This document describes how to switch between different Go versions when you have multiple Go versions installed on your system.

Prerequisites

• Multiple Go versions installed (e.g., go1.22, go1.24)

Steps

1. Identify the installation paths of your Go versions.

   For example:

   • go1.22: /usr/lib/go-1.22
   • go1.24: /home/xxx/sdk/go1.24.4

2. Modify your shell configuration file.

   The shell configuration file depends on the shell you are using. For example:

   • Bash: ~/.bashrc or ~/.bash_profile
   • Zsh: ~/.zshrc
   • Fish: ~/.config/fish/config.fish

3. Set the GOROOT and PATH environment variables.

   Add the following lines to your shell configuration file, replacing the paths with the actual installation paths of your desired Go version:

   1 2	export GOROOT=/path/to/go/version export PATH=$GOROOT/bin:$PATH

   For Fish shell, use:

   1 2	set -gx GOROOT /path/to/go/version set -gx PATH $GOROOT/bin $PATH

   For example, to switch to go1.24 in Fish shell, add the following lines to ~/.config/fish/config.fish:

   1 2	set -gx GOROOT /home/xxx/sdk/go1.24.4 set -gx PATH /home/xxx/sdk/go1.24.4/bin $PATH

4. Reload your shell configuration.

   Run the following command to reload your shell configuration:

   1 2 3

   source ~/.bashrc # For Bash source ~/.zshrc # For Zsh source ~/.config/fish/config.fish # For Fish

5. Verify the Go version.

   Run the following command to verify that you have successfully switched to the desired Go version:

   1	go version

   The output should show the Go version you selected.

Example

To switch to go1.24 in Fish shell, follow these steps:

1. Edit ~/.config/fish/config.fish and add the following lines:

   1 2	set -gx GOROOT /home/xxx/sdk/go1.24.4 set -gx PATH /home/xxx/sdk/go1.24.4/bin $PATH

2. Run source ~/.config/fish/config.fish to reload the shell configuration.

3. Run go version to verify that you are using go1.24.4.
