Install Pip For Mac Via Homebrew
First of all, you’ll need to have this thing called HomeBrew installed on your Mac. Homebrew is basically a “package manager”. A package manager is an application that helps you install the stuff you need that Apple (or even your Linux System) hadn’t installed in the first place for you.
In this tutorial we will learn to install NodeJS and NPM on Mac using Homebrew.
Step 1: Install Homebrew
Homebrew is 'The missing package manager for macOS'.
Open terminal and type the following command.
This will install Homebrew on your Mac. To check the version type the following command.
Output
Why use Homebrew to install NodeJS?
If you are installing NodeJS via the installer from https://nodejs.org/ then you have to use sudo to make sure that it installs correctly. After that you have to make changes in your system $PATH by adding the path of the node executable. And if you want to uninstall node then you have track all the files that were created and get rid of them. In short its a long process.
That's why Homebrew is used. It makes the job easy. It will install/uninstall Node easily.
Step 2: Install Node via Homebrew
In the terminal type the following command to install Node.
If everything installed successfully then you can type in the following command in the terminal to check the Node and NPM version.
Possible issues/errors that may occur
If you look above you will see that we have some issues.
So, in terminal type the following command.
We also got an error 'Error: The `brew link` step did not complete successfully'.
So, type the following command.
Output
The above output says:
You may want to remove it:
rm '/usr/local/share/man/man1/node.1'
So, use the following command.
Now, to list all files that would be deleted use the following command.
Output
Now we got the Error: Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.
To fix this we have to change the username and group of the systemtap directory.
Type the following command in the terminal.
Output
Now, run the --overwrite --dry-run command again.
Output
Now, we got the Error: Could not symlink lib/dtrace/node.d
/usr/local/lib/dtrace is not writable.
To fix this we have to change the username and group of the dtrace directory.
In the terminal type in the following command.
Output
Now, run the --overwrite --dry-run command again. Hopefully you will get no error. So, its time to run the --overwrite command.
Output
Congratulation! You have successfully installed NodeJS and NPM on your Mac via Homebrew.
Just like any serious programming language, Python supports third-party libraries and frameworks that you can install to avoid reinventing the wheel with every new project. If you want to use them you can find these Python libraries on a central repository called the Python Package Index (PyPI).
Downloading, installing, and managing these packages by hand can be frustrating and time-consuming. This is why many Python developers rely on a special tool called PIP for Python (or Python PIP) to make everything much easier and faster.
What Is PIP for Python?
PIP is an acronym that stands for “PIP Installs Packages” or “Preferred Installer Program”. It’s a command-line utility that allows you to install, reinstall, or uninstall PyPI packages with a simple and straightforward command: pip.
If you’ve ever done any command-line work on Windows (with the Command Prompt The Quickest Way to Install Windows Software: The Command PromptInstalling apps on Windows takes up a lot of time. Install and update your apps through the command prompt with this method.

Try these tips for mastering the command line. Read More ), then you can skip down to the installation instructions for your particular operating system.
Is PIP Installed With Python?
If you’re using Python 2.7.9 (or greater) or Python 3.4 (or greater), then PIP comes installed with Python by default. If you’re using an older version of Python, you’ll need to use the installation steps below. Otherwise, skip to the bottom to learn how to start using PIP.
If you’re running Python in a virtual environment created with either virtualenv or pyvenv, then PIP will be available regardless of the Python version.
Is Python Correctly Installed?
You have to make sure Python is properly installed on your system. On Windows, open up the Command Prompt using Windows key + X and selecting Command Prompt. On Mac, open the Terminal using Command + Space and searching for terminal. On Linux, open the Terminal using Ctrl + Alt + T. Linux shortcuts may vary by distribution.

Then type:
On Linux, Python 3.x users may need to use:
If you get a version number (e.g. “Python 2.7.5”) then Python is ready to go.
If you get a “Python is not defined” message, then you’ll have to first install Python properly. That’s beyond the scope of this article. The Python site has some detailed instructions for installation.
How to Install PIP on Windows
These instructions should work on Windows 7, Windows 8.1, and Windows 10:
- Download the get-pip.py installer script. If you’re on Python 3.2, you’ll need this version of get-pip.py instead. Either way, right-click on the link and select Save As… and save it to any safe location, such as your Downloads folder.
- Open the Command Prompt and navigate to the get-pip.py file.
- Run the following command: python get-pip.py
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.
If you want to use the native system Python installation but don’t have PIP available, you can install PIP with the following command in Terminal:
If you’d rather install a more up-to-date version of Python, then you can use Homebrew. Don’t know what that is? Learn more about installing software with Homebrew on Mac How to Install Mac Apps in Terminal Using HomebrewDid you know you can install Mac software in the Terminal? Here's how to use Homebrew to install Mac apps easily. Read More . These instructions will assume you already have Homebrew installed and ready to go.
Installing Python with Homebrew is done with a single command:
This will install the latest version of Python, which should come packaged with PIP. If the installation is successful but PIP is unavailable, you may need to re-link Python using the following Terminal command:
How to Install PIP on Linux
If your Linux distribution came with Python already installed, you should be able to install PIP using your system’s package manager. This is preferable since system-installed versions of Python do not play nicely with the get-pip.py script used on Windows and Mac.

How to Install PIP on Raspberry Pi
As a Raspberry Pi user, you’re probably running Raspbian since it’s the official operating system designated and provided by the Raspberry Pi Foundation. You’re free to install another operating system, such as Ubuntu How to Get Ubuntu Running on Your Raspberry PiRaspbian Jessie is a great Raspberry Pi operating system. But what if you want a more traditional Linux experience? Well, you could go ahead and install Ubuntu instead. Read More . If that is the case you should look at the Linux instructions.
Starting with Raspbian Jessie, PIP comes installed by default. It’s one of the big reasons to upgrade to Raspbian Jessie instead of sticking with Raspbian Wheezy or Raspbian Jessie Lite. However, if you’re on an older version of Raspbian, you can still install PIP.
On Python 2.x:
On Python 3.x:
With Raspbian, Python 2.x users should use pip while Python 3.x users should use pip3 when issuing PIP commands.
How to Upgrade PIP for Python
While PIP itself doesn’t update very often, it’s still important to stay on top of new versions because there may be important fixes to bugs, compatibility, and security holes. Fortunately, upgrading PIP is quick and easy.
On Windows:
On Mac, Linux, or Raspberry Pi:
On certain versions of Linux and Raspberry Pi, you may need to use pip3 instead.
How to Manage Python Packages With PIP
Once PIP is ready, you can start installing packages from PyPI:
To install a specific version of a package instead of the latest version:
To search PyPI for a particular package:
To see details about an installed package:
To list all installed packages:
To list all outdated packages: Trend micro unable to start protection mac catalina.
To upgrade an outdated package:
Note that older versions of a package are automatically removed by PIP when upgrading to a newer version of that package.
To completely reinstall a package:
To completely get rid of a package:
