Hello,

New release (0.11.0) is broken for Python 2.x users, below you can find steps to reproduce:

Could you fix this please?

Yes, this is really bad. I spent the last 3 hours trying to get @platformio up and running again. Turns out, it runs against this error. @ivankravets are you already aware of this issue? I am pretty sure you will get tons of false bug reports, as this causes (yet another) Install Endless Loop in Atom....

ivankravets · 2017-11-25T13:02:53Z

@GrimmiMeloni I can't reproduce this issue with my default Python 2.7.10 on macOS. What are your OS and Python version?

Gr1N · 2017-11-25T13:02:56Z

And I found why all builds is green...

To run tests we need to install deps from requirements.txt:

build27:
	virtualenv local --python=python2.7
	local/bin/pip install -r requirements.txt

And as we can see requirements.txt contains backports.functools_lru_cache:

➔ cat requirements.txt
python-dateutil==2.6.0
nose==1.3.0
nose-cov==1.6
chai==1.1.1
sphinx==1.3.5
simplejson==3.6.5
backports.functools_lru_cache==1.2.1

But backports.functools_lru_cache is missing in setup.py...

Gr1N · 2017-11-25T13:05:38Z

I hope this patch should fix issue:

Tested on my local, everything works fine.

Gr1N · 2017-11-25T13:06:51Z

Same issue #491

ivankravets · 2017-11-25T13:07:20Z

@Gr1N You are right, this is a CRITICAL issue. @crsmithdev could you make a new release of "arrow" with adding a dependency to backports.functools_lru_cache?

Thanks!

ivankravets · 2017-11-25T13:08:20Z

'backports.functools_lru_cache;python_version<"3"'

@Gr1N The better is to check Python version and dynamically configure install_requires. Otherwise, we will have an issue with the old version of setuptools.

Gr1N · 2017-11-25T13:11:33Z

Do as you think is right, I just want to get a new package with fix :)

ivankravets · 2017-11-25T13:13:17Z

@GrimmiMeloni temporary fixed as extra deps for @platformio platformio/platformio-core@37a2cce

Please remove %HOME_DIR%/.platformio/penv folder and restart PlatformIO IDE. It should work now.

ramonsaraiva · 2017-11-25T16:17:15Z

Please check the PR i've created to address this issue, we need to push this asap.

ramonsaraiva · 2017-11-25T16:38:45Z

Fixed on https://pypi.python.org/pypi/arrow/0.12.0 - please upgrade arrow if you're using python 2.x and arrow 0.11.0

Gr1N · 2017-11-25T17:46:08Z

Thank you!

GrimmiMeloni · 2017-11-25T21:40:13Z

Nice one, everybody! HotHotfix 😉

arita37 · 2018-01-08T01:40:58Z

still have the issue with 0.12 python 2.7

nebukadhezer · 2018-01-08T15:08:48Z

same here.
Same issue under win7 python 2.7 arrow version 0.12
backports is missing a proper "init.py"

faoiseamh · 2018-02-04T20:22:06Z

For anyone else arriving here, this is resolved in 0.12.1

rmechler · 2018-02-23T21:15:37Z

I'm seeing this with 0.12.1 on Debian 8:

@rmechler This is strange. Can you try a pip install -U arrow and see if the problem persists?

scfl · 2018-03-01T23:21:01Z

I also see this error w/ arrow 0.12.1 (python 2.7.10 on Mac OS 10.11.6):

reynolek · 2018-03-06T21:45:24Z

I am also seeing this issue on 0.12.1

I uninstalled 0.12.1, installed 0.12.0 and it worked fine.

n3storm · 2018-03-12T10:41:36Z

This issue should not be closed?

wilmardo · 2018-03-22T15:29:18Z

I am running into this issue when installing audreyr/cookiecutter (due to cookiecutter > jinja2-time > arrow).

The issue seems to be that pip looks for backports.functools_lru_cache>=1.2.1 and not the pinned backports.functools_lru_cache==1.2.1. If I remove the 1.5 version and install the 1.2.1 it works fine.

What does needs fixing here and where does it needs to be fixed?

This is still an issue on python 2.6 since the current setup.py require only covers 2.7:

ImportError: No module named backports.functools_lru_cache

I guess currently in the setup.py file the require is defined as -
":python_version=='2.7'": ['backports.functools_lru_cache>=1.2.1'],
but should be -
":python_version<='2.7'": ['backports.functools_lru_cache>=1.2.1'],
or using a fixed backports version as suggested above.

As suggested in arrow-py#495 adds support for Python 2.6 and lower

python2.7下
pip install arrow==0.12.0 ,over~~!! 不要最新版本最新版本有问题

bgruber · 2018-12-01T14:26:53Z

FWIW, I just ran into this error when installing aws-sam-cli, which depends on arrow. In my case, the issue was indeed related to installing in the user scheme. This caused pip to install backports.functools_lru_cache in my home directory site-packages, but I also have backports.configparser installed globally. It seems as if the presence of the 'backports' module in global prevents python from seeing the one in my user directory. This problem seems to be specific to 'backports' for some reason.

I was able to temporarily work around the problem by globally installing backports_functools_lru_cache.

systemcatch · 2018-12-14T18:05:33Z

@bgruber that's useful to know, what version of python were you using?

bgruber · 2018-12-15T20:14:31Z

@bgruber that's useful to know, what version of python were you using?

2.7.15 on ubuntu 18.10.

jadchaar · 2019-05-20T00:33:43Z

Is this issue still occurring for people? I am unable to reproduce this on the latest arrow version and python 2.17.16.

Here are the dependencies (and their respective versions) that are installed when I run pip install -U arrow in a fresh virtual environment: arrow-0.13.2 backports.functools-lru-cache-1.5 python-dateutil-2.8.0 six-1.12.0.

jadchaar · 2019-06-23T15:35:30Z

If anyone is still having issues, feel free to report it here. For now, we will close this issue as it seems to be an issue with either backports or pip.

bgruber · 2019-06-24T02:25:58Z

my issue does appear to be resolved on ubuntu 19.04 with python 2.7.16.

jadchaar · 2019-06-24T02:38:05Z

Thanks for letting us know!

I think it is worth compiling a list of solutions to try if this issue occurs again for someone in the future:

Try updating pip: pip install --upgrade pip
Try updating Python 2 to the latest version 2.7.16

Has this been RCA-ed as fixed if I upgrade to 2.7.16? As you can see I'm an LTS kind of person - prefer stuff to just work, not keen to diverge from the standard install if I can avoid it.

@timothycdbarnes thanks for the detailed feedback. Think you can answer a couple of follow up questions for me?

Is arrow installed in a virtual env? Or globally? If it is installed globally, do you have another installation of the backports library (maybe installed by another library or by itself)?
Does this error still occur if you downgrade backports.functools-lru-cache to version 1.2.1?

I am beginning to suspect that this error may be caused by either pip or setuptools version discrepancies. Although we are unable to reproduce this issue, we are attempting a possible fix in this PR: #620.

jadchaar · 2019-07-30T22:52:45Z

We have attempted a fix for this in arrow 0.14.4. Please try this new release and report back if this still occurs. Thanks.

Hi @mkumar118, I recommend removing arrow, backports and backports.functools_lru_cache globally and installing them in a virtual environment. This issue seems to stem from having backports installed globally and this conflicts with the local usage in a venv.

mkumar118 · 2020-07-03T15:54:10Z

Hi @jadchaar
thanks for your input. In my case, setting up a virtual env wouldn't work because these modules are used by a web2py application. If I set up a virtual env, I'll have to modify the entire framework.
For now, my issue is resolved by uninstalling the latest versions of arrow and backports and installing version 0.12.0 of arrow globally.

thank you,
