Tl;dr TIL pygame is broken using homebrew Python3, so I decided to wipe my shit and start from scratch. I figured I'd give you the quickness on what I did so next time this shit happens to someone, they have a handy reference. Wartune farm bot. Brew versions is not longer supported. Brew search python3 does not show python3.X versions. Brew tap homebrew/versions does not work neither. How can I install python3.3 in macosx using brew and I don't want to use pyenv. Python has been installed as $(brew -prefix)/opt/python@3.7/bin/python3 Unversioned symlinks `python`, `python-config`, `pip` etc.
Manage different versions of homebrew packages
Project description
Manage multiple versions of your Homebrew packages with ease!Homebrew makes this difficult as a design decision, but sometimes old packagesneed to be installed and we need a way to do so easily.
Installation
With pipx
Or just with pip:
Usage
Switch to a specific version:
Installing from taps:
When no bottle is found for taps it will proceed with searching thelocal tap repository for the correct version and installing from the bottledefined in the formula if it exists, otherwise from source.
This is very slow for the main homebrew repository so this behaviour is disabledwhen a bottle for a homebrew-core package cannot be found. You can supplythe option brewv switch --slow .. to perform this search.
Warnings
Proper SHA256 verification is not done when downloading bottles from themain bottle repository. This is because to get the expected SHAs would mean searchingthe huge homebrew-core repository.
While homebrew bottles exist for most operatingsystems, if the bottle is not found then parsing old formulas fails quite oftensince Homebrew updates their code frequently.

Question or issue on macOS:
How can I install a previous version of Python 3 in macOS using brew?
With the command brew install python I got the latest version of Python 3 (currently v3.7.0), but I want the last version of Python 3.6 (currently 3.6.5).
I have read about another package pyenv that can assist in handle different python installation, but this solution is not suitable for me.
How to solve this problem?
Solution no. 1:
Short Answer
To make a clean install of Python 3.6.5 use:
If you prefer to recover a previously installed version, then:
Long Answer
There are two formulas for installing Python with Homebrew: [email protected] and python.
The first is for Python 2 and the second for Python 3.
Note: You can find outdated answers on the web where it is mentioned python3 as the formula name for installing Python version 3. Now it’s just python!
By default, with these formulas you can install the latest version of the corresponding major version of Python. So, you cannot directly install a minor version like 3.6.
Pricing details. Azure Active Directory comes in four editions—Free, Office 365 apps, Premium P1, and Premium P2. The Free edition is included with a subscription of a commercial online service, e.g. Azure, Dynamics 365, Intune, and Power Platform. Office 365 active directory login. Microsoft 365 uses an Azure Active Directory (Azure AD) tenant to store and manage identities for authentication and permissions to access cloud-based resources. If you have an on-premises Active Directory Domain Services (AD DS) domain or forest, you can synchronize your AD DS user accounts, groups, and contacts with the Azure AD tenant of. This article applies to both Microsoft 365 Enterprise and Office 365 Enterprise. Microsoft 365 uses Azure Active Directory (Azure AD), a cloud-based user identity and authentication service that is included with your Microsoft 365 subscription, to manage identities and authentication for Microsoft 365.
Solution
With brew, you can install a package using the address of the formula, for example in a git repository.
Or specifically for Python 3
The address you must specify is the address to the last commit of the formula (python.rb) for the desired version.
You can find the commint identifier by looking at the history for homebrew-core/Formula/python.rb
Python > 3.6.5
In the link above you will not find a formula for a version of Python above 3.6.5.
After the maintainers of that (official) repository released Python 3.7, they only submit updates to the recipe of Python 3.7.
As explained above, with homebrew you have only Python 2 ([email protected]) and Python 3 (python), there is no explicit formula for Python 3.6.
Although those minor updates are mostly irrelevant in most cases and for most users, I will search if someone has done an explicit formula for 3.6.
Solution no. 2:
As an update, when doing
You may encounter
To bypass it, add the --ignore-dependencies argument to brew install.
Solution no. 3:
What I did was first I installed python 3.7
then I installed python 3.6.5 using above link
After that I ran brew link --overwrite python. Now I have all pythons in the system to create the virtual environments.
To create Python 3.7 virtual environment.
To create Python 3.6 virtual environment
Solution no. 4:
I have tried everything but could not make it work. Finally I have used pyenv and it worked directly like a charm.
So having homebrew installed, juste do:
to manage virtualenvs:
See pyenv and pyenv-virtualenv for more info.
EDIT (2019/03/19)
I have found using the pyenv-installer easier than homebrew to install pyenv and pyenv-virtualenv direclty:
To manage python version, either globally:
or locally in a given directory:
Solution no. 5:
I tried all the answers above to install Python 3.4.4. The installation of python worked, but PIP would not be installed and nothing I could do to make it work. I was using Mac OSX Mojave, which cause some issues with zlib, openssl.
What not to do:
- Try to avoid using Homebrew for previous version given by the formula Python or Python3.
- Do not try to compile Python
Solution:
- Download the macOS 64-bit installer or macOS 64-bit/32-bit installer: https://www.python.org/downloads/release/python-365/
- In previous step, it will download Python 3.6.5, if for example, you want to download Python 3.4.4, replace in the url above python-365 by python-344
- Download click on the file you downloaded a GUI installer will open
- If you downloaded python-365, after installation, to launch this version of python, you will type in your terminal python365, same thing for pip, it will be pip365
p.s: You don’t have to uninstall your other version of Python on your system.
Edit:
I found a much much much better solution that work on MacOSX, Windows, Linux, etc.
- It doesn’t matter if you have already python installed or not.
- Download Anaconda
- Once installed, in terminal type:
conda init - In terminal,create virtual environment with any python version, for example, I picked 3.4.4:
conda create -n [NameOfYour VirtualEnvironment] python=3.4.4 - Then, in terminal, you can check all the virtual environment you ahave created with the command:
conda info --envs - Then, in terminal, activate the virtual environment of your choice with:
conda activate [The name of your virtual environment that was shown with the command at step 5]
Solution no. 6:
In case anyone face pip issue like below
The root cause is openssl 1.1 doesn’t support python 3.6 anymore. So you need to install old version openssl 1.0
here is the solution:
Solution no. 7:
To solve this with homebrew, you can temporarily backdate homebrew-core and set the HOMEBREW_NO_AUTO_UPDATE variable to hold it in place:
I don’t recommend permanently backdating homebrew-core, as you will miss out on security patches, but it is useful for testing purposes.
You can also extract old versions of homebrew formulae into your own tap (tap_owner/tap_name) using the brew extract command:
Solution no. 8:
The easiest way for me was to install Anaconda: https://docs.anaconda.com/anaconda/install/
Brew Install Python 3.8
There I can create as many environments with different Python versions as I want and switch between them with a mouse click. It could not be easier.
To install different Python versions just follow these instructions https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-python.html
A new development environment with a different Python version was done within 2 minutes. And in the future I can easily switch back and forth.
Brew Update Python3
Hope this helps!
