<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.

You can remove Go from your system using the steps described in this topic.

|
|
<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>

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.
|

</ul>
