@ShivakrishnaChippa the magic above creates: 1) the /usr/local/Frameworks directory; 2) change ownership of the directory to the current user, and finally 3) brew link creates symlinks to the installs youve done manually on Cellar.

How do I bind Python 2 7 14 14 to prepare for binding?
python now uses python3 (v3.6.5 for now), brew will link the directory: To use homebrews python just put your directory in PATH, for bash: homebrew used to link python to /usr/local/share/python in the older versions. That was the trick for me. By default brew installs python3 in your path, not an exec named python ..
There is an entry /usr/local/bin/python3.6 and there is a symlink /usr/local/bin/python -> python3 but NO /usr/local/bin/python3 entry. so if ln -s /usr/local/bin/python3.6 python3
Unversioned symlinks python, python-config, pipetc. pointing to python3, python3-config, pip3etc., respectively, were installed in /usr/local/opt/python/libexec/bin This means… if you want the python command to start python3 and pipto to start pip3, you need to put /usr/local/opt/python/libexec/bina at the beginning of your PATH.

Make sure you have good test coverage (coverage.py can help; python -m pip install cover) Use Futurize (or Modernize) to update your code (e.g. python -m pip install future) Use Pylint to make sure you dont go back to your Python 3 support ( python -m pip install pylint)
There is an entry /usr/local/bin/python3.6 and there is a symlink /usr/local/bin /python -> python3 but NOT /input usr/local/bin/python3. so if ln -s /usr/local/bin/python3.6 python3
Error: Unable to link file: /usr/local/Cellar/python/2.7.5/bin/smtpd2.py Target /usr/local/bin/ smtpd2 .py already exists. You may need to remove it. To force link and overwrite all other conflicting files, do the following: brew link –overwrite formula_name To list all files that would be deleted: brew link –overwrite –dry-run formula_name
This also saves you from having to to run Modernize or futurize your code regularly to detect compatibility regressions. This requires it to only support Python 2.7 and Python 3.4 or newer, as this is the minimum support for the Pylint version of Python.
What exactly does brew link do?
means of selling and delivering applications to end users. On the phone itself, BREW is a thin client (about 150,000) that sits between a software application and application-specific integrated circuit (ASIC) level software. Therefore, developers can write to BREW without knowing or caring about the devices chipset or air interface.
BREW stands for Binary Runtime Environment for Wireless Networks and is a third-party application development system for mobile phones used by some applications and other programs. If you suddenly started receiving strange, unexplained text messages beginning with the term BREW, its not a beer ad gone bad.
Authentication allows the developer to access the BREW Developer Extranet where it can be viewed and/or downloaded. For example, BREW ClassID Generator guarantees to provide a unique 32-bit identifier for each application.
Backlinks are links from one page of a website to another. If someone links to your site, you have a backlink from them. If you link to another website, they have a backlink from you. For example, these words link to YouTube, so they now link back to us. Marginal note.

How to use python homebrew with Brew?
Homebrew should work with any CPython and default to macOS Python. Homebrew provides formulas to build Python 3.x. Homebrew improves a python@2 formula until the end of 2019 when it was removed due to the deprecation of Python 2.
Elaborate Python Modules. For sophisticated Python, modules installed with pip or python setup.py install will be installed in the $(brew –prefix)/lib/pythonX.Y/site-packages directory (explained above). The python executable scripts are in $(brew –prefix)/bin.
You need to edit your PATH environment variable to make sure the python homebrew is before /usr/bin. You can also configure things in your shell config so that a variable like PYTHON is set to the desired version of python and calls $PYTHON instead of python from the command line.
Now that you have a working compiler , you can proceed to install homebrew . To install Homebrew, you will download an installer script and then run the script. The command uses curl to download the Homebrew installer script from the Homebrew Git repository on GitHub. Lets look at the flags associated with the curl command:
Given how many scripts that call /usr/bin/env python expecting python 2, its probably a bad idea to have python 3. As Benny said in a comment, /usr/bin/env python3 is the good solution.
The remaining packages in Ubuntu that require Python 2.7 are updated to use /usr/bin/python2 as the interpreter, and /usr/bin/python is not present by default on any new install. etc etc Unfortunately, as you have learned, this change to the Ubuntu 20.04LTS distribution may not have been done as well as it could have been. /…/3.6/bin is before the usr/local/bin directory, which means that python3 from /Library/Frameworks/…/3.6/bin.
will be used This is because env looks for python in its PATH , not in a shell, alias, or builtin function. Since you set python as python3 as the alias, env wont find it, it will search the PATH and resolve python to /usr/bin/python (which is python2). You can check all available Python executables, in bash, do:
