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.
INFO:
OS => MacOS High Sierra 10.13.1
pip3 install twilio -bash: pip3: command not found

Python 3.4+ in most operating systems includes pip3 by default. If your python version is less than 3.4, then you should upgrade your Python version which will automatically install pip3. For example, you can install the latest version of Python from ActiveState (Python 3.9), which includes pip3.
To Solve sudo: pip3: command not found Error Just use python3 -m pip and this solved my problem. Second solution is Just check pip installed or not with this command pip3 -V If pip is not installed then You would need to install pip3. For Linux Users sudo apt install python3-pip.
How could I install pip3 on my Mac? 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 the pip for your python version which runs the script.
Installing pip on OS X After the program runs, use the command pip --version (or pip3 --version ) to make sure pip was installed correctly.
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 python3but that also threw an error directly from Homebrew telling me that it doesn't allow the use ofsudo 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:
