Good afternoon,
I am trying to find out if there are any end-of-life versions for
Python-Setuptools, and if so, when do these versions typically become
EOL/unsupported? If this information is publicly stored anywhere please let
me know. Thanks.
Hi everyone,
https://setuptools.readthedocs.io/en/latest/deprecated/easy_install.html instructed me that the mailing list would like to know any use cases where Easy_install is felt needed and I believe I have one. and I do not see any posts about this specific use case.
AWS Glue is a serverless runtime environment offered by AWS, usually it runs Spark jobs but Jan 22, 2019 they released Python Shells to run quick snippet codes. they have a fairly comprehensive list of preinstalled libraries and allow you to specify wheels and eggs for anything additional stored on an S3 that you would need, with one limitation - no C-extensions, Cython wheels cannot be installed.
for my use-case I needed to access some SFTPs but Paramiko depends on cryptography for SSH shenanigans and cryptography (along with its dependencies cffi, PyNaCL, and bcrypt) are CPython.
Turns out if you install at runtime there is no issue - it's just with initial setup that has the limitation. of course you then have to install every time that a process runs during paid runtime, rather than startup but better that then not at all.
I tried 2 approaches to install at runtime: subprocess.call(['pip' ...]) and setuptools.command.easy_install.main()
subprocess.call to pip installs pure python very nicely, but every time it hit a CPython wheel/tarball - CFFI, PyNaCl, bcrypt, cryptography, and paramiko - took 6-7 minutes EACH just to install (files were provided locally, downloaded from the S3 from previous attempt seeing what would happen if you just gave it CPython )
In a separate run setuptools...easy_install processed everything in 2 seconds. Somewhere between pkg_resources.getdistribution('paramiko').activate(), importing them, and setting host keys lead to Main process starting a little less than 2 minutes later.
Required use-case? Not technically
Fringe use-case? Fairly
Appreciated that this is still around? Very much, 2-minute startup runtime is appreciated over upwards of half an hour on every single run.
Hello
I have a project with a fairly involved build process where we generate
C++ via a python-clang-based code analyser, generates Python bindings
for the resulting C++ API with SWIG, and finally compile and link to
create various .so's and .py files.
I'd like to package things up with a setup.py script, but from what i
have read, it looks like distutils expects to compile, link and run
swig itself, using distutils.core.setup()'s ext_modules arg?
Is there a way to write setup.py so that it instead runs an external
command (e.g. 'cd foo && make all') when it is asked to build?
Thanks for any help,
- Jules

On behalf of the PyPA and the pip team, I am pleased to announce that we
have just released pip 20.3, a new version of pip. You can install it by
running `python -m pip install --upgrade pip`.
[Cross-posted to
https://discuss.python.org/t/announcement-pip-20-3-release/5948 which
will be easier to read in a web browser and to link to.]
This is an important and disruptive release -- we [explained why in a
blog post last
year](https://pyfound.blogspot.com/2019/12/moss-czi-support-pip.html). We
even made [a video about
it](https://www.youtube.com/watch?v=B4GQCBBsuNU).
## Highlights
* **DISRUPTION**: Switch to the new dependency resolver by
default. (#9019) Watch out for changes in handling editable
installs, constraints files, and more:
https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-res…
* **DEPRECATION**: Deprecate support for Python 3.5 (to be removed in
pip 21.0) (#8181)
* **DEPRECATION**: pip freeze will stop filtering the pip, setuptools,
distribute and wheel packages from pip freeze output in a future
version. To keep the previous behavior, users should use the new
`--exclude` option. (#4256)
* Substantial improvements in new resolver for performance, output and
error messages, avoiding infinite loops, and support for constraints
files.
* Support for PEP 600: Future ‘manylinux’ Platform Tags for Portable
Linux Built Distributions. (#9077)
* Documentation improvements: Resolver migration guide, quickstart
guide, and new documentation theme.
* Add support for MacOS Big Sur compatibility tags. (#9138)
The new resolver is now *on by default*. It is significantly stricter
and more consistent when it receives incompatible instructions, and
reduces support for certain kinds of constraints files, so some
workarounds and workflows may break. Please see [our guide on how to
test and migrate, and how to report
issues](https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-3-2020).
You
can use the deprecated (old) resolver, using the flag
`--use-deprecated=legacy-resolver`, until we remove it in the pip 21.0
release in January 2021.
You can find more details (including deprecations and removals) [in the
changelog](https://pip.pypa.io/en/stable/news/).
## User experience
Command-line output for this version of pip, and documentation to help
with errors, is significantly better, because you worked with our
experts to test and improve it. [Contribute to our user experience work:
sign up to become a member of the UX Studies
group](https://bit.ly/pip-ux-studies) (after you join, we'll notify you
about future UX surveys and interviews).
## What to expect in 20.1
We aim to release pip 20.1 in January 2021, per our [usual release
cadence](https://pip.pypa.io/en/latest/development/release-process/#release-cadence).
You can expect:
* Removal of [Python
2.7](https://pip.pypa.io/en/latest/development/release-process/#python-2-support)
and 3.5 support
* Further improvements in the new resolver
* Removal of legacy resolver support
## Thanks
As with all pip releases, a significant amount of the work was
contributed by pip's user community. Huge thanks to all who have
contributed, whether through code, documentation, issue reports and/or
discussion. Your help keeps pip improving, and is hugely appreciated.
Specific thanks go to Mozilla (through its [Mozilla Open Source
Support](https://www.mozilla.org/en-US/moss/) Awards) and to the [Chan
Zuckerberg Initiative](https://chanzuckerberg.com/eoss/) DAF, an
advised fund of Silicon Valley Community Foundation, for their funding
that enabled substantial work on the new resolver.
That funding went to [Simply Secure](https://simplysecure.org/)
(specifically Georgia Bullen, Bernard Tyers, Nicole Harris, Ngọc
Triệu, and Karissa McKelvey), [Changeset
Consulting](https://changeset.nyc/) (Sumana Harihareswara),
[Atos](https://www.atos.net) (Paul F. Moore), [Tzu-ping
Chung](https://uranusjr.com), [Pradyun Gedam](https://pradyunsg.me/),
and Ilan Schnell. Thanks also to Ernest W. Durbin III at the Python
Software Foundation for liaising with the project.

Hello,
We were trying to create an automated installation process.
As part of this, our software deployment team has requested the installation instructions, which I was unable to locate.
Can you help by pointing me towards them?
Thank you,
Brian

Hi there!
I'm a member of the PyCharm team, and we faced a rather critical issue with the release of pip 2020.3 (https://youtrack.jetbrains.com/issue/PY-45712). It turned out that we actually still used the "--build-dir" option in our internal scripts for installing packages through pip, and we completely missed the fact that it was deprecated. To make the matter worse, a few releases back we implemented automatic upgrading of packaging tools in all virtual environments created in the IDE, so now it's impossible to install anything in a new project unless pip is explicitly downgraded first.
Judging by how pip now operates regarding building of packages, this option can be safely dropped in our wrappers, but we still need some time to prepare and test patches for a few previous releases and upcoming 2020.3. Is it possible to give us some time to soften the blow for the users?
The second question is about the behavior of this option. It appears that we initially started using it because in the past packages were not built in a temporary directory by default. Could you please point me to the exact version of pip where it changed? -- I couldn't find it in a changelog. It would help us decide whether we need to keep some compatibility layer for interpreters with an old version of pip installed.
Thanks a lot!
