Re: [IBMiOSS] Error installing pandas

John, both bottle and flipflop have modifications that are not upstream,
thus we ship them as packages. Also, some (many?) customers do not give
their IBM i systems access to the internet, so pip would not work for
them. I would prefer we did not have to ship PTFs for these things as
well, would make my life easier ;)

For ibm_db, that has IBM i changes that has not been merged back in to the
master branch. It will take quite a bit of work to integrate things back
and I've been too busy to do that work right now. Hopefully someday it
happens, but right now you need to install from the PTF packages or grab
the source from github (under the ibmi branch) and build it yourself that
way.

Jim,

What version(s) of Python do you have installed? Is this from the

IBM 5733OPS Option 2 (Python 3.x) or 4 (Python 2.x)? Or is it
another version? Are you doing this installation work into a
chroot’d environment?

Hm. I would have thought, based on another thread ("Re: Resources to
Learn beginner Learning in RPG"), that he's trying this on Litmis,
which has 57733OPS Option 2.

But I have recently opened a Python space on Litmis as well, and I
can't even get as far as he did. For me, any attempt to use pip (to
install any package) results in

[last part of traceback only]
File "/QOpenSys/QIBM/ProdData/OPS/Python3.4/lib/python3.4/site-
packages/pip/_vendor/distlib/compat.py",
line 6
6, in <module>
from urllib.request import (urlopen, urlretrieve, Request,
url2pathname,
ImportError: cannot import name 'HTTPSHandler'

However, I also signed up for pub400.com (currently also only Option
2), and over there, I have successfully installed XlsxWriter, xlrd,
and Bottle (all pure Python, no C compilation involved) using pip
inside a venv.

I tried installing ibm_db (which does have a C component) the same
way, and it failed with

[last part of traceback only]
File "/QOpenSys/QIBM/ProdData/OPS/Python3.4/lib/python3.4/urllib/
request.py",
line 1185, in do_open
raise URLError(err)
urllib.error.URLError: <urlopen error A failure in the SSL library
occurred (_ssl.c:600)>

So, these new offerings are definitely rough around the edges. Both
very cool, but currently not in great shape to leverage both Python
and the i simultaneously. (A huge step would be to install ibm_db and
itoolkit.)

Relevant links, particularly for Holger and Aaron:

https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/
wiki/IBM%20i%20Technology%20Updates/page/Python%20PTFs

Honestly, I don't understand why flipflop and bottle were released as
PTFs for Option 2 (since they are trivially installable with pip), and
perhaps that is why these are not PTFs for Option 4.
