Download the update the lock file and vendor directory
>dep ensure -update

Install Go on CentOS
>wget https://dl.google.com/go/go1.10.linux-amd64.tar.gz
Unzip and place in the working directory
>sudo ln -s ~/tool/go-1.10 /opt/go-1.10
>sudo ln -s /opt/go-1.10 /opt/go

GOROOT=/opt/go
GOPATH=/home/ec2-user/users/carl/monitor-water/restful_go_api

export GOROOT
export GOPATH

PATH=$PATH:/opt/go/bin

Who is doing this un professional things on our production server….
>type go
go is aliased to `git checkout'
>unalias go
>type go
go is /opt/go/bin/go

Check version
>go version
go version go1.10 linux/amd64

Install dep on the machine
>curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
It will install a dep in bin directory

>bin/dep version
dep:
version : devel
build date :
git hash :
go version : go1.10
go compiler : gc
platform : linux/amd64

Run the download command
>dep ensure
>dep ensure -update

Then the build will work
>go install sillycat.com/restful_go_api

RaspberryPi Installation
>wget https://dl.google.com/go/go1.10.linux-armv6l.tar.gz
Unzip and place that in working directory

Prepare the directory
>sudo ln -s /home/carl/work /opt/work
>mkdir /opt/work/go/bin

Add these in the PATH
PATH="/opt/go/bin:$PATH"
export GOROOT="/opt/go"
export GOPATH="/opt/work/go"

Check go version
>go version
go version go1.10 linux/arm

Try to install dep
>curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
Architecture armv7l is not supported by this installation script

In my working directory
>pwd

Try to get the source
>go get -u github.com/golang/dep/cmd/dep

Install that to bin directory
>go install github.com/golang/dep/cmd/dep

It is there after installation
>ls -l bin
total 11068
