There are a couple options when we think about common installation patterns for applications on macOS. Use Python 3 as the macOS default. Python's website has a macOS Python 3 installer we can download and use. If we use the package installation, a python3 fill will be available in /usr/local/bin/. Dec 05, 2017 On OS X, install PortAudio using Homebrew: brew install portaudio. Then, install PyAudio using Pip: pip install pyaudio. On other POSIX-based systems, install the portaudio19-dev and python-all-dev (or python3-all-dev if using Python 3) packages (or their closest equivalents) using a package manager of your choice, and then install PyAudio. Python 3.8.1. Release Date: Dec. This is Python 3.8.1, the first maintenance release of Python 3.8. The Python 3.8 series is the newest major release of the Python programming language, and it contains many new features and optimizations. Major new features of the 3.8 series, compared to 3.7. PEP 572, Assignment expressions.
Apple Mac OS X. Use Homebrew to install the prerequisite portaudio library, then install PyAudio using pip:. Brew install portaudio pip install pyaudio Notes: If not already installed, download Homebrew. Pip will download the PyAudio source and build it for your version of Python. To install PyAutoGUI, install the pyautogui package from PyPI by running pip install pyautogui (on Windows) or pip3 install pyautogui (on macOS and Linux). (On macOS and Linux, pip refers to Python 2’s pip tool.) OS-specific instructions are below. NOTE: As of October 2019, the Pillow module doesn’t support Python 3.8.
PyCharm provides methods for installing, uninstalling, and upgrading Python packages for a particular Python interpreter. By default, PyCharm uses pip to manage project packages. For Conda environments you can use the conda package manager.
To manage Python packages for the project interpreter, select the Project Interpreter page in the project Settings/Preferences or select Interpreter Settings in the Python Interpreter widget.
If you select a Python interpreter with the configured Conda environment, the Use Conda Package Manager toggle appears in the packages area toolbar.
Use this toggle to manage packages from the Conda environment repository. By default, this toggle is switched off and you can manage only the packages available with the selected Python interpreter.
Install a package
- Click Install .
- In the Available Packages dialog that opens, preview the list of the available packages.To specify a custom repository, including devpi or PyPi, click Manage Repositories.
In the Manage Repositories dialog that opens, click to add a URL of a local repository, for example, http://localhost:3141/root/pypi/+simple/, then click OK. In the Available Packages dialog, click to reload the list of the packages. - Type the name of the package to install in the Search field. The list shrinks to show the matching packages only.
- If required, select the following checkboxes:
- Specify version: if this checkbox is selected, you can select the desired version from the list of available versions. By default, the latest version is taken.
- Options: If this checkbox is selected, you can type the
pip install
command-line options in the text field. - Install to user's site packages directory <path>: If this checkbox is left cleared (by default), then the packages will be installed into the current interpreter package directory. If the checkbox is selected, the packages will be installed into the specified directory. This option is not available for Conda environments.
- Select the target package and click Install Package.
Uninstall a package
- In the list of the packages, select the packages to be removed.
- Click Uninstall (). The selected packages are removed from disk.
PyCharm smartly tracks the status of packages and recognizes outdated versions by showing the number of the currently installed package version (column Version), and the latest available version (column Latest version). When a newer version of a package is detected, PyCharm marks it with the arrow sign and suggests to upgrade it.
By default, the Latest version column shows only stable versions of the packages. If you want to extend the scope of the latest available versions to any pre-release versions (such as beta or release candidate), click Show early releases.
Upgrade a package
- In the list of the packages, select the package to be upgraded.
- Click Upgrade ( ). Note that clicking Apply doesn't lead to package upgrading. This button only utilizes all performed package changes.The selected packages are upgraded to the latest available versions.
You can upgrade several packages at once. Hold Cmd (macOS) or Ctrl on (Unix or Windows), left-click to select several items in the list of packages, and then click Upgrade.
If you're accustomed to installing packages from the commands line, you can proceed with your workflow using the Python console.
Reuse installed packages
- Create a new virtual environment and install packages that you want to be used in other projects. Then you can specify this virtual environment as a project interpreter for the target project and all the needed packages will be available.
- In the Terminal window execute the following command:
pip freeze > requirements.txt
Then add the createdrequirements.txt
file to the target project and PyCharm will prompt you to install the packages listed in the file.
Historically MacOS came preinstalled with Python 2, however starting with Mac 10.15 (released in October 2019) this is no longer the case. And since Python 2 will no longer be officially supported as of January 1, 2020, you should really use Python 3 instead.
There are multiple ways to install Python 3 on a MacOS computer. The official Python website even recommends downloading it directly, however this approach can cause confusion around PATH variables, updates, and uninstalls. A better approach, in my opinion, is to instead use the popular package manager Homebrew which automates updates and juggling multiple versions of Python on a computer.
Is Python 3 already installed?
Before we start, make sure Python 3 isn’t already installed on your computer. Open up the command line via the Terminal application which is located at
Applications -> Utilities -> Terminal
.Then type the command
python --version
followed by the Enter key to see the currently installed version of Python.Note: The dollar sign, (
$
), indicates user input. Everything after is intended to be typed by the user followed by the Enter key. Any output, such as Python 2.7.17
in this case, does not have a dollar sign in front.In short: don’t type $
before your commands!It’s possible that Python 3 may have already been installed as
python3
. Run the command python3 --version
to check, however most likely this will throw an error.Install XCode
The first step for Python 3 is to install Apple’s Xcode program which is necessary for iOS development as well as most programming tasks. We will use XCode to install Homebrew.
In your Terminal app, run the following command to install XCode and its command-line tools:
It is a large program so this make take a while to download. Make sure to click through all the confirmation prompts XCode requires.

Install Homebrew
Next install Homebrew by copy/pasting the following command into Terminal and then type Enter:
![Install pyaudio for python 3.7 macos free Install pyaudio for python 3.7 macos free](/uploads/1/2/6/6/126615606/606217799.png)
To confirm Homebrew installed correctly, run this command:
Install Python 3
Now we can install the latest version of Python 3. Type the following command into Terminal and press Enter:
To confirm which version of Python 3 was installed, run the following command in Terminal:
![Install Pyaudio For Python 3.7 Macos Install Pyaudio For Python 3.7 Macos](/uploads/1/2/6/6/126615606/827079313.png)
Finally, to run our new version of Python 3 open an interactive shall by typing
python3
within Terminal:To exit the Python 3 interactive shell, you can type either
exit()
and then Return or type Control+d
which means hold both the Control and D keys at the same time.Note that it is still possible to run Python 2 by simply typing
python
:Virtual Environments
By default, Python packages are installed globally on your computer in a single directory. This can cause major problems when working on multiple Python projects!
For example, imagine you have Project A that relies upon Django 1.11 whereas Project B uses Django 2.2. If you naively installed Django on your computer, only the latest install would be present and available in that single directory. Then consider that most Python projects rely on multiple packages that each have their own version numbers. There’s simply no way to keep everything straight and not inadvertently break things with the wrong package versions.
The solution is to use a virtual environment for each project, an isolated directory, rather than installing Python packages globally.
Confusingly, there are multiple tools for virtual environments in Python:
- venv is available by default on Python 3.3+
- virtualenv must be installed separately but supports Python 2.7+ and Python 3.3+
- Pipenv is a higher-level tool that automatically manages a separate virtual environment for each project
On MacOS we can install Pipenv with Homebrew.
Then use Pipenv for any Python packages you wish to install. For example, if you want to work with Django 2.2.6, first create a dedicated directory for it on your computer such as in a
django
directory on your Desktop.Then install Django within that directory.
If you look within the directory there are now two new files,
Pipfile
and Pipfile.lock
, which Pipenv uses. To activate the virtual environment type pipenv shell
.There will now be parentheses around the name of your current directory which indicates the virtual environment is activate. To exit the virtual environment, type
exit
.The lack of parentheses confirms the virtual environment is no longer active.
