I'm trying to install pip3, but I'm not having any luck. Also, I tried sudo install and it did not work. How could I install pip3 on my Mac?

sudo easy_install pip3

UPDATED - Homebrew version after 1.5

According to the official Homebrew page:

On 1st March 2018 the python formula will be upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7 (although this will be keg-only so neither python nor python2 will be added to the PATH by default without a manual brew link --force). We will maintain python2, python3 and python@3 aliases.

So to install Python 3, run the following command:

brew install python3

Then, the pip or pip3 is installed automatically, and you can install any package by pip install .

The older version of Homebrew

Not only brew install python3 but also brew postinstall python3

So you must run:

brew install python3
brew postinstall python3

Note that you should check the console, as it might get you errors and in that case, the pip3 is not installed.

For me brew postinstall python3 didn't work. I found this solution on the GitHub Homebrew issues page:

$ brew rm python
$ rm -rf /usr/local/opt/python
$ brew cleanup
$ brew install python3

I ran the below where : matched the other : for other files in the /usr/local/lib/python3.7/site-packages/ directory:

sudo chown -R : /usr/local/lib/python3.7/site-packages/pip*
brew postinstall python3

I solved the same problem with these commands:

curl -O https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

If you're using Python 3, just execute python3 get-pip.py . It is just a simple command.

To install or upgrade pip, download get-pip.py from the official site. Then run the following command:

sudo python get-pip.py 

and it will install pip for your python version which runs the script.

You could use Homebrew.

Then just run:

brew install python3

Similar to Oksana but add python3

$ brew rm python 
$ brew rm python3 
$ rm -rf /usr/local/opt/python
$ rm -rf /usr/local/opt/python3
$ brew prune 
$ brew install python3
$ brew postinstall python3

Seem now work for pip3 under mac os x 10.13.3 Xcode 9.2

Python 3 was working successfully, but without pip3. I tried advice from Stack Overflow, Quora and others (numerous installs and uninstalls).

Python 3 was always fine, but without pip3. Finally I downloaded Python3 from: https://www.python.org/downloads/

By simple mouse clicks and everything (Python 3 + pip3), it is working fine now.

After upgrading to macOS v10.15 (Catalina), and upgrading all my vEnv modules, pip3 stopped working (gave error: "TypeError: 'module' object is not callable").

I found question 58386953 which led to here and solution.

  1. Exit from the vEnv (I started a fresh shell)
  2. sudo python3 -m pip uninstall pip (this is necessary, but it did not fix problem, because it removed the base Python pip, but it didn't touch my vEnv pip)
  3. sudo easy_install pip (reinstalling pip in base Python, not in vEnv)
  4. cd to your vEnv/bin and type "source activate" to get into vEnv
  5. rm pip pip3 pip3.6 (it seems to be the only way to get rid of the bogus pip's in vEnv)
  6. Now pip is gone from vEnv, and we can use the one in the base Python (I wasn't able to successfully install pip into vEnv after deleting)

I also encountered the same problem but brew install python3 does not work properly to install pip3.

brre will throw the warning The post-install step did not complete successfully.

It has to do with homebrew does not have permission to /usr/local

Create the directory if not exist

sudo mkdir lib 
sudo mkdir Frameworks

Give the permissions inside /usr/local to homebrew so it can access them:

sudo chown -R $(whoami) $(brew --prefix)/*

Now ostinstall python3

brew postinstall python3

This will give you a successful installation
