Answer 1

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

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

Answer 2

You could use home-brew

Then just run:

brew install python3

Answer 3

I solved the same problem with these commands:

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

Answer 4

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 <package>.

---

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.

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

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.
