1. Download the AWS SAM CLI .zip file to a directory of your choice.
2. (Optional) You can verify the integrity of the installer before
installation. For instructions, see Verify the integrity of the AWS SAM CLI
installer.
3. Unzip the installation files into a directory of your choice. The following
is an example, using the sam-installation subdirectory.
NOTE
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
4. Install the AWS SAM 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:

* To begin installation, download the macOS pkg to a directory of your choice:
* x86_64 – aws-sam-cli-macos-x86_64.pkg
* arm64 – aws-sam-cli-macos-arm64.pkg
TO VERIFY THE PACKAGE INSTALLER (OPTIONAL)
* You can verify the integrity of the installer before installation. For
instructions, see Verify the integrity of the AWS SAM CLI installer.
TO INSTALL THE AWS SAM CLI
1. 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">
<plist version="1.0">
<array>
<dict>
<key>choiceAttribute</key>
<string>customLocation</string>
<key>attributeSetting</key>
<string>path-to-my-directory</string>
<key>choiceIdentifier</key>
<string>default</string>
</dict>
</array>
</plist>
2. Save the xml file and verify that its valid by running the following:
$ installer -pkg path-to-pkg-installer \
-target CurrentUserHomeDirectory \
-showChoicesAfterApplyingChangesXML path-to-your-xml-file
The output should display the preferences that will be applied to the AWS
SAM CLI program.
3. Run the following to install the AWS SAM CLI:
$ installer -pkg path-to-pkg-installer \
-target CurrentUserHomeDirectory \
-applyChoiceChangesXML path-to-your-xml-file
# Example output
installer: Package name is AWS SAM CLI
installer: choices changes file 'path-to-your-xml-file' applied
installer: Upgrading at base path base-path-of-xml-file
installer: The upgrade was successful.
TO CREATE A SYMLINK
* To invoke the AWS SAM CLI with the sam command, you must manually create a
symlink between the AWS SAM CLI program and your $PATH. Create your symlink
by modifying and running the following command:
$ sudo ln -s /path-to/aws-sam-cli/sam /path-to-symlink-directory/sam
* sudo – If your user has write permissions to $PATH, sudo is not required.
Otherwise, sudo is required.
* path-to – Path to where you installed the AWS SAM CLI program. For
example, /Users/myUser/Desktop.
* path-to-symlink-directory – Your $PATH environment variable. The default
location is /usr/local/bin.
TO VERIFY A SUCCESSFUL INSTALLATION
* Verify that the AWS SAM CLI has properly installed and that your symlink is
configured by running:
$ which sam
/usr/local/bin/sam
$ sam --version
SAM CLI, version 1.66.0
Homebrew
IMPORTANT
You must have Homebrew installed on your machine. For install instructions, see
Installing Homebrew to use with the AWS SAM CLI.
