gvm is a Go version manager. gvm installs a Go version and prints the commands to configure your environment to use it. gvm can install Go binary versions from https://golang.org/dl/ or build it from source. Below are examples for common shells.

bash:

eval "$(gvm 1.17.2)"

cmd.exe (for batch scripts %i should be substituted with %%i):

FOR /f "tokens=*" %i IN ('"gvm.exe" 1.17.2') DO %i

powershell:

gvm --format=powershell 1.17.2 | Invoke-Expression

You can download a binary release of gvm for your specific platform from the releases page. Then just put the binary in your PATH and mark it as executable (chmod +x gvm).

You must adjust the version and platform info in URLs accordingly.

Linux:

# Linux Example (assumes ~/bin is in PATH).
curl -sL -o ~/bin/gvm https://github.com/andrewkroh/gvm/releases/download/v0.3.1/gvm-linux-amd64
chmod +x ~/bin/gvm
eval "$(gvm 1.17.2)"
go version

macOS:

# macOS Example
curl -sL -o /usr/local/bin/gvm https://github.com/andrewkroh/gvm/releases/download/v0.3.1/gvm-darwin-amd64
chmod +x /usr/local/bin/gvm
eval "$(gvm 1.17.2)"
go version

Windows (Powershell):

[Net.ServicePointManager]::SecurityProtocol = "tls12"
Invoke-WebRequest -URI https://github.com/andrewkroh/gvm/releases/download/v0.3.1/gvm-windows-amd64.exe -Outfile C:\Windows\System32\gvm.exe
gvm --format=powershell 1.17.2 | Invoke-Expression
go version

Fish Shell:

Use gvm with fish shell by executing gvm 1.17.2 | source in lieu of using eval.
