plugins:
export PATH="$PATH:$(go env GOPATH)/bin"NB: Switch to root privileges on your terminal and follow these steps. This got me out of the ditch
- git clone /usr/local/go/bin/src/
- cd src/
- go build
- cp protoc-gen-micro /bin
Happy coding!
0In case someone is facing the same issue nowadays.
Install the Go library using
go get -u Make sure the GOPATH variable is set. In my case I created a folder called gocode, but if your code is located in another folder you have to change it.
export GOPATH=$HOME/gocode
export Path=$Path:$GOPATH/binAfter following these steps, I found another error protoc-gen-go failed :: The import path must contain at least one forward slash ('/') character. To solve this, change the path in the option
syntax = "proto3";
package greet;
option go_package="./greet/greetpb";
service GreetService{}After installing Go, use go get to download the following packages:
$ go get
$ go get
