如何在 Ubuntu 上正确安装 protoc-gen-go？

Question

I managed to download and install Go on Ubuntu. However, I'm currently unable to set up protoc-gen-go properly because my GOPATH and GOROOT are not properly defined. Here's what my GOROOT and GOPATH look like:

export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT:$GOPATH:$GOBIN
export PATH="$PATH:$HOME/.local/bin"
export PATH=$PATH:$GOPATH/bin
export GO_PATH=~/go
export PATH=$PATH:/$GO_PATH/bin

Answer 1

Try to remove all of these lines, and replace them with:

#export GOROOT=/usr/local/go # this should not be needed
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT:$GOPATH:$GOBIN

No need to export PATH so many times..

Also using ~ in export GO_PATH=~/go can cause issues.

Once you add the lines to .bashrc reload your terminal, or execute these same lines in the terminal, so they take effect.
