I noticed that I can’t upgrade from pip because it depends on a new version of nupic.bindings and the pip package looks for the update version on the links page, but can’t find any:

[https://pypi.python.org/simple/nupic-bindings/](https://pypi.python.org/simple/nupic-bindings/)

This also goes for the new version just posted today of nupic.bindings==0.7.0

EDIT: I take that back. Doing a verbose output, I am seeing the following errors from pip

Skipping link [https://pypi.python.org/packages/2c/be/07302a420a9d832c4bcaa0549833c638735734186397dabd47d02331c7ed/nupic.bindings-0.7.0-cp27-cp27m-macosx\_10\_11\_intel.whl#md5=24c3b](https://pypi.python.org/packages/2c/be/07302a420a9d832c4bcaa0549833c638735734186397dabd47d02331c7ed/nupic.bindings-0.7.0-cp27-cp27m-macosx_10_11_intel.whl#md5=24c3b)  
50aae3dea0ec59c9f3e024470a2 (from [https://pypi.python.org/simple/nupic-bindings/](https://pypi.python.org/simple/nupic-bindings/)); it is not compatible with this Python

Apparently, my install python version 2.7.10 is not going to cut it?

EDIT2:

Here is what I have installed now. Not sure why the new versions are unacceptable.

Did you try [uninstalling completely](https://discourse.numenta.org/t/uninstalling-nupic/2175) before reinstalling?

No, but I will do that.

I also updated my python version from 2.7.10 to 2.7.13 just now. I will let you know how it goes.

No luck. Clean distro can’t install with my setup.

Don’t install using `sudo`, that can cause problems.

Try uninstalling `nupic.bindings` again, then run:

`pip install nupic.bindings --user --no-cache`

What happens?

I believe that any 2.7.X version of Python should work. Are you on a 64 bit machine and using 64 bit Python?

Regarding `sudo`, `--user`, etc. You can install packages however you like as long as you are consistent and it works. So if you have been using sudo for everything then I’d stick with that. Although it isn’t the recommended option.

Directly installing nupic.bindings using the above command will install 0.6.1 which the latest working version that I can use. It does not recognize the future versions.

If I try to subsequently install nupic with the same command-line, it fails to find the dependent nupic.bindings which is a future version 0.7.0

Ok, so the question is why not? What error do you get if you run `pip install nupic.bindings==0.7.0`?

I’m also interested in this answer. Also, what OS are you installing on?

Here’s trying to install 0.7.0 directly with verbose output.

[https://pastebin.com/iekWZZYU](https://pastebin.com/iekWZZYU)

I’m running on a Mac. Here is the uname -a output

```auto
Darwin adn448.aero.org 14.5.0 Darwin Kernel Version 14.5.0: Sun Sep 25 22:07:15 PDT 2016; root:xnu-2782.50.9~1/RELEASE_X86_64 x86_64

```

And the Python version

```auto
ADN448:~ jse26711$ python --version
Python 2.7.13
ADN448:~ jse26711$ 

```

[Pypi](https://pypi.python.org/pypi/nupic.bindings/0.7.0) has a wheel for macOS 10.11. What version are you running?

Hmm. My macOS is 10.10.5.

I will work on upgrading it to El Kapitan 10.11 and see if that changes anything.

Or you could try:

```
export MACOSX_DEPLOYMENT_TARGET=10.11
```

Matt,

I upgraded to 10.11 and I am no longer getting the previous error message. It successfully found the package. Now it is having a hard time compiling pycapnp. I’m not sure how to resolve this:

I’ve run into capnp installation problems before. [Installing manually](https://capnproto.org/install.html) fixed my problem.

So what about pycapnp? Do I manually install that as well?

No, it should get installed with nupic.core, and it exists so we can serialize objects in C++ and Python interchangeably. I know there is a way to install without the capnp dependency. You might search the nupic.core github issues for reports on capnp. Or search these forums (if you haven’t already).

So I’ve been plodding along with trying to get pycapnp installed on my MacOSX. I’ve run into one issue after another, but I am steadily making progress. Now I am blocked by a typecasting error in the compilation.

Here is the issue I posted on pycapnp: [https://github.com/capnproto/pycapnp/issues/155](https://github.com/capnproto/pycapnp/issues/155)

You know, I didn’t think this should be this hard. Why all these complications for a simple dependency? Anyway, I’m not getting any help from the pycapnp site, maybe some help here?

Sorry you have having problems with pycapnp. I believe there may be a way to install without this dependency (we do this on our windows builds). I think perhaps @vkruglikov knows something about this?
