brew install python3 didn't install pip3
Question:
I installed python3 using homebrew but it didn’t install pip3 or should I say it installed but it doesn’t recognize the command ?
Here is what I did:
brew install python3
This installed python3 but threw an error at the end saying it couldn’t link python3 and prompted me to run
brew link python3
to link the installation but this throws another error:
Linking /usr/local/Cellar/python3/3.6.3... Error: Permission denied @ dir_s_mkdir - /usr/local/lib
Does anyone know how solve this ?
When I run:
brew info python3
It says:
==> Caveats
Pip, setuptools, and wheel have been installed. To update them
pip3 install --upgrade pip setuptools wheel
You can install Python packages with
pip3 install <package>
They will install into the site-package directory
/usr/local/lib/python3.6/site-packages
See: https://docs.brew.sh/Homebrew-and-Python.html
Which makes me think pip3 is installed but not recognized. Any help is appreciated.

Ok it took me a lot of googling but the problem is that in high sierra all permissions inside usr/local changed and homebrew has to create some folder inside usr/local. Here is how I solved everything:
I tried using sudo brew install python3
but that also threw an error
directly from Homebrew telling me that it doesn’t allow the use of
sudo brew
.
Create the folders I needed using sudo mkdir inside /usr/local:
sudo mkdir lib
sudo mkdir Frameworks
Change the permissions inside /usr/local so that homebrew can access them:
sudo chown -R $(whoami) $(brew --prefix)/*
Now install python3
brew install python3
This will give you a successful installation:

GitHub user @aether2501, commenting on a sudo chown solution for a “Homebrew Permission Denied” problem, suggests instead that Homebrew be uninstalled/reinstalled after the upgrade to High Sierra.
I successfully used @aether2501’s reinstall command, /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
, on High Sierra (10.13.2) without uninstalling brew first.
In addition to creating the /usr/local/Frameworks directory and setting the necessary ownership and permissions I needed to link python3, it also appears to have fixed other directory issues.
I had the same issue and used:
sudo -H pip3 install virtualenv
sudo -H pip3 install virtualenvwrapper --ignore-installed six
After resolving the linking issue (e.g. https://github.com/Homebrew/homebrew-core/issues/19286 ), python3 is installed but not pip3. Reinstalling python (e.g. brew reinstall python) eventually installs pip3 as well. These steps works well for me.
In my case, this fixed the issue:
brew unlink [email protected]; brew link [email protected]
(You might have to replace the version number with the version you have installed)
I wanted to add my own solution to this exact problem.
On MacOS [specifically Ventura] I did brew install python
– it turns out homebrew does actually install pip
, but the difference is that the actual command to use is now pip3
instead of "pip".
As a result, I aliased the command pip
to equal pip3
by adding this line to my .zshrc
(though if you are working with a bash shell, it’ll work as well):
alias pip="pip3"
When the time comes that pip moves to a ver.4, I’ll have to update this, but for now, it has solved my issue without any further linking or PATH changes.
