<p class="hideFromDownload">
|
|
Choose the archive file appropriate for your installation.
|
|
For instance, if you are installing Go version 1.2.1 for 64-bit x86 on Linux,
|
|
the archive you want is called <code>go1.2.1.linux-amd64.tar.gz</code>.
|

</p>

<p>
|
|
(Typically these commands must be run as root or through <code>sudo</code>.)
|
|
</p>
|
|
|
|
<p>
|
|
Add <code>/usr/local/go/bin</code> to the <code>PATH</code> environment
|
|
variable. You can do this by adding this line to your <code>/etc/profile</code>
|
|
(for a system-wide installation) or <code>$HOME/.profile</code>:
|
|
</p>
|
|
|
|
<pre>
|
|
export PATH=$PATH:/usr/local/go/bin
|
|
</pre>
|
|
|
|
<p>
|
|
<b>Note</b>: changes made to a <code>profile</code> file may not apply until the
|
|
next time you log into your computer.
|
|
To apply the changes immediately, just run the shell commands directly
|
|
or execute them from the profile using a command such as
|
|
<code>source $HOME/.profile</code>.

|
|

The package should put the <code>/usr/local/go/bin</code> directory in your

By default, the installer puts the Go distribution in <code>c:\Go</code>.

<h2 id="testing">Test your installation</h2>
|
|
|
|
<p>
|
|
Check that Go is installed correctly by building a simple program, as follows.
|
|
</p>
|
|
|
|
<p>
|
|
Create a file named <code>hello.go</code> that looks like:
|
|
</p>
|
|
|
|
<pre>
|
|
package main
|
|
|
|
import "fmt"
|
|
|
|
func main() {
|
|
fmt.Printf("hello, world\n")
|
|
}
|
|
</pre>
|
|
|
|
<p>
|
|
Then build it with the <code>go</code> tool:
|
|
</p>
|
|
|
|
<pre class="testUnix">
|
|
$ <b>go build hello.go</b>
|
|
</pre>
|
|
|
|
<pre class="testWindows">
|
|
C:\Users\Gopher\go\src\hello> <b>go build hello.go</b>
|
|
</pre>
|
|
|
|
<p>
|
|
The command above will build an executable named
|
|
<code class="testUnix">hello</code><code class="testWindows">hello.exe</code>
|
|
in the current directory alongside your source code.
|
|
Execute it to see the greeting:
|
|
</p>
|
|
|
|
<pre class="testUnix">
|
|
$ <b>./hello</b>
|
|
hello, world
|
|
</pre>
|
|
|
|
<pre class="testWindows">
|
|
C:\Users\Gopher\go\src\hello> <b>hello</b>
|
|
hello, world
|
|
</pre>
|
|
|
|
<p>
|
|
If you see the "hello, world" message then your Go installation is working.
|
|
</p>
|
|
|
|
<p>
|
|
Before rushing off to write Go code please read the
|
|
<a href="/doc/code.html">How to Write Go Code</a> document,
|
|
which describes some essential concepts about using the Go tools.

<h2 id="extra_versions">Installing extra Go versions</h2>
|
|
|
|
<p>
|
|
It may be useful to have multiple Go versions installed on the same machine, for
|
|
example, to ensure that a package's tests pass on multiple Go versions.
|
|
Once you have one Go version installed, you can install another (such as 1.10.7)
|
|
as follows:
|
|
</p>
|
|
|
|
<pre>
|
|
$ go get golang.org/dl/go1.10.7
|
|
$ go1.10.7 download
|
|
</pre>
|
|
|
|
<p>
|
|
The newly downloaded version can be used like <code>go</code>:
|
|
</p>
|
|
|
|
<pre>
|
|
$ go1.10.7 version
|
|
go version go1.10.7 linux/amd64
|
|
</pre>
|
|
|
|
<p>
|
|
All Go versions available via this method are listed on
|
|
<a href="https://godoc.org/golang.org/dl#pkg-subdirectories">the download page</a>.
|
|
You can find where each of these extra Go versions is installed by looking
|
|
at its <code>GOROOT</code>; for example, <code>go1.10.7 env GOROOT</code>.
|
|
To uninstall a downloaded version, just remove its <code>GOROOT</code> directory
|
|
and the <code>goX.Y.Z</code> binary.
|
|
</p>
|
|
|
|
|
|
<h2 id="uninstall">Uninstalling Go</h2>
|
|
|
|
<p>
|
|
To remove an existing Go installation from your system delete the
|
|
<code>go</code> directory. This is usually <code>/usr/local/go</code>
|
|
under Linux, macOS, and FreeBSD or <code>c:\Go</code>
|
|
under Windows.
|
|
</p>
|
|
|
|
<p>
|
|
You should also remove the Go <code>bin</code> directory from your
|
|
<code>PATH</code> environment variable.
|
|
Under Linux and FreeBSD you should edit <code>/etc/profile</code> or
|
|
<code>$HOME/.profile</code>.
|
|
If you installed Go with the <a href="#macos">macOS package</a> then you
|
|
should remove the <code>/etc/paths.d/go</code> file.
|
|
Windows users should read the section about <a href="#windows_env">setting
|
|
environment variables under Windows</a>.
