SSL module not available

[Jeroen Sijsling]

Hello,

Recently I got an actual desktop for use in my office. I installed a Linux distribution on it (elementary 0.4, based on Ubuntu). One of the first things I did was to try and install Sage after installing all needed dependencies. To my amazement, that actually worked without any hitch whatsoever. The problems arose when I tried to go further so as to be able to work on the LMFDB.

Developing the LMFDB has a number of prerequisites. Among them is extending Sage by

sage -pip install --upgrade pip

sage -pip install --upgrade pymongo

This fails. I get

jrsijsling@JRS-ThinkCentre-M800z:~/Programs/sage-7.4$ ./sage -pip install --upgrade pip

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping

Requirement already up-to-date: pip in ./local/lib/python2.7/site-packages

jrsijsling@JRS-ThinkCentre-M800z:~/Programs/sage-7.4$ ./sage -pip install --upgrade pymongo

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Collecting pymongo

Could not fetch URL https://pypi.python.org/simple/pymongo/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping

Could not find a version that satisfies the requirement pymongo (from versions: )

No matching distribution found for pymongo

I do have OpenSSL, and the notebook version of Sage works for me. And my version of Python 2.7 did in fact have the ssl module. So I do not know what causes this. The following attempts at a solution have failed:

Fully upgrading Python (pip, pymongo, setuptools) and rebuilding Sage;

Using Sage 7.3 instead;

Running ./sage -i openssl and trying again;

Using the Sage shell.

Running Python (2.7.10, which should have ssl installed internally) inside the Sage shell gives

(sage-sh) jrsijsling@JRS-ThinkCentre-M800z:sage-7.4$ python

Python 2.7.10 (default, Oct 28 2016, 09:09:23) 

[GCC 5.4.0 20160609] on linux2

Type "help", "copyright", "credits" or "license" for more information.

import ssl

Traceback (most recent call last):

File "", line 1, in 

File "/home/jrsijsling/Programs/sage-7.4/local/lib/python/ssl.py", line 97, in 

import _ssl # if we can't import it, let the error propagate

ImportError: No module named _ssl

Any ideas?

Thanks in advance,

Jeroen

[Jeroen Sijsling]

In fact a solution seems to be to use pyopenssl instead:

./sage -i pyopenssl

./sage -f python2

make ssl

Hope this is canonical.

Best,

Jeroen

There is some errors when I install pyopenssl

Could you try first

sage -i openssl

and only then

sage -i pyopenssl

`sage -i openssl` done,

`sage -i pyopenssl` gives the following errors:

Do you need to run "sage -f python2" in between these, to make sure Python builds its ssl module?
 

[Dima Pasechnik]

right, installing openssl still needs python2 rebuild. Sorry, I forgot about this.
thus, the order of packages to be rebuilt:
1) openssl
2) python2
3) pyopenssl

[Eden Harder]

Thank you all! It works!

This helped me after hours and hours of other attempts. Thank you !

[Albert Zeyer]

I get the same error with the latest Sage, downloaded for MacOSX from the website.

Is this still the way to go? I really want to use Python 3 though. How can I enable that?

Best,

Albert

[Jianping Pan]

I just replace the second one with sage -f python3 and it worked for me!
