I am getting this error when I tried to run an example helloworld code I got onlie.

compile: version "go1.9" does not match go tool version "go1.9.1"

My computer has go1.9.1. What does the error mean and how can I fix this?

If you are installing using OSX homebrew you may need to set the $GOROOT in your .bashrc, .zshrc, etc:

export GOROOT=/usr/local/opt/go/libexec

I had the same error this morning when I updated from 1.9 -> 1.9.1 though according to several post the $GOROOT shouldn't have to be set and I had not set it until today. This may be a bug?

in case you are using mac with homebrew, just run:

brew cleanup


to clean all the legacy package, this fixed my problem.

This error happens when you forgot to delete previous golang install ... just delete its directory ... so identify go install location ... on linux issue

type go

typical output is

go is hashed (/usr/local/go/bin/go)

so just remove its grandparent directory ( go install not just its binary )

sudo rm -rf /usr/local/go   #  NOTE this is not /usr/local/go/bin/go

now just install go and you'll be fine

In mac OS , if you downloaded and installed go package without brew, running brew update commands will cause this problem to occur
for fix this problem you can do :
brew uninstall --ignore-dependencies go
uninstalling go from brew will fix problem

For Windows delete the GOROOT System variables in the Enviroment Variables and restart the PC.

This is a mismatch between the GOROOT environment variable and the default path to your go command. One or the other needs to be changed; the one that needs to be changed depends on the specific setup on your computer. You could determine this by updating your Go to the latest version using your preferred method, running either which go (on Linux/macOS/BSD) or where go (on Windows), and then checking which of the files listed has the newer timestamp.

Linux/macOS/BSD

• To change the GOROOT to match the default path of your go command, run type go and strip off the /bin/go part at the end to yield the directory path containing your Go installation. Then, add it to your .bashrc or other appropriate init file like this:

export GOROOT=/path/to/go-installation


• To instead change the go command path to match your GOROOT, add this to the bottom of your init file:

export PATH="${GOROOT}/bin:${PATH}"


Windows

• To change the GOROOT to match the default path of your go command, run where go take the first line of output, and strip off the bingo.exe part at the end. Then, go to "Edit the system environment variables" in Settings, click "Environment Variables...", find the "GOROOT" variable and edit to read the path you created earlier.




• To instead change the go command path to match your GOROOT, first save the output of echo %GOROOT%bin. Then, go to "Edit the system environment variables" in Settings, click "Environment Variables...", and find the
  find the "Path" row in the bottom pane, click New, put in the path you created earlier, and finally click Move Up until it's at the top.

All

You'll need to open up a new command prompt to see the effects.
