So the Python (provided by OSX system)is indeed in System/Library/Frameworks/amework/Versions/2.7/lib/python2.7. Take Python2.7 for example, the Python2.7 in /usr/lib/ points to What is more, the Python2.5 Python2.6 and Python2.7 files here are all substitutes.

So I cd into /usr/lib/ and find Python2.5 Python2.6 and Python2.7 here. User_paths = os.environ.split(os.pathsep)ДЇrom the above passage, we can see that one version of python is located in /usr/local/lib/python2.7, and I guess that the OSX systemвЂ™s Python is probably in usr/lib/. We can also figure out pythonвЂ™s path in the python IDLE by the following code. Which shows the path of the python unix execute file Library/Frameworks/amework/Versions/2.7/bin/python We can get that the python path is /usr/local/lib/python2.7/site-packages PATH='/Library/Frameworks/amework/Versions/2.7/bin:$' There are 3 ways to find your pythonвЂ™s path:ДЄnd you can see something similar as the following lines 1Д®xport PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH PYTHONPATH is an environment variable, much like PATH and it tells the terminal that which Python it should run when you type вЂpythonвЂ™ in terminal. The result is that I am always confused by my multiply python versions, especially when I want to link them with my IDE or add some useful site-packages. system level modules.There are at lease 3 versions of Python in my computer, the defaule python2.7 provided by OSX is the first one, and the python2.7 and python3.3 installed by homebrew are another two versions. Additionally, itвЂ™s generally not recommended to mess with the System (Apple-provided) Python, because it tends to make permissions complicated when installing user vs. ItвЂ™s helpful to use the absolute path for pip to help alleviate that confusion.

You can delete the entire venv and reinstall all your dependencies if there were any incorrect versions.ДЇrom Nick: On macOS, especially if you install python from different/multiple sources (such as brew,, etc), `pip` on the command line may not actually point to the Python you expect, based on order in the path. In almost all cases itвЂ™s better to spin up an independent Python environment (a virtual environment) to install packages into that can be considered disposable. `pip` doesnвЂ™t handle dependency trees, so you need to be careful that youвЂ™re cleaning up additional packages. When you go to re-install requests at the older version, the newer version of urllib3 that you had installed likely still meets the version required by requests. If you meant to install an older version of requests, and uninstalled it, youвЂ™re only removing that package and none of the sub-requirements that came along with it. The above will produce verbose logs so that if itвЂ™s failing because of a weird reason you can case that down.ДЇrom Bryson: If you do a вЂњ`pip uninstall $вЂњ` you may (usually will) end up with a lot of other packages that arenвЂ™t at the desired version.Д®xample: `requests` has its own requirements including `urllib3`. You can then install verbosely, using the URI of the project. If you end up with a bad install or one that isnвЂ™t working properly, you can always uninstall the module.

Now that I have a requirements file, I can use that to install packages on the next host I run the script on:Д«ut what if I need to make sure that I donвЂ™t update beyond those versions. This would usually follow the below syntax: A practice I try to follow is to take the version of a module I was using when I wrote a script and create a requirements.txt file alongside it.Д«asically, if I import then IвЂ™ll add what I imported into the requirements.txt file. Python3 comes with a hand-dandy little tool called pip3 for installing modules you import in scripts. Python comes with a handy-dandy little tool called pip for installing modules that you import in scripts.
