For information on managing a currently installed version of the AWS SAMÂ CLI, including how to upgrade, uninstall, or manage nightly builds, see Managing AWS SAMÂ CLI versions.
Is this your first time installing the AWS SAMÂ CLI?Complete all prerequisites in the previous section before moving forward. This includes:
Signing up for an AWS account.
Setting up secure access to AWS.
Creating an access key ID and secret access key.
Installing the AWS CLI.
Configuring AWS credentials.
Starting September 2023, AWS will no longer maintain the AWS managed Homebrew installer for the AWS SAMÂ CLI (aws/tap/aws-sam-cli
). If you use Homebrew to install and manage the AWS SAMÂ CLI, see the following options:
To install the AWS SAMÂ CLI, follow the instructions for your operating system.
Download the AWS SAMÂ CLI .zip file to a directory of your choice.
(Optional) You can verify the integrity of the installer before installation. For instructions, see Optional: Verify the integrity of the AWS SAMÂ CLI installer.
Unzip the installation files into a directory of your choice. The following is an example, using the sam-installation
subdirectory.
If your operating system doesn't have the built-in unzip command, use an equivalent.
$
unzip aws-sam-cli-linux-x86_64.zip -d sam-installation
Install the AWS SAMÂ CLI by running the install
executable. This executable is located in the directory used in the previous step. The following is an example, using the sam-installation
subdirectory:
$
sudo ./sam-installation
/install
Verify the installation.
$
sam --version
To confirm a successful installation, you should see an output that replaces the following bracketed text with the latest available version:

/aws-sam-cli/sam /path-to-symlink-directory
/sam
sudo
â If your user has write permissions to $PATH
, sudo is not required. Otherwise, sudo is required.
path-to
â Path to where you installed the AWS SAMÂ CLI program. For example, /Users/myUser/Desktop
.
path-to-symlink-directory
â Your $PATH
environment variable. The default location is /usr/local/bin
.
Verify that the AWS SAMÂ CLI has properly installed and that your symlink is configured by running:
$
which sam
/usr/local/bin/sam

Download the macOS pkg
to a directory of your choice:
Determine an installation directory that you have write permissions to. Then, create an xml
file using the template and modify it to reflect your installation directory. The directory must already exist.
For example, if you replace path-to-my-directory
with /Users/myUser/Desktop
, the aws-sam-cli
program folder will be installed there.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

sam --version
After successful installation of the AWS SAMÂ CLI, you should see output like the following:
SAM CLI, <latest version>
Enable long paths (Windows 10 and newer only).
ImportantThe AWS SAMÂ CLI might interact with filepaths that exceed the Windows max path limitation. This may cause errors when running sam init
due to Windows 10 MAX_PATH limitations. To resolve this issue, the new long paths behavior must be configured.
To enable long paths, see Enable Long Paths in Windows 10, Version 1607, and Later in the Microsoft Windows App Development Documentation.
Install Git.
To download sample applications using the sam init
command, you must also install Git. For instructions, see Installing Git.
In some cases, to provide permissions for the ec2-user
to access the Docker daemon, you might have to reboot your instance. If you receive this error, try rebooting your instance.
If you receive this error, your shell can't locate the AWS SAMÂ CLI executable in the path. Verify the location of the directory where you installed the AWS SAMÂ CLI executable, and then verify that the directory is on your path.
AWS SAMÂ CLI error: "/lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/local/aws-sam-cli/dist/libz.so.1)"If you receive this error, you're using an unsupported version of Linux, and the built-in glibc version is out of date. Try either of the following:
