pip install

[Anne Schilling]

Hi!

I am having some trouble installing pip packages:

sage -pip install snakeviz
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting snakeviz
  Could not fetch URL https://pypi.python.org/simple/snakeviz/: 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 snakeviz (from versions: )
No matching distribution found for snakeviz

When trying

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

I do have openssl installed:

openssl version -a
OpenSSL 1.1.0e  16 Feb 2017
built on: reproducible build, date unspecified
platform: darwin64-x86_64-cc
compiler: cc -DDSO_DLFCN -DHAVE_DLFCN_H -DNDEBUG -DOPENSSL_THREADS -DOPENSSL_NO_STATIC_ENGINE -DOPENSSL_PIC -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DRC4_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DGHASH_ASM -DECP_NISTZ256_ASM -DPADLOCK_ASM -DPOLY1305_ASM -DOPENSSLDIR="\"/usr/local/mac-dev-env/openssl-1.1.0e/ssl\"" -DENGINESDIR="\"/usr/local/mac-dev-env/openssl-1.1.0e/lib/engines-1.1\"" 
OPENSSLDIR: "/usr/local/mac-dev-env/openssl-1.1.0e/ssl"
ENGINESDIR: "/usr/local/mac-dev-env/openssl-1.1.0e/lib/engines-1.1"

Any ideas?

Just as an additional point of data: as can be seen in the error
message, this is on a Mac. Despite quite some e-mail ping-pong, I have
been unsuccessful trying to help Anne.

Sooo ... What's the recommended way to compile sage on a Mac to have
SSL and thus pip support?

Thanks,
Nicolas

This is not a solution to the pip/ssl problem, but for a single package like snakeviz, you can go to https://pypi.python.org/pypi/snakeviz, download the tar.gz file, and then do

  sage -pip install /path/to/snakeviz-0.4.1.tar.gz

Hi John,

Thank you, that worked!

It would still be interesting to understand whether the pip/ssl problem could be solved.

Best wishes,

Anne

https://trac.sagemath.org/ticket/21944 has some work in this direction.

[Nathan Dunfield]

On a good day, assuming the user has the Xcode command-line tools installed, the following suffices to get pip working with the current binary version of SageMath on macOS 10.12:

sage -i openssl
sage -f python2

It would be great if the next release of SageMath had a working version of pip on macOS as the current situation causes no end of trouble for a lot of people. 

Best, Nathan

Hi Nathan,

Thanks for the suggestion! I had tried this earlier and it had not worked (due to some network issues I had with the computer). But now I tried again and
it actually did work!

Thank you,

Anne
