How to Uninstall Go?

Update August 2019

Found the official uninstall docs worked as expected (on Mac OSX).

$ which go
/usr/local/go/bin/go

In summary, to uninstall:

$ sudo rm -rf /usr/local/go
$ sudo rm /etc/paths.d/go

Then, did a fresh install with homebrew using brew install go. Now, i have:

 $ which go
/usr/local/bin/go

I'm using Ubuntu. I spent a whole morning fixing this, tried all different solutions, when I type go version, it's still there, really annoying... Finally this worked for me, hope this will help!

sudo apt-get remove golang-go
sudo apt-get remove --auto-remove golang-go

On a Mac-OS system

1. If you have used an installer, you can uninstall golang by using the same installer.
2. If you have installed from source

   rm -rf /usr/local/go
   rm -rf $(echo $GOPATH)
   

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bash_profile and run

source ~/.bash_profile

On a Linux system

rm -rf /usr/local/go
rm -rf $(echo $GOPATH)

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bashrc and run

source ~/.bashrc

For Windows 10:

1. Go to Apps in the Settings App.
2. Look for Go Programming Language * in the list and uninstall it.
3. Remove C:\Go\bin from your PATH environment variable (only if you don't plan on installing another version of golang)

From the official install page -

To remove an existing Go installation from your system delete the go directory. This is usually /usr/local/go under Linux, macOS, and FreeBSD or c:\Go under Windows.

You should also remove the Go bin directory from your PATH environment variable. Under Linux and FreeBSD you should edit /etc/profile or $HOME/.profile. If you installed Go with the macOS package then you should remove the /etc/paths.d/go file. Windows users should read the section about setting environment variables under Windows.

Use this command to uninstall Golang for Ubuntu.

This will remove just the golang-go package itself.

sudo apt-get remove golang-go

Uninstall golang-go and its dependencies:

sudo apt-get remove --auto-remove golang-go

sudo apt-get remove golang-go
sudo apt-get remove --auto-remove golang-go

This is perfect for Ubuntu 18.18

On a Mac-OS Catalina

1. need to add sudo before rm -rf /usr/local/go sudo rm -rf /usr/local/go otherwise, we will run into permission denial.

2. sudo vim ~/.profile or sudo ~/.bash_profile remove export PATH=$PATH:$GOPATH/BIN or anything related to go lang

3. If you use Zsh shell, then you need to remove the above line to ~/.zshrc file.

Hope it helps you :)

I just have to answer here after reading such super-basic advice in the other answers.

For MacOS the default paths are:

1. /user/bracicot/go (working dir)
2. /usr/local/go (install dir)

When uninstalling remove both directories.
If you've installed manually obviously these directories may be in other places.

One script I came across installed to /usr/local/.go/ a hidden folder because of permissioning... this could trip you up.

In terminal check:

echo $GOPATH
echo $GOROOT
#and
go version

For me after deleting all go folders I was still getting a go version.

Digging through my system path echo $PATH

/Users/bracicot/google-cloud-sdk/bin:/usr/local/bin:

revealed some places to check for still-existing go files such as /usr/local/bin

Another user mentioned: /etc/paths.d/go

You may also want to remove GOPATH and GOROOT environment variables.
Check .zshsrc and or .bash_profile.
Or you can unset GOPATH and unset GOROOT

To uninstall go on MacOS, do this: On the terminal type which go it will; return a path like this /usr/local/go/bin/go Go to the root folder of go which is /usr/local/go/ and type on the terminal rm -rf /usr/local/go/ . you may get permission denied depending on your system setup, so the command should be prefixed with sudo like this

sudo rm -rf /usr/local/go/

It will request for your password, just enter it.

On linux we can do like this to remove go completely:

rm -rf "/usr/local/.go/"
rm -rf "/usr/local/go/"

These two command remove go and hidden .go files. Now we also have to update entries in shell profile.

Open your basic file. Mostly I open like this sudo gedit ~/.bashrc and remove all go mentions.

You can also do by sed command in ubuntu

sed -i '/# GoLang/d' .bashrc
sed -i '/export GOROOT/d' .bashrc
sed -i '/:$GOROOT/d' .bashrc
sed -i '/export GOPATH/d' .bashrc
sed -i '/:$GOPATH/d' .bashrc

It will remove Golang from everywhere. Also run this after running these command

source ~/.bash_profile

Tested on linux 18.04 also. That's All.

In MacOS, you can just do it with brew:

brew uninstall go
brew install go
brew upgrade go
