Do you have the right pip version as described [here](https://github.com/numenta/nupic#dependencies)?

Can you try installing pytest alone with sudo?

```
sudo pip install pytest
```

I’m getting this:

I tried “sudo -H pip install pytest”, but I’m still getting the same issue with nupic!!!

Try using **chown** to get ownership of the files  
Or maybe **chmod** if that works on MAC OS

```auto
sudo chown -R $USER /Library/Python/2.7/bin/pytest

```

Try it using different paths, the above is just an example

I have changed all folders and files to which I’m getting access denied to the chown mode. That works a little bit as more progress is achieved during the setup, but unfortunately a new error arise. This is the terminal output:

FYI:  
I tried to use “export MACOSX\_DEPLOYMENT\_TARGET=10.10” but got error related to the configuration. Thus, I re-set the target to 10.13

Thank you…

I would recommend installing(reinstalling) **gcc** or **clang** and trying again. Preference is **gcc**.

Also stackoverflow has much more information about this than this forum could hope to generate.

I tried several suggestions but I’m getting the same error. I reinstalled xcode and clang but nothing changed!!! Also, tried the suggestions in this post but with no luck!!

I have Mac OS Sierra 10.12.6, wondering if anyone can help me out here… This is doing the easy install, however I then tried doing from source and get the same error when running “pip install -r bindings/py/requirements.txt” for nupic.core Any help is appreciated, I am desperate to have a play with the amazing HTM algorithms!

I’d still give **gcc** a try.
