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?
