| <h2 id="installing-multiple">Installing multiple Go versions</h2> |
| |
| <p> |
| You can install multiple Go versions on the same machine. For example, you might want to test your code on multiple Go versions. For a list of versions you can install this way, see the <a href="/dl/">download page</a>. |
| </p> |
| |
| <p> |
| <strong>Note:</strong> To install using the method described here, you'll need to have <a href="https://git-scm.com/">git</a> installed. |
| </p> |
| |
| <p> |
| To install additional Go versions, run the <a href="/cmd/go/#hdr-Compile_and_install_packages_and_dependencies"><code>go install</code> command</a>, specifying the download location of the version you want to install. The following example illustrates with version 1.10.7: |
| </p> |
| |
| <pre> |
| $ go install golang.org/dl/go1.10.7@latest |
| $ go1.10.7 download |
| </pre> |
| |
| <p> |
| To run <code>go</code> commands with the newly-downloaded version, append the version number to the <code>go</code> command, as follows: |
| </p> |
| |
| <pre> |
| $ go1.10.7 version |
| go version go1.10.7 linux/amd64 |
| </pre> |
| |
| <p> |
| When you have multiple versions installed, you can discover where each is installed, look at the version's <code>GOROOT</code> value. For example, run a command such as the following: |
| </p> |
| |
| <pre> |
| $ go1.10.7 env GOROOT |
| </pre> |
| |
| <p> |
| To uninstall a downloaded version, just remove the directory specified by its <code>GOROOT</code> environment variable and the goX.Y.Z binary. |
| </p> |

| <p> |
| You can remove Go from your system using the steps described in this topic. |
| </p> |
| |
| <h3 id="linux-mac-bsd">Linux / macOS / FreeBSD</h3> |
| |
| <ol> |
| |
| <li>Delete the go directory. |
| |
| <p> |
| This is usually /usr/local/go. |
| </p> |
| |
| </li> |
| |
| <li>Remove the Go bin directory from your <code>PATH</code> environment variable. |
| |
| <p> |
| Under Linux and FreeBSD, edit /etc/profile or $HOME/.profile. If you installed Go with the macOS package, remove the /etc/paths.d/go file. |
| </p> |
| |
| </li> |
| |
| </ol> |
| |
| <h3 id="windows">Windows</h3> |
| |
| <p> |
| The simplest way to remove Go is via Add/Remove Programs in the Windows control panel: |
| </p> |
| |
| <ol> |
| |
| <li>In Control Panel, double-click <strong>Add/Remove Programs</strong>.</li> |
| <li>In <strong>Add/Remove Programs</strong>, select <strong>Go Programming Language,</strong> click Uninstall, then follow the prompts.</li> |
| |
| </ol> |
| |
| <p> |
| For removing Go with tools, you can also use the command line: |
| </p> |
| |
| <ul> |
| |
| <li>Uninstall using the command line by running the following command: |
| |
| <pre> |
| msiexec /x go{{version}}.windows-{{cpu-arch}}.msi /q |
| </pre> |
| |
| <p> |
| |
| <strong>Note:</strong> Using this uninstall process for Windows will automatically remove windows environment variables created by the original installation. |
| </p> |
| |
| </li> |
| |
| </ul> |
