Apple’s Mac OS comes with python 2.7 installed by default. Perhaps you may want to use python 3.x.x on your machine and also use pip for package management with
python 3.x.x. The easiest way to achieve this is by:
NOTE: This tutorial does not useVirtual Environments like
pyenv to manage various
python3on your computer.
This will print out the version of python installed on your system. The output should be similar to:
You may verify the installation directory of
python by runningthe following line on the
The main advantage of that solution is that it install pip for the python version that has been used to run get-pip.py, which means that if you use the default OS X installation of python to run get-pip.py you will install pip for the python install from the system. Apr 22, 2020 Mac OS X latest version with Python version 3, then pip is already installed. If you are using Python 2.x or Python 3.x downloaded from python.org or working in the Virtual Environment created by virtualenv or pyvenv. I am a new Mac user, and I need help trying to install pip in OS X El Capitan. I ran this command, python get-pip.py and ended up with this error: Exception: Traceback (most recent call last). Double-click the downloaded file and click continue to start the installation. Answer the prompts on the Introduction, Read Me, and License screens. Click the Install button to install Anaconda in your /opt directory (recommended): OR, click the Change Install Location button to install in another location (not recommended).
The prompt should print the install path for
python3. An example output is:

How to Install PIP on Mac. Modern Mac systems come with Python and PIP already installed. However, this version of Python tends to be outdated and not the best choice for serious Python development. It's highly recommended that you install a more current version of Python and PIP. Get-pip.py can also be used to install a specified combination of pip, setuptools, and wheel using the same requirements syntax as pip: Unix/macOS python get-pip.py pip 9.0.2 wheel 0.30.0 setuptools 28.8.0. The problem with the pip installing gdal is that it only gets the bindings, not the entire library, so it can get tricky. One way to solve it is to use the pip command to download - but not install. Then you tweak the header location from the config file. Then you pip install that. Installing Python 3 on Mac OS X¶ Mac OS X comes with Python 2.7 out of the box. If the Homebrew version of Python 3 is installed then pip will point to Python 3. Now in the year of 2020. Fix this issue by my side with mac: pip install jupyterlab instead pip install jupyter. There will be an warning before successfully installed keywords: enter image description here. You can see the path with jupyterlab then you just need to start jupyter notebook by following in path: jupyter-lab.
This lesson shows you how to download and install Python modules. Thereare many ways to install external modules, but for the purposes of thislesson, we’re going to use a program called pip, easily installable on mac/linux and windows. As of Python 2.7.9 and newer, pip is installed by default. This tutorial will be helpful for anyone using older versions of Python (which are still quite common).
One of the great things about using Python is the number of fantasticcode libraries that are widely and easily available that can save you alot of coding, or simply make a particular task (like creating a CSVfile, or scraping a webpage) much easier. When Googling for solutions toproblems, you’ll often find sample code that uses code libraries youhaven’t heard about before. Don’t let these scare you away! Once theselibraries are installed on your computer, you can use them by importingthem at the beginning of your code; you can import as many libraries asyou’d like, such as
For new Python users, it can be a bit intimidating to download andinstall external modules for the first time. There are many ways ofdoing it (thus adding to the confusion); this lesson introduces one ofthe easiest and most common ways of installing python modules.
The goal here is to install software on your computer that canautomatically download and install Python modules for us. We’re going touse a program called pip.
Note: As of Python 3.4, pip will be included in the regular install.There are many reasons why you might not have this version yet, and incase you don’t, these instructions should help.
As per the pip documentation, we can download a python script to installpip for us. Using a Mac or Linux, we can install pip via the commandline by using the curl command, which downloads the pip installationperl script.
once you’ve downloaded the get-pip.py file, you need to execute it withthe python interpreter. However, if you try to execute the script withpython like
the script will most likely fail because it won’t have permissions toupdate certain directories on your filesystem that are by default set sothat random scripts cannot change important files and give you viruses.In this case—and in all cases where you need to allow a script that youtrust to write to your system folders—you can use the sudo command(short for “Super User DO”) in front of the python command, like
As with the above platforms, the easiest way to install pip is throughthe use of a python program called get-pip.py, which you can downloadhere. When you open this link, you might be scared of the massivejumble of code that awaits you. Please don’t be. Simply use your browserto save this page under its default name, which is get-pip.py. It mightbe a good idea to save this file in your python directory, so you knowwhere to find it.
Once you have saved this file, you need to run it, which can be done intwo ways. If you prefer using your python interpreter, just right-clickon the file get-pip.py and choose “open with” and then choose whateverpython interpreter you care to use.
If you prefer to install pip using the windows command line, navigate towhatever directory you’ve placed python and get-pip.py. For thisexample, we’ll assume this directory is python27, so we’ll use thecommand C:>cd python27. Once you are in this directory, to install pip run thecommand
If you want more information or help with a weird error message, check out the StackOverflowpage that seems to be regularly updated.
Now that you have pip, it is easy to install python modules since itdoes all the work for you. When you find a module that you want to use,usually the documentation or installation instructions will include thenecessary pip command, such as
Remember, for the same reasons explained above (on Mac or Linux systems, but not Windows), you might need to run pip with sudo, like
Sometimes, especially on Windows, you may find it helpful to use the -m flag (to help python find the pip module), like
pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4downloaded from python.org or if you are workingin a Virtual Environmentcreated by virtualenv or venv. Just make sureto upgrade pip.
Use the following command to check whether pip is installed:
If you installed Python from a package manager on Linux, you should alwaysinstall pip for that Python installation using the same source.
See pypug:Installing pip/setuptools/wheel with Linux Package Managersin the Python Packaging User Guide.
Here are ways to contact a few Linux package maintainers if you run intoproblems:
Debian Python Team (for generalissues related to
pip developers do not have control over how Linux distributions handle pipinstallations, and are unable to provide solutions to related issues ingeneral.
Python >=3.4 can self-bootstrap pip with the built-inensurepip module. Refer to the standard librarydocumentation for more details. Make sure to upgrade pipafter
ensurepip installs pip.
See the Using Linux Package Managers section if your Python reports
Nomodulenamedensurepip on Debian and derived systems (e.g. Ubuntu).
Be cautious if you are using a Python install that is managed by your operatingsystem or another package manager.
get-pip.py does not coordinate withthose tools, and may leave your system in an inconsistent state.
To manually install pip, securely 1 download
get-pip.py by followingthis link: get-pip.py. Alternatively, use
Then run the following command in the folder where youhave downloaded
get-pip.py also installs setuptools2 and wheelif they are not already. setuptools is required to installsource distributions. Both arerequired in order to build a Wheel Cache (which improves installationspeed), although neither are required to install pre-built wheels.
The get-pip.py script is supported on the same python version as pip.For the now unsupported Python 2.6, alternate script is availablehere.
If set, do not attempt to install setuptools
If set, do not attempt to install wheel
get-pip.py allows pip install options and the general options. Below aresome examples:
Install from local copies of pip and setuptools:
Install to the user site 3:
Install behind a proxy:
get-pip.py can also be used to install a specified combination of
wheel using the same requirements syntax as pip:
pip works with CPython versions 3.6, 3.7, 3.8 and also PyPy.
This means pip works on the latest patch version of each of these minorversions. Previous patch versions are supported on a best effort approach.
pip works on Unix/Linux, macOS, and Windows.
“Secure” in this context means using a modern browser or atool like
curl that verifies SSL certificates when downloading fromhttps URLs.
Beginning with pip v1.5.1,
get-pip.py stopped requiring setuptools tobe installed first.
The pip developers are considering making
--user the default for allinstalls, including
get-pip.py installs of pip, but at this time,
--user installs for pip itself, should not be considered to be fullytested or endorsed. For discussion, see Issue 1668.
