Reinstalling numpy on OS X using pip - "can’t be modified or deleted because it’s required by OS X"

I'm trying to upgrade the numpy library on macOS, but pip doesn't seem to have sufficient permissions to delete numpy. Running `pip install --upgrade pip gives me this traceback:
➜ Desktop sudo -H pip install --upgrade numpy

So apparently pip is having trouble deleting /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info. Trying to delete this file manually in finder gives me this error:
“numpy-1.8.0rc1-py2.7.egg-info” can’t be modified or deleted because it’s required by OS X.
How can I solve this? (Using the builtin numpy isn't an option because tensorflow, a package I need, needs the newest version).

Was facing the same issue
sudo pip install --ignore-installed numpy

For me on macOS High Sierra the below worked well:
sudo pip install --ignore-installed numpy

Install tweepy module with pip

I'm relatively new to coding but feel like I have a firm understanding of the basics. I am looking to use python to experiment with twitter using the tweepy module but I'm having trouble install it, and other modules too, using pip in the command line.
Typing pip pip install tweepy into the command line (Terminal on macOS Sierra) returns the string of errors at the end of this post.
If anyone could shed any light onto why I can't install any modules I would very much appreciate it.
Thanks in advance.

As mentioned above, you need root access where pip stores the packages.
Python 3.x:
sudo pip3 install tweepy
Python 2.x:
sudo pip install tweepy
You may also use Git to clone the repository from Github and install it manually:
git clone https://github.com/tweepy/tweepy.git
cd tweepy
python setup.py install
Alternatively you can use virtualenv
"What if you can't install packages into the global site-packages directory? For instance, on a shared host.
In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn't share libraries with other virtualenv environments (and optionally doesn't access the globally installed libraries either)."
Basically it's allow you to create an isolated environment for each of your project and it's help on permission issue you have.
For more information:
Installing Python on Mac OS X: virtualenv

Operation not permitted
You need to run:
sudo pip install tweepy

You have problems with permissions. As suggested above, you can try to use sudo

Python: permission denied error when installing pip

I am a student and I am doing project on department computer, system Linux 7.2. Now I am trying to install pip so that I can install python packages using it.
I have downloaded get-pip.py and tried to install via python get-pip.py. It gives me:

Then, I tried to install using sudo python get-pip.py, however, I got "xxx is not in the sudoers file. This incident will be reported."
So, I was wondering whether I don't have the permission to root and don't have the right to do sudo...but I am not sure about this...
Any suggestion to fix this problem? And in the end, I want to install scipy and gensim.

Does the system hand you a virtualenv command?
Then you should read about virtualenvs. Comes in handy anyhow.
If not you may use the approach by Jasper van den Bosch

You either need to use a virtual environement, and install the pip package in the virtual env. Or install it with pip globally ie system wide as root user

Try install pip using easy_install
Try Below commands in terminal:
sudo su
easy_install pip

Using PIP to download a Python Package. Permission error

I'm using PIP to get a package I need for Python but I'm getting a permission error even when I'm using "sudo" to access the package.
I'm following the instructions posted here on the website for the package.
sudo pip install -U nltk

It says my parent directory is not owned by me ... but I'm the only user on my computer. So I don't know what is going on here.
Thanks,

Got very similar issue while trying to install awscli. Following worked for me. Just changing the package name. You can try -
sudo -H pip install nltk --upgrade --ignore-installed six

Does anyone have a fix? Installing this has been a real headache. Thanks a lot!

A quick workaround would be to use the sudo pip install praw command to intall praw as a super-user. However, this is not recommended, as it can cause problems later on with things such as updates and scaling your application upwards. One would instead suggest that you create a virtual environment, and pip install praw inside it.
If you are confident that the application you are building will not grow too large, it is probably ok to install praw using sudo.

I was getting the same error as you and I found an answer in the reddit documentation for PRAW. I used HomeBrew to install pip and I'm using Python 3.x instead of the 2.7x that's shipped with OSX, which means I needed to use pip3 instead of pip. It worked right away.
I hope this helps!
