Installing a Python wheel (whl) file using a port

[emcrisostomo (Enrico Maria Crisostomo)]

Hi,

I'm trying to create a port for TensorFlow and since I'm no Python expert I have some doubts about it.

Here is TensorFlow's package on the Python Package Index: ​https://pypi.python.org/pypi/tensorflow/1.4.1. I realised (late) that this package is a wheel package and is meant to be installed with pip or wheel. Even the instruction to install TensorFlow from source (​https://www.tensorflow.org/install/install_sources) describe the process of building a whl package and then install it with pip, so when I realised I thought it wouldn't be a problem.

In the port, I tried to run python -m wheel install archive.whl but I didn't succeed in doing it either in the build or in the destroot phases. Given the kind of error I think I'm forgetting something obvious. This is the port file:

The error I'm getting is

Besides the main error, I certainly have other things where I'd really appreciate some feedback:

• Using that master_site was the only way I got it working. Is there a better way? I tried some acrobatics with the pypi to no avail.
• Downloading a binary package and skip extraction and build is already asked in another issue: ​https://github.com/macports/macports-base/pull/49
• Is using python${python.branch} the correct way to refer to the currently installed python binary? Is there a better idiom to do the same things?

Thanks.

Writing the ticket was like talking to the duck. It's correct that I can't write in that directory because we're still staging the files in ${destroot}. I tried using pip --target ${destroot} but it then complains that:

:info:destroot The directory '/opt/local/var/macports/build/_Users_enricomariacrisostomo_ports_python_py-tensorflow-tensorboard/py27-tensorflow-tensorboard/work/.home/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

and frankly running pip from a port sounds wrong to me.

Trac is not for tech support. Follow-up on the ​Macports Developers mailing list instead.

Thanks Frank.
