How to Install Multiple Go Versions

There are times when you might want to try out the latest version for a bit.
The official documentation also explains how to install multiple versions.

https://go.dev/doc/manage-install

This time, I will try installing the unstable version, go1.19beta1.

Check the version of Go that is already installed.

❯❯❯ go version
go version go1.18.3 linux/amd64

First, run the following command.

❯❯❯ go install golang.org/dl/go1.19beta1@latest

Next, run the following command.

❯❯❯ go1.19beta1 download

Let's verify if it is installed.

❯❯❯ go1.19beta1 version
go version go1.19beta1 linux/amd64

Now you can run the new version of Go locally by using go1.19beta1 instead of the go command.

To remove it, run the following commands.

❯❯❯ sudo rm $HOME/go/bin/go1.19beta1

❯❯❯ sudo rm -rf $HOME/sdk/go1.19beta1

That's it.
