Now that you fixed the permissions, you can go ahead and install a python2 interpreter that will NOT ever require sudo with pip and hence will install your packages just fine: (don't worry we will get to python3 as well) That's why we made everything belong to us Let's install the one and only python2 we will use!: That's why the next step is so important:īasically, everything in this folder is supposed to NOT require root priviliges, which if they do they give pip a hard time later on. Thus any attempt to install new python versions will seem to work fine for now, but will be a brat later on. Then there is a good chance you messed up permissions with some packages too. Here's the fun part: if you already messed up your python environment, What's important is how you install the new version. If you have anaconda installed, get rid of that too:.In other words, delete old paths related to python. bash_profile):ĭelete all lines that have amework in it. zprofile or whichever shell you are using (If you don't know what I'm talking about then it's. (source: but I changed it a bit to remove python3 too)Įdit whatever shell profile you have, like. ![]() Ls -l /usr/local/bin | grep './Library/Frameworks/amework/Versions/2.7' | awk '' | tr -d | xargs rm Otherwise you WILL have to reinstall macos, it WILL crash, don't do it. Remove all the third party python installations:Ĭareful! Don't delete anything under the /System/ folder.I am not sure if this is really necessary, but I did it just so I get a fresh start First, remove all the python packages you installed.any attempt to fix using online resources made it worse.almost no package I installed with pip worked without a headache.Too many different symlinks which I lost track of.I had too many different python interpreters.Here is what I had messed up, which you also probably did: Whatever I install for python2 or python3 using pip JUST.WORKS. Today, I finally fixed my python installation. RabbitMQ – How to do a Rolling upgrade in a Cluster (Version 3.I am assuming you are here because like me, you installed a bazillion different python interpreters on mac and the whole thing is a spagetti.RabbitMQ – How to join a node to a cluster when you get the error: incompatible_feature_flags May 14, 2021.Redis – How to Setup a Six Node Redis Test Cluster in Ubuntu on Windows 10 October 26, 2021.OpsCenter – Setting up Authentication with Roles and Users March 1, 2022.RabbitMQ – How to Install RabbitMQ on Windows 10 October 21, 2022.Now you will have Python 2.7 on your Mac, with easy_install, pip, and virtualenv ready to go. Now that we have pip, lets install a very important package called virtualenv! Now we can install any python packages we want using pip! Install Virtualenv (Using pip) You will need a new terminal session for easy_install to show up on the path. To install setup tools just run the egg file like any other shell script: Install Setup Tools (this includes easy_install)ĭownload the egg file for your version of python (for this example, 2.7) from the Setup Tools Downloads page. Ln -s /Library/Frameworks/amework/Versions/Current/bin/python python #Switch the /usr/bin/python link to point to current python link #Create a soft link in /Library/Frameworks/amework/Versions/Ĭd /Library/Frameworks/amework/Versions/ So the next time we upgrade, we will only need to change the “Current” version link. Let’s switch the /usr/bin/python link to point to the newest version of Python, and at the same time let’s create a soft link in the Python install folder that always points to the current install of Python. NOTE: Even though we have installed python 2.7, your /usr/bin/python is still pointing to an older version of Python, so for example if you run easy_install, if will run from the older version of Python, and install packages into the library of the old Python installation. Library/Frameworks/amework/Versions/2.7/bin/python You should now have Python 2.7 installed in:.Just open the dmg and follow the installer as you would with any application So here is a simple set of instructions that seem to work for me!
