Mac Update Python3

I thought I might update this for 2020. As of RHEL 7.7, python-devel is not available in EPEL, it has been retired by Fedora Project. All I wanted for today was the python h files, and this got me there: # yum install python3-devel.x8664 -enablerepo=rhel-7-server-optional-rpms. Windows users: If installing Python 3.5.1 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries. Windows users: There are now 'web-based' installers for Windows platforms; the installer will download the needed software components at installation time. WARNING: for a modern macOS (2019) this can install python3, and for python2 you really need to do: brew install [email protected] Install python3: brew install python3 UPDATE: Python 3. If you install python3, pip will be installed automatically. Brew install python3 NEW 2019: now to use pip version 3, use pip3, or you can execute: python3, to.

This is a 'false positive': the file does not contain any malware. We build it ourselves, from source, on a known-clean system. We've asked that this false positive report be removed, and expect action soon. In the meantime, please don't be alarmed to see this warning when installing Python 3.5.2, or when scanning any earlier version of 3.5.

For the macOS platform, you can install the Azure CLI with homebrew package manager. Homebrew makes it easy to keep yourinstallation of the CLI update to date. The CLI package has been tested on macOS versions 10.9 and later.

The current version of the Azure CLI is 2.21.0. For information about the latest release, see the release notes. To find your installed version and see if you need to update, run az version.

Install with Homebrew

Homebrew is the easiest way to manage your CLI install. It provides convenient ways to install, update, and uninstall.If you don't have homebrew available on your system, install homebrew before continuing.

You can install the CLI by updating your brew repository information, and then running the install command:


The Azure CLI has a dependency on the Homebrew python3 package, and will install it.The Azure CLI is guaranteed to be compatible with the latest version of python3published on Homebrew.

You can then run the Azure CLI with the az command. To sign in, use az login command.

  1. Run the login command.

    If the CLI can open your default browser, it will do so and load an Azure sign-in page.

    Otherwise, open a browser page at and enter theauthorization code displayed in your terminal.

    If no web browser is available or the web browser fails to open, use device code flow with az login --use-device-code.

  2. Sign in with your account credentials in the browser.

To learn more about different authentication methods, see Sign in with Azure CLI.



If you encounter a problem when installing the CLI through Homebrew, here are some common errors. If you experience a problem not covered here, file an issue on github.

Completion is not working

The Homebrew formula of Azure CLI installs a completion file named az in the Homebrew-managed completions directory (default location is /usr/local/etc/bash_completion.d/). To enable completion, please follow Homebrew's instructions here.

Unable to find Python or installed packages

There may be a minor version mismatch or other issue during homebrew installation. The CLI doesn't use a Python virtual environment, so it relies on findingthe installed Python version. A possible fix is to install and relink the python3 dependency from Homebrew.

CLI version 1.x is installed

If an out-of-date version was installed, it could be because of a stale homebrew cache. Follow the update instructions.

Proxy blocks connection

You may be unable to get resources from Homebrew unless you have correctly configured it touse your proxy. Follow the Homebrew proxy configuration instructions.


If you are behind a proxy, HTTP_PROXY and HTTPS_PROXY must be set to connect to Azure services with the CLI.If you are not using basic auth, it's recommended to export these variables in your .bashrc file.Always follow your business' security policies and the requirements of your system administrator.

In order to get the bottle resources from Homebrew, your proxy needs to allow HTTPS connections tothe following addresses:



The CLI is regularly updated with bug fixes, improvements, new features, and preview functionality. A new release is available roughly everythree weeks.

The CLI provides an in-tool command to update to the latest version:


The az upgrade command was added in version 2.11.0 and will not work with versions prior to 2.11.0.

Mac Python3 Update

This command will also update all installed extensions by default. For more az upgrade options, please refer to the command reference page.

You can also update your local Homebrew repository information and then upgrade the azure-cli package.


If you decide to uninstall the Azure CLI, we're sorry to see you go. Before you uninstall, use the az feedback command to let us knowwhat could be improved or fixed. Our goal is to make the Azure CLI bug-free and user-friendly. If you found a bug, we'd appreciate it if you file a GitHub issue.


Use homebrew to uninstall the azure-cli package.

Other installation methods

If you can't use homebrew to install the Azure CLI in your environment, it's possible to use the manual instructions for Linux. Note thatthis process is not officially maintained to be compatible with macOS. Using a package manager such as Homebrew is always recommended. Only use the manualinstallation method if you have no other option available.
