Having trouble installing on MacOSX

[Adam Amara]

Hi Everyone,

I'm having trouble installing gc3pie on my mac. I have:

- macOS Sierra

- python 2.7.12

- pip 9.0.0

I followed the instructions on the website and I'm pretty sure my Mac setting are ok (Command Line Tools for XCode, time works etc). After getting a copy of the install script, using curl, I try to run it and I get the message below. I don't know if you have seen this before. I have googled to try to find similar problems but I can't find what I would need to do.

Thanks for help and advice you have

Adam

We have had reports of this sort in the past, which were solved by
this StackOverflow answer:
http://stackoverflow.com/questions/16094187/pip-3-3-ssl-verification-error-mac-osx-10-5-8

Now, that answer is getting old so I wouldn't be sure it helps but maybe try?

If it does not help, can you please post:

- full path of the Python executable
- how you installed it (e.g., came with the OS, Anaconda, homebrew, etc.)
- full path to the `pip` executable
- how you installed it

Thanks!

Hi Riccardo,

Thank you so much for such a quick response.

I tried to follow the advice on the StackOverflow by rolling back to version 1.2.1 of pip (I used pip install pip==1.2.1), but I get the same error message.

My python path is (which python):

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python

this is a soft link that points to:

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

My pip path is (again from which pip):

/opt/local/bin/pip

which again looks like link to 

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pip

I installed pip using macports and I think that also installed my python version. Once I had pip and python, pretty much all my other installations are done with pip.

Thank you again!

Dear Adam,

I do not have a Mac computer to reproduce the error, so what I'm going
to suggest now is a bit of a shot in the dark.

A possible workaround could be:

1. Download file `virtualenv.py
2. Comment out line 339 in `install.py` (the one that reads
`download(VIRTUALENV_...)`
3. Run the installation procedure again.

Dear Adam,

please disregard my previous message! Somehow I hit the wrong key and
an unfinished draft was sent.

I do not have a Mac computer to reproduce the error, so what I'm going
to suggest now is a bit of a shot in the dark.

A possible workaround could be:

1. Download file `virtualenv.py` from
https://raw.github.com/pypa/virtualenv/1.9.1/virtualenv.py and save it
in the same directory where GC3Pie's `install.py` script is.

2. Comment out line 339 in `install.py` (the one that reads
`download(VIRTUALENV_...)`
3. Run the installation procedure again.

Let us know whether this works.

The issue seems to stem from the fact that during the installation
procedure we try to download the `virtualenv.py` directly from its
source repository at GitHub. Your Python installation (via macports)
likely has the SSL certificates for PyPI, python.org and other major
Python sites (so you can successfully install stuff via `pip install`)
but apparently lacks the SSL/TLS root certificate for GitHub.com.
Unfortunately, I have no idea where such root certificates should be
placed on a MacOSX filesystem (in Ubuntu and Debian GNU/Linux, it
would be `/etc/ssl/certs`).

Hope this helps,
Riccardo

Riccardo, Thank you so much!!

That seems to have done the trick. I now get to the magical words:

===============================

Installation of GC3Pie is done!

===============================

Again, thank you.

Adam
